Why shouldn't things be largely absurd, futile, and transitory? They are so, and we are so, and they and we go very well together.

 Apollo 1: The Fire That Shocked NASA
Quote

NASA s Apollo program began with one of the worst disasters the organization has ever faced. A routine prelaunch test turned fatal when a fire ripped through the spacecraft s crew cabin killing all three astronauts. Today marks the 45th anniversary of the Apollo 1 fire, a tragic and preventable accident. There were warning signs, similar accidents that had claimed lives both in the United States and abroad. The Apollo 1 crew could have been saved from a gruesome death.
Plugs Out

The commander for Apollo 1 was Gus Grissom, one of the original Mercury astronauts whose first spaceflight was marred by his capsule s sinking after splashdown. He flew again in Gemini in a spacecraft he named Molly Brown. Senior pilot on the Apollo 1 crew was Ed White, a Gemini veteran who made America s first spacewalk in 1965. Rounding out the crew was pilot Roger Chaffee, a talented rookie more than capable of holding his own with his experienced crew mates. He was a notoriously good guy who took pains to thank everyone for their contributions to Apollo right down to the janitors.
By the end of January 1967, the crew was going through their final prelaunch tests; barring some major setback, they would make the first manned Apollo flight on February 21. One routine test NASA had done since Mercury was the plugs out test, a final check of the spacecraft s systems.

The spacecraft was fully assembled and stacked on top of its unfuelled Saturn IB launch vehicle on pad 34. The umbilical power cords that usually supplied power were removed the plugs were out and the spacecraft switched over to battery power. The cabin was pressurized with 16.7 pounds per square inch (psi) of 100 percent oxygen, a pressure slightly greater than one atmosphere. With everything just as it would be on February 21, the crew went through a full simulation of countdown and launch.
A full launch-day staff of engineers in mission control also went through the simulation. The White Room, the room through which the astronauts entered the spacecraft, remained pressed next to the vehicle. A crew of engineers monitored the spacecraft and were just feet away from the astronauts.

Credit: spacefacts.de Grissom, White, and Chaffee suited up and entered the Apollo 1 command module at 1pm and hooked into the spacecraft s oxygen and communications systems. For the next five and a half hours, the test proceeded with only minor interruptions. Grissom s complaint of a smell like sour buttermilk in the oxygen circulating through his suit was resolved after a short hold, and a high oxygen flow through the astronauts suits tripped an alarm. But these were minor problems and didn t raise any red flags in mission control.
The real problem was communication. Static made it impossible for the crew and mission control to hear one another. An increasingly frustrated Grissom began to question how they were expected to get to the Moon if they couldn t talk between a few buildings.

Engineers in mission control saw an increase in oxygen flow and pressure inside the cabin. The telemetry was accompanied by a garbled transmission that sounded like fire. The official record reflects the communications problem. The transmission was unclear, but the panic was obvious as an astronaut yelled something like they re fighting a bad fire let s get out. Open er up or we ve got a bad fire let s get out. We re burning up. The static made it impossible to hear the exact words or even distinguish who was speaking.
But flames visible through the command module s small porthole window left no doubt about what the crew had said. Engineers in the White Room tried to get the hatch open but couldn t. It was an inward opening design, and neither engineers outside the spacecraft nor the astronauts inside were strong enough to force it open. The men in mission control watched helplessly as the scene played out on the live video feed.

Just three seconds after the crew s garbled report of a fire, the pressure inside the cabin became so great that the hull ruptured. Men wrestling with the hatch were thrown across the room as flames and smoke spilled into the White Room. Many continued to fight their way towards the spacecraft but were forced to retreat as the smoke grew too thick to see through. In mission control, the telemetry and voice communication from Apollo 1 went completely silent.
An hour and a half later, firemen and emergency personnel succeeded in removing the bodies; Ed White was turned around on his couch reaching for the hatch. Over the next two months, the spacecraft was disassembled piece by piece in an attempt to isolate the cause of the fire. The full investigation lasted a year.

The Apollo 1 accident review board determined that a wire over the piping from the urine collection system had arced. The fire started below the crew s feet, so from their supine positions on their couches they wouldn t have seen it in time to react. Everything in the cabin had been soaking in pure oxygen for hours, and flammable material near the wire caught fire immediately. From there, it took ten seconds for spacecraft to fill with flames.
The crew s official cause of death was asphyxiation from smoke inhalation. Once their oxygen hoses were severed they began breathing in toxic gases. All three astronauts died in less than a minute. Many who had tried to save them were treated for smoke inhalation.
The Chamber of Silence

The fire that claimed the lives of Grissom, White, and Chaffee is eerily similar to one that killed cosmonaut Valentin Bondarenko in 1961. Bondarenko was known to his colleagues as a congenial and giving man with great athletic prowess who worked tirelessly to prove he deserved the honour of flying in space.
Part of the cosmonauts training was done in an isolation chamber designed to mimic the mental stresses spaceflight. The room, which the men called the Chamber of Silence, was spartan to say the least. It was furnished with a steel bed, a wooden table, a seat identical to what they would have in the Vostok capsule, minimal toilet facilities, an open-coil hot plate for warming meals, and a limited amount of water for washing and cooking. The chamber was pressurized to mimic the capsule s environment in space. In this case, the oxygen concentration was 68 percent.

During the test, cosmonauts would exercise mental agility with memory games using a wall chart with coloured squares. They would keep busy by reading or colouring subjects were supplied with some leisure material. The silence was frequently interrupted by classical music to see how the subjects reacted to a pleasurable shock. Aside from these distractions, sensory deprivation inside the chamber was absolute. The room was mounted on thick rubber shock absorbers that muffled any vibrations from movement outside, and the 16-inch thick walls absorbed any sound. The cosmonauts communicated with doctors by lights. A light told the subject to apply medical sensors to his body, and a light outside the chamber signaled to doctors that they could begin their tests. A different light would signal the end of the isolation test.
The environment was designed to challenge the cosmonauts mental stability and adaptability. But the hardest part was that no subject knew beforehand how long his test would last. It could run anywhere from a few hours to weeks.

Bondarenko was the 17th cosmonaut to go into the Chamber of Silence and on March 23, his ten day test came to an end. A light signaled that technicians outside had started depressurizing the chamber to match the atmosphere outside. It was a routine part of the test, but this time it was interrupted by a fire alarm.
While he waited to leave the chamber, Bondarenko removed his biomedical sensors and wiped the adhesive off with rubbing alcohol on a cotton pad. In his haste to leave, and exhibiting the lack of concentration expected after ten days of mental testing, he didn t look where he threw the pad. It landed on the hot plate s coil. Cosmonaut Pavel Popovich theorized that he had been standing next to it at the time. Many subjects left the small heater on all the time to warm up the chilly room.

A fire sparked and spread in an instant; everything, including Bondarenko, was saturated with a high concentration of oxygen. Technicians wrenched the door open and exposed the chamber to air, killing the fire instantly, but the damage was done. Doctors pulled a huddled and severely burnt Bondarenko from the room. It s my fault, he whispered when doctors reached him, I m so sorry no one else is to blame. The severity of the fire was immediately obvious. Bondarenko s wool clothes had melted onto his body and the skin underneath had burned away. His hair had caught fire. His eyes were swollen and melted shut.
In Moscow, surgeon and traumatologist Vladimir Julievich Golyakhovsky got a frantic call at his office; the severely burned patient was on his way. Ten minutes later, a team of men in military uniforms arrived carrying the blanket-wrapped cosmonaut. They were accompanied, Golyakhovsky later recalled, by an overwhelming smell of burnt flesh.

Golyakhovsky obliged and gave the patient a shot of morphine in the soles of his feet. It was the one unscathed part of his body thanks to his heavy boots, and the only place the doctor could find a vein. There was nothing he could do to save the man s life. Bondarenko died the next morning. The official cause was shock and severe burns.
Lessons at Home
Parallels between the Apollo 1 crew s and Bondarenko s deaths are obvious, but how each space agency dealt with the deaths was very different. Grissom, White, and Chaffee were each given very public funerals in accordance with their respective military traditions. Bondarenko s death was kept secret, his identity covered by a pseudonym. Not until 1986 did the world hear the true story of his death. This has bred speculation that had the Soviet system been more open, NASA would have know about the dangers of training in a pressurized pure oxygen environment and could have saved the Apollo 1 crew. Former cosmonaut Alexei Leonov even suggested that the CIA knew about Bondarenko since the US had pierced the Iron Curtain before the accident.
But this is unlikely. And besides, NASA wouldn t need to look to the Soviet Union to know the dangers of testing in a pressurized oxygen environment. There were enough incidents in the US to make the danger very clear. Four oxygen fires in the five years before the Apollo 1 accident were proof enough.
 ap1-apollo_1_noID_mc800x666 The Apollo 1 spacecraft nearing the end of the disassembly. Sometime towards the end of March, 1967. Credit: NASA. On September 9, 1962, a fire broke out in a simulated spacecraft cabin at Brooks Air Force Base. The cabin was pressurized to 5psi with pure oxygen. Both subjects were protected by pressure suits. Neither sustained burns, but both were treated for smoke inhalation.
Two months later on November 16, four men had been inside the US Navy s Air Crew Equipment Laboratory for 17 days in an environment pressurized to 5psi of 100 percent oxygen when an exposed wire arced and started a fire. It spread rapidly over the men s clothing and hands for 40 seconds before they were rescued. All were treated for severe burns, and this was the only instance in which the source of the fire was identified.
Two Navy divers were killed on February 16, 1965 in a test of the Navy s Experimental Diving Unit, which was pressurized to 55.6psi to mimic conditions at a depth of 92 feet. It was a multi-gas environment: 28 percent oxygen, 36 percent nitrogen, and 36 percent helium. Somehow, the carbon dioxide scrubbers that were designed to remove the toxic gas from the air caught fire. Pressure inside the chamber rose making it impossible for technicians outside to open the door and remove the men.

A fire broke out during an unmanned qualification test of the Apollo Environmental Control System on April 28. The cabin was pressurized to 5psi of 100 percent oxygen, just like the spacecraft would be in flight. The fire was blamed on a commercial grade strip heater inside the cabin and the incident was consequently dismissed. The commercial material would not be onboard any manned flights. The board that investigated the accident made no mention of the hazardous environment.
A Lack of Imagination
 Apollo_1_patch The Apollo 1 mission patch. Credit: NASA. These accidents weren t secret. NASA knew the dangers of a pressurized oxygen environment, which has prompted conspiracy theorists to suggest that the space agency intentionally put the Apollo 1 crew in danger. But this was hardly the case. In truth, no one at NASA gave much thought to a fire in the spacecraft.
In the early 1960s when Apollo was in its preliminary stages, a dual gas system (likely oxygen and nitrogen) was proposed for the crew cabin. This would have been safer in the event of fire, but more difficult overall. A mixed gas environment requires more piping and wiring, which in turn adds weight. Pure oxygen was simpler, lighter, and was already familiar to NASA. The dual-gas idea was scratched.
NASA did address the possibility of a fire in the spacecraft, but only developed procedures for an event in space when the nearest fire station was 180 miles away. Apollo, like Mercury and Gemini, had no specific fire fighting system on board. The 5psi of oxygen in space was considered too thin to feed a significant fire. Anything that could spark in that environment could be taken care of with a few well aimed blasts from the astronauts water pistol.

With so many engineers on hand for every test, it was assumed that the astronauts would safe so long as fire extinguishers were nearby. But more importantly in the case of Apollo 1 is the plugs out test s status: it wasn t classified as dangerous.
Frank Borman, a Gemini veteran who would go to the Moon on Apollo 8, served as the astronaut s representative to the Apollo 1 accident investigation board. He made this point about the plugs out test s status abundantly clear. I don t believe that any of us recognized that the test conditions for this test were hazardous, he said on record. Without fuel in the launch vehicle and all the pyrotechnic bolts unarmed, no one imagined a fire could start let alone thrive. Borman himself hadn t thought twice when he went through the plugs out test before his Gemini 7 mission. He was confident in NASA and its engineers and stated on record that he would have gone through the Apollo 1 test had he been on the crew.

There had been problems with Apollo w development, and every astronaut had the right to refuse to enter a spacecraft. Although there are sometimes romantic silk-scarf attitudes attributed to this type of business, in the final analysis we are professionals and will accept risk but not undue risks, explained Borman. The Apollo 1 crew felt the dangers were minimal.
With that statement, Borman identified what he considered the crux of the problem and the real reason, however indirect, behind the death of the crew. We did not think, he said, and this is a failing on my part and on everyone associated with us; we did not recognize the fact that we had the three essentials, an ignition source, extensive fuel and, of course, we knew we had oxygen.
 LC34plaque2 A plaque commemorating the Apollo 1 crew on what's left of launch pad 34. Credit: Christopher K. Davis (via Wikipedia). Gus Grissom serendipitously wrote his memoirs during the Gemini program. He addresses the inherent risk of spaceflight in the book s final passage. There will be risks, as there are in any experimental program, and sooner or later, inevitably, we re going to run head-on into the law of averages and lose somebody. I hope this never happens but if it does, I hope the American people won t feel it s too high a price to pay for our space program. None of us was ordered into manned spaceflight. We flew with the knowledge that if something really went wrong up there, there wasn t the slightest hope of rescue. We could do it because we had complete confidence in the scientists and engineers who designed and built our spacecraft and operated our Mission Control Centre… Now for the moon.
Though tragic, their deaths were not in vain. The substantial redesigns made to the Apollo command module after the fire yielded a safer and more capable spacecraft that played no small role in NASA reaching the moon before the end of the decade. It is a fitting tribute to the crew that the plaque on the pad where they perished reads ad astra per aspera a rough road to the stars.

What The Apollo Astronauts Did For Life Insurance
 
Quote

This week, Americans have been remembering Neil Armstrong. But before he walked on the moon, he had to solve a much more prosaic problem.
"You're about to embark on a mission that's more dangerous than anything any human has ever done before," Robert Pearlman, a space historian and collector with collectspace.com, told me. "And you have a family that you're leaving behind on Earth, and there's a real chance you will not be returning."
Exactly the kind of situation a responsible person plans for by taking out a life insurance policy. Not surprisingly, a life insurance policy for somebody about to get on a rocket to the moon cost a fortune.

But Neil Armstrong had something going for him. He was famous, as was the whole Apollo 11 crew. People really wanted their autographs.
"These astronauts had been signing autographs since the day they were announced as astronauts, and they knew even though eBay didn't exist back then, that there was a market for such things," Pearlman said. "There was demand."
Especially for what were called covers -– envelopes signed by astronauts and postmarked on important dates.
About a month before Apollo 11 was set to launch, the three astronauts entered quarantine. And, during free moments in the following weeks, each of the astronauts signed hundreds of covers.
They gave them to a friend. And on important days — the day of the launch, the day the astronauts landed on the moon — their friend got them to the post office and got them postmarked, and then distributed them to the astronauts' families.
It was life insurance in the form of autographs.
"If they did not return from the moon, their families could sell them — to not just fund their day-to-day lives, but also fund their kids' college education and other life needs," Pearlman said.
The life insurance autographs were not needed. Armstrong and Aldrin walked on the moon and came home safely. They signed probably tens of thousands more autographs for free.
But then, in the 1990s, Robert Pearlman says, the insurance autographs started showing up in space memorabilia auctions. An Apollo 11 insurance autograph can cost as much as $30,000.

Moondoggle: The Forgotten Opposition to the Apollo Program 
Quote

For most of our lunar adventure, a majority of Americans did not support going to the moon. On the 50th anniversary of JFK's "We choose to go the moon" speech, we examine why.
 
Today, we recall the speech John F. Kennedy made 50 years ago as the beginning of a glorious and inexorable process in which the nation united behind the goal of a manned lunar landing even as the presidency swapped between parties. Time has tidied things up.
Polls both by USA Today and Gallup have shown support for the moon landing has increased the farther we've gotten away from it. 77 percent of people in 1989 thought the moon landing was worth it; only 47 percent felt that way in 1979.
When Neil Armstrong and Buzz Aldrin landed on the moon, a process began that has all but eradicated any reference to the substantial opposition by scientists, scholars, and regular old people to spending money on sending humans to the moon. Part jobs program, part science cash cow, the American space program in the 1960s placed the funding halo of military action on the heads of civilians. It bent the whole research apparatus of the United States to a symbolic goal in the Cold War.
This chart from the Congressional Research Service shows just how extreme the Space Race's funding levels were, even in comparison to the Manhattan Project or the brief fluorescence of energy R&D after the OPEC oil embargo of 1973.
SpaceRace.jpg
Given this outlay during the 1960s, a time of great social unrest, you can bet people protested spending this much money on a moon landing. Many more quietly opposed the missions. Space historian Roger Launius of the National Air and Space Museum has called attention to public-opinion polls conducted during the Apollo missions. Here is his conclusion:
 
For example, many people believe that Project Apollo was popular, probably because it garnered significant media attention, but the polls do not support a contention that Americans embraced the lunar landing mission. Consistently throughout the 1960s a majority of Americans did not believe Apollo was worth the cost, with the one exception to this a poll taken at the time of the Apollo 11 lunar landing in July 1969. And consistently throughout the decade 45-60 percent of Americans believed that the government was spending too much onspace, indicative of a lack of commitment to the spaceflight agenda. These data do not support a contention that most people approved of Apollo and thought it important to explore space.
moonlanding.jpg
We've told ourselves a convenient story about the moon landing and national unity, but there's almost no evidence that our astronauts united even America, let alone the world. Yes, there was a brief, shining moment right around the moon landing when everyone applauded, but four years later, the Apollo program was cut short and humans have never seriously attempted to get back to the moon ever again.
I can't pretend to trace the exact process by which the powerful images of men on the moon combined with a sense of nostalgia for a bygone era of heroes combined to create the notion that the Apollo missions were overwhelmingly popular. That'd be a book. But what I can do is tell you about two individuals who, in their own ways, opposed the government and tried to direct funds to more earthly pursuits: poet and musician Gil Scott-Heron and the sociologist Amitai Etzioni, then at Columbia University.
Heron performed a song called, "Whitey on the Moon" that mocked "our" achievements in space.

The song had a very powerful effect on my historical imagination and led to me seeking out much of the other evidence in this post. The opening line creates a dyad that's hard to forget: "A rat done bit my sister Nell / With Whitey on the moon." I wrote about this song last year when Scott-Heron died, reflecting on what it meant for "our" achievements in space.
 
Though I still think the hunger for the technological sublime crosses racial boundaries,
[the song] destabilized the ease with which people could use "our" in that kind of sentence. To which America went the glory of the moon landing? And what did it cost our nation to put whitey on the moon?
Many black papers questioned the use of American funds for space research at a time when many African Americans were struggling at the margins of the working class. An editorial in the Los Angeles Sentinel, for example, argued against Apollo in no uncertain terms, saying, "It would appear that the fathers of our nation would allow a few thousand hungry people to die for the lack of a few thousand dollars while they would contaminate the moon and its sterility for the sake of 'progress' and spend billions of dollars in the process, while people are hungry, ill-clothed, poorly educated (if at all)."
This is, of course, a complicated story. When 200 black protesters marched on Cape Canaveral to protest the launch of Apollo 14, one Southern Christian Leadership Conference leader claimed, "America is sending lazy white boys to the moon because all they're doing is looking for moon rocks. If there was work to be done, they'd send a nigger."
But another SCLC leader, Hosea Williams, made a softer claim, saying simply they were "protesting our nation's inability to choose humane priorities." And Williams admitted to the AP reporter, "I thought the launch was beautiful. The most magnificent thing I've seen in my whole life."
Perhaps the most comprehensive attempt to lay out the case against the space program came from the sociologist Etizioni, in his now nearly impossible to find 1964 book, The Moon-doggle: Domestic and International Implications of the Space Race. Luckily for you, I happen to have a copy sitting right here.
moondoggle.jpg
Etzioni attacked the manned space program by pointing out that many scientists opposed both the mission and the "cash-and-crash approach to science" it represented. He cites a 1958 report to the President from his Science Advisory Committee in which "some of the most eminent scientists in this country" bagged on our space ambitions. "Research in outer space affords new opportunities in science but does not diminish the importance of science on earth," he quotes the report. It concludes, "It would not be in the national interest to exploit space science at the cost of weakening our efforts in other scientific endeavors. This need not happen if we plan our national program for space science and technology as part of a balanced effort in all science and technology."
Etzioni goes on to note, and the chart above attests, that this "balanced effort" never materialized.
 
The space budget was increased in the five years that followed by more than tenfold while the total American expenditure on research and development did not eve ndouble. Of every three dollars spent on research and development in the United States in 1963, one went for defense, one for space, and the remaining one for all other research purposes, including private industry and medical research.
He keeps piling up the evidence that scientists opposed or at best, tepidly supported, the space program. A Science poll of 113 scientists not associated with NASA found that all but 3 of them "believed that the present lunar program is rushing the manned stage. Etzioni's final assessment -- "most scientists agree that from the viewpoint of science there is no reason to rush a man to the moon" -- seems accurate.
But that's just the beginning of the book. He has many other arguments against the Apollo program: It sucked up not just available dollars, but our best and brightest. Robots could do our exploration better than humans, anyway. We would fall behind in other sciences because of our dedication to putting men on the moon. There were special problems with fighting the Cold War into space. And even as a status symbol, the moon was pretty lousy.
moonshot2.jpg
But the space program was great in one way: politically. He notes that President Kennedy sought to help the poor and underprivileged but Congress blocked him. So, as Etzioni tells it, you get a massive public works program cleverly disguised as in conservative, flag-waving garb:
 
Put before Congress a mission involving the nation, not the poor; tie to competing with Russia, not slashing unemployment. Economically the important thing was to spend a few billions -- on anything; the effect would be to put the economy into high gear and to provide a higher income for all, including the poor.
But the space program didn't really work out that way. "NASA does make work, but in the wrong sector; it employs highly scarce professional manpower, which will continue to be in high demand and short supply for years to come," he argued.
He laid out an alternative plan with long-term, science-based goals for research funding, a rational peace with the Soviets, and the creation of palatable social programs to develop rural America and help out the poor. But his voice was lost, and in his last few pages, he may have even predicted why.
"In an age that worships technology, when man is lost among the instruments he has created, the space race erects new pyramids of gadgetry; in an age of materialism, it piles on more investments in things when what is needed is investment in people; in an age of extrovert activism, it lends glory to rocket-powered jumps, when critical self-examination and reflection ought to be stressed; in an age of international conflicts, which approach doomsday dimensions, it provides a new focus for emotional divisions among men, when tasks to be shared and to bind them are needed," Etzioni thundered. "Above all, the space race is used as an escape, by focusing on the moon we delay facing ourselves, as Americans and as citizens of the earth."
The race to the moon may not have been wildly popular among scientists, random Americans, or black political activists, but it was hard to deny the power of the imagery returning from space. Our attention kept getting directed to the heavens -- and our technology's ability to propel humans there. It was pure there, and sublime, even if our rational selves could see we might be better off spending the money on urban infrastructure or cancer research or vocational training. Americans might not have supported the space program in real life, but they loved the one they saw on TV.

New Comet Discovered—May Become "One of Brightest in History" 
Quote

 Next year comet 2012 S1 might outshine the moon. 
 
Andrew Fazekas
for National Geographic News
Published September 27, 2012
  If astronomers' early predictions hold true, the holidays next year may hold a glowing gift for stargazersa superbright comet, just discovered streaking near Saturn.
Even with powerful telescopes, comet 2012 S1 (ISON) is now just a faint glow in the constellation Cancer. But the ball of ice and rocks might become visible to the naked eye for a few months in late 2013 and early 2014—perhaps outshining the moon, astronomers say.
The comet is already remarkably bright, given how far it is from the sun, astronomer Raminder Singh Samra said. What's more, 2012 S1 seems to be following the path of the Great Comet of 1680, considered one of the most spectacular ever seen from Earth.
"If it lives up to expectations, this comet may be one of the brightest in history," said Samra, of the H.R. MacMillan Space Centre in Vancouver, Canada.
So what makes a comet a showstopper? A lot depends on how much gas and dust is blasted off the central core of ice and rocks. The bigger the resulting cloud and tail, the more reflective the body may be.

Because 2012 S1 appears to be fairly large—possibly approaching two miles (three kilometers) wide—and will fly very close to the sun, astronomers have calculated that the comet may shine brighter, though not bigger, than the full moon in the evening sky.
(Also see "New Comet Found; May Be Visible From Earth in 2013.")
Refugee From the Edge of the Solar System?
First spotted late last week by Russian astronomers Artyom Novichonok and Vitali Nevski of the International Scientific Optical Network (ISON), comet 2012 S1 was confirmed by the International Astronomical Union on Monday.
But while we know what 2012 S1 is, it's still unclear where it came from. Its orbit suggests the comet may be a runaway from the Oort cloud, where billions of comets orbit about a hundred thousand times farther from the sun than Earth is.
"For astronomers, these distant origins are exciting," Samra said, "because it allows us to study one of the oldest objects in the solar system still in its original, pristine condition."
(Related: "Comet Is Cosmic Snow Globe, NASA Flyby Shows.")
New Comet Bound for Glory?
Right now, 2012 S1 appears to be about 615 million miles (990 million kilometers) from Earth, between the orbits of Saturn and Jupiter, astronomers say.
As the sun's gravity pulls the comet closer, it should pass about 6.2 million miles (10 million kilometers) from Mars—possibly a unique photo opportunity for NASA's new Curiosity rover.
Current orbital predictions indicate the comet will look brightest to us in the weeks just after its closest approach to the sun, on November 28, 2013—if 2012 S1 survives the experience.
As the comet comes within about 1.2 million miles (2 million kilometers) of the sun, the star's intense heat and gravity could cause the ice and rubble to break apart, scotching the sky show. (Related: "Comet Seen Vaporizing in Sun's Atmosphere—A First.")
"While some predictions suggest it may become as bright as the full moon, and even visible during the day, one should be cautious when predicting how exciting a comet may get," Samra said.
"Some comets have been notorious for creating a buzz but failing to put on a dazzling display," he said. "Only time will tell."

I malo o crnoj rupi u središtu galaksije M87, ma koja to bila...
 
 A Spinning Black Hole at a Galaxy's Center 
Quote

  Like all invisible things that are only partly understood, black holes evoke a sense of mystery. Astronomers know that the tremendous gravitational pull of a black hole sucks matter in. They also know that the material falling in causes powerful jets of particles to shoot out of the black hole at nearly the speed of light. But how exactly this phenomenon occurs remains a matter of conjecture, because astronomers have never quite managed to observe the details.
Well, now they have. Sheperd Doeleman, an astrophysicist at the Massachusetts Institute of Technology Haystack Observatory in Westford, and his colleagues have taken the closest look to date at the region where matter swirls around a black hole. By measuring the size of the base of a jet shooting out of the supermassive black hole at the center of the M87 galaxy, the researchers conclude that the black hole must be spinning and that the material orbiting must also be swirling in the same direction. Some of the material from this orbiting "accretion disk" is also falling into the black hole, like water swirling down a drain. The finding appears online today in Science.
For the past few years, Doeleman and his colleagues have been working to link up radio dishes around the world into a virtual telescope with unprecedented magnifying power, which would enable researchers to observe the immediate vicinity of the black hole in the heart of M87—a favorite target for astronomers, as it is one of the brightest objects in the sky. So far, the researchers have linked radio dishes at three sites. That hasn't provided enough resolution to see all the way to the edge of the black hole. But it enabled the researchers to measure the area through which the jet is being emitted.
The size of this emission region fits with only one particular theoretical model of how these jets form. The base of the jet "reduces to the size we measured only when the black hole is spinning and the accretion disk is orbiting in the same direction," Doeleman says. "What we find so exciting is that we are now finally able to measure structures so close to the black hole." He and his colleagues hope to use the Event Horizon Telescope—the instrument being created by linking the radio dishes—to test "whether Einstein's theory of general relativity is valid at the one place in the universe where it might break down: the event horizon of a black hole."
The paper "is very interesting," says Meg Urry, an astrophysicist at Yale University who was not involved in the study. "Measuring the launch point for the jet is absolutely critical for understanding how jets form, and indeed how jet energy is extracted from the black hole-disk system." However, Urry points out, the conclusions rest on a number of assumptions that are "difficult to confirm"—such as whether the measured area does lie directly on top of the black hole rather than off to the side or elsewhere.

This fall, Creative Time will launch The Last Pictures, an archival disc created by artist Trevor Paglen, into outer space, where it will orbit the earth for billions of years affixed to the exterior of the communications satellite EchoStar XVI. To create the artifact, Paglen micro-etched one hundred photographs selected to represent modern human history onto a silicon disc encased in a gold-plated shell, designed at the Massachusetts Institute of Technology (MIT) and Carleton College.

The complete set of one hundred images can be found in The Last Pictures book, co-published by Creative Time Books and University of California Press, available for purchase in bookstores nationwide and online.

Kreće dvogodišnji projekat potrage za Dajsonovim sferama:
 
The Best Way to Find Aliens: Look for Their Solar Power Plants
 
Quote
A team of astronomers is now looking for Dyson Spheres, massive star-scale solar power plants that extraterrestrial hunters hope alien civilizations employ.
 
 
In 1960, mathematician, physicist, and all-around genius Freeman Dyson predicted that every civilization in the Universe eventually runs out of energy on its home planet, provided it survives long enough to do so. Dyson argued that this event constitutes a major hurdle in a civilization's evolution, and that all those who leap over it do so in precisely the same way: they build a massive collector of starlight, a shell of solar panels to surround their home star. Astronomers have taken to calling these theoretical megastructures Dyson Spheres. Dyson's insight may seem like nothing more than a thought experiment, but if his hypothesis is sound, it has a striking implication: if you want to find advanced alien civilizations, you should look for signs of Dyson Spheres.
Last month a trio of astronomers led by Penn State's Jason Wright began a two-year search for Dyson Spheres, a search that will span the Milky Way, along with millions of other galaxies. Their project was just awarded a sizable grant from the Templeton Foundation, a philanthropic organization that funds research on the "big questions" that face humanity, questions relating to "human purpose and ultimate reality."
So how do Wright and his team aim to find a Dyson Sphere? Though the word "sphere" summons to mind a solid structure, Wright says his team won't be looking for solid shells. "Even though there is enough mass in our solar system to construct a solid sphere, such a structure would not be mechanically feasible," Wright told me. "It would probably have to be more like a swarm of collectors."
This wild speculation about futuristic alien tech probably seems unscientific, but the search for extraterrestrial civilizations has always depended upon such speculation. Think of all the predictions that are baked into SETI, the Search for Extraterrestrial Intelligence, which uses telescope arrays to scan the heavens for alien radio communications. At present, humans have nowhere near the excess energy you'd need to send the kind of radio signal that SETI is looking for. Earlier this year, astronomer Robert Gray told me that "to operate a radio beacon that is on all the time, broadcasting in all directions, strong enough to be picked up from many light years away, you need an enormous amount of energy -- something in the range of thousands and thousands of big power plants." SETI is betting that advanced civilizations will value communicating with other civilizations a lot, or at least enough to justify huge energy expenditures. It's also betting that such civilizations will communicate via radio waves, and that they will transmit their signals on one of the frequencies that we monitor. For us to find intelligent extraterrestrials, it's not enough that they exist; they have to develop and use technology in predictable ways.
 
Compared with SETI, a search for Dyson Spheres assumes a lot less about the goals of futuristic alien civilizations. In fact, most of its assumptions proceed directly from simple biology. As Wright, the project leader, explained to me, "life, by definition, uses energy, which it must reradiate as waste heat." The larger the civilization, the more energy it uses and the more heat it reradiates. Life also (by definition) reproduces, which introduces the possibility of exponentially increasing energy demands. If left unchecked, those increases will eventually outstrip the available energy on a planet. That would leave a growing civilization no choice but to mine energy from other planets and, eventually, their stars.
Let's use the Earth as a test case. As Oliver Morton has pointed out with a lovely metaphor, the sun beams a total of 120,000 terawatts per day onto our planet. That's 10,000 times the amount that flows through our industrial civilization. That's a lot of energy, but remember that our industrial civilization is young, and growing fast. In just the past 30 years, we've doubled our global energy supply. At that doubling rate, in 400 years we will be collecting or generating enough energy to match the total sunlight that comes to our planet. At that point, it may be time to draw up plans for a Dyson Sphere.
It's conceivable that an advanced alien civilization could be exponentially more energy-intensive than ours, especially when you consider that its industrial revolutions and energy doublings may have begun billions of years ago. Dyson Spheres could be an ancient and prolific phenomenon in our universe.

Dyson Spheres also fit squarely within with another theoretical model of civilizational advancement: the Kardashev Scale. In 1964, Soviet astronomer Nikolai Kardashev tried to plot out a theory of technological advancement based on a civilization's mastery of larger and larger energy sources over time. Under the Kardashev Scale, a Type I civilization uses all of the energy available on its home planet, a Type II civilization uses all of the energy from its local star, and a Type III civilization makes use of all the energy in its galaxy. The search for Dyson Spheres is, in essence, a search for Type II civilizations. And because it is premised on a civilization's energy usage, it has another advantage over efforts like SETI's: It allows us to find aliens that aren't necessarily interested in talking to us.
That's because if Dyson Spheres exist, they promise to give off a very particular kind of heat signature, a signature that we should be able to see through our infrared telescopes. The solar energy collected by a Dyson Sphere would heat it, the same way that your computer heats up when it uses electricity. That heat would radiate off the sphere as infrared light rather than visible light. "A Dyson Sphere would appear very bright in the mid-infrared," Wright explained to me. "Just like your body, which is invisible in the dark, but shines brightly in mid-infrared goggles."
A civilization that built a Dyson Sphere would have to go to great lengths to avoid detection, either by getting rid of its waste heat in some novel way, or by building massive radiators that give off heat so cool that it would be undetectable against the cosmic microwave background, the faint afterglow of the Big Bang. Wright told me that the latter solution would involve building a sphere that was a hundred times larger than necessary. "If a civilization wants to hide, it's certainly possible to hide," he said, "but it requires massive amounts of deliberate engineering across an entire civilization."
Wright's project won't be the first search for Dyson Spheres. In the 1980's, researchers at Fermilab looked for Dyson Sphere signatures in the data generated by IRAS, the first ever space-based infrared survey of the sky. They found several candidate sources, but on closer inspection they turned out to be giant stars, or else dusty objects that absorb starlight and then reradiate it.
 
Wright's group will have access to data that Fermilab's researchers could only dream of. They'll be scanning three different infrared sky surveys, including NASA's Wide-field Infrared Survey Explorer (WISE) (pictured up top) which is hundreds of times more sensitive than IRAS. They'll be looking for Dyson Spheres in our galaxy, but also for whole galaxies with excess waste heat -- galaxies that may contain a large number of stars enshrouded in technological megastructures.
If Wright and his team find something outside the range of expected astronomical phenomena, a lengthy confirmation process will begin, a process that will likely involve astronomers and telescopes across the world. Wright was careful to note that no matter what the initial data indicates, he won't be jumping to any conclusions. "More than once some inexplicable object has been discovered that looked like aliens, and then slowly it became clear that it was a very interesting, but totally natural, phenomenon," he said. Indeed, Nikolai Kardashev once thought he'd identified several good candidates for Type III civilizations, which operate on a galactic scale. But in the end, they turned out to be quasars.
Near the end of our conversation, I asked Wright if Dyson Spheres and the Kardashev scale had any competitors, if there were other theoretical models that described what extraterrestrial civilizations might look like. "I'm not aware of any other scales in the refereed scientific literature," he said, "but there probably are some." In astrobiology, the line between science and science fiction is blurry. "Often the best discussions of these issues are in paperback novels," Wright noted. "I can tell you, it's strange to write a serious research proposal and have half of your bibliography be science fiction."

Сјајан скок, скоро савршен. Гледао сам пре извесног времена документарац о оваквим скоковима, где је овај и најављен. Било је снимака упадања у ковит и они се увек догађају на почетку скока. Потом падобранац успе да исконтролише лет. Зашто се то догађа углавном на почетку, то мора да одговори неко стручнији. Мени се лаички чини да људско тело мора да се прилагоди тим екстремним условима кретања и да истренирани падобранац углавном успе да превазиђе кризу. Иначе, веома је брзо пада у несвест у таквим ситуацијама, петнаестак секунди је ваљда критична граница при бржем окретању. Мозак се пребрзо мућка.  :)

Takođe sam laik, ali načuh da profesionalci pričaju kako na se na velikim visinama (1km<), potpuno gubi osećaj straha od visine. Da se vidi samo slika i da ne postoji osećaj blizine prostora koji bi trebao biti koban.

A doskok, šta reći a ne zaplakati. Svaka čast. Kako bih voleo da sam imao te skilove kada sam u osnovnoj išao svaki dan u školu 50-icom (ko zna šta je autobus 50, pripremljen je za pakao), pa si ako imaš sreće da se uguraš izlazio često i na dupe. Ali zato je zimi bilo gotivno.

Lilit kaže neće biti skorijeg spuštanja na mesec i to je verovatno tačno. Zato nam i uvaljuju ovaj surogat. Mislim, sve je to lepo kad se ima para, ali ovaj Šmajserberg ili kako već je heroj onoliko koliko i Novak Đoković. A doktor Šaran na B92, na kraju prenosa reče, prisustvovali smo stvaranju mita, rođenju heroja... E pa ne znam bi li se Elijade, Frejzer, Kembel, Grevs i ostali složili sa time, ali jeste istina da se u XX-XXI veku mitovi malo brže fabrikuju.

Nisam neki zagriženi konspirolog, nisam se posebno udubljivao u promišljanja o značaju ovog događaja za civilizaciju, ali eto, samo da napomenem da može ovaj događaj na puno načina da se čita. Jedan od njih je bez usplahirenih voditelja.

Felix Baumgartner stepped out of the space capsule an astonishing 128,100 feet, or 24.26 miles above earth, about three times the cruising altitude of jetliners. The skydiver plummeted for 4:20 seconds, but it seemed an eternity, because his faceplate was fogging up on the way down as he fell through harsh atmospheric conditions at a dizzying speed.

Baumgartner was also thrown into a dangerous tumble shortly after exiting. "It felt like a flat spin," said Baumgartner. "I had a lot of pressure in my head, but I felt I could regain control so we could go after the sound barrier."

According to Brian Utley, who's responsible for FIA certification, roughly one minute into his jump Baumgartner reached a top speed of 833.9 mph, a new record for a skydiver. That also means he successfully broke the sound barrier, reaching Mach 1.24.

He also broke the record for the highest manned balloon flight, unofficially reaching a height just shy of 25 miles. He did so in a balloon that's also the largest ever manned.

Baumgartner's long-anticipated leap from the edge of space was the Austrian daredevil's attempt at breaking all those records, most notably the highest successful jump and becoming the only skydiver to break the sound barrier.

Baumgartner is the first skydiver to ever break through the sound barrier, and remarkably, it comes 65 years to the day after Chuck Yeager, flying in his X-1A, first broke through the harrowing milestone.

As Baumgartner opened the hatch of his capsule and stepped out onto the platform, he said before jumping, "I wish the whole world could see what I see."

After landing, he said the only thing he was thinking about once on the platform was getting back to earth alive. "At that height you become so humble, you don't think about breaking records anymore. You just want to come back."

STORY: Behind the massive Red Bull Stratos balloon, and its climb to the edge of space

The Red Bull Stratos project had been seven years in the making. Baumgartner, 43, made the leap while wearing a pressurized space suit. He jumped from a pressurized capsule that was hoisted toward the heavens above Roswell, New Mexico, by a towering white stratospheric balloon.

During the marathon free-fall, Baumgartner's unofficial speed of 706 mph came while passing through sub-freezing air zones. While falling, he was communicating with mission control that his visor was fogging up, which is the likely reason behind his early parachute deployment, at 4:20.

The epic jump, the team has maintained, represents more than a mere stunt. Extensive research that went into this mission is expected to help scientists design safer and more effective space suits for future astronauts.

Family and friends were on hand, with his mother, Eva, describing the feat as Baumgartner's "biggest dream coming true."

Baumgartner, whose mission was planned cautiously and meticulously by a team of scientists, shattered a 52-year-old skydiving altitude record of 102,800 feet. That belonged to Joseph Kittinger, a former U.S. Air Force colonel, who joined the Red Bull Stratos project as chief of flight operations and safety.

Last March the skydiver and famous BASE jumper made a preparation jump from 71,580 feet (more than 13 miles) above Roswell. During that leap he set a world free-fall speed record of 364.4 mph. The free-fall spanned 3 minutes, 43 seconds, and included a plunge through temperatures as cold as minus-75 degrees.

Baumgartner became so cold that he could hardly move his hands, and the free-fall was so long that he had to fight the urge to deploy the parachute too early.

Remarkably, two others had survived jumps from similar altitudes--both in the 1960s. They were Russia's Eugene Andreev and American Joseph Kittinger.

In July Baumgartner made his final test jump, from 97,146 feet, also in Roswell.

The balloon was launched from the back of a pickup truck. For 52 years Kittinger, who also wore a pressurized suit, held the distinction of taking what had been described as "the highest step in the world."

It was during an era in which nobody knew whether a human could survive a jump from the edge of space. A handful of people died while trying to beat Kittinger's record.

Before Sunday's jump, Baumgartner said of the mental struggles: "You get claustrophobic fast in the pressurized suit. You start to let your mind go, and you think of people who lost their lives trying to do what Joe Kittinger did. You have to get your mind in a different place. Count backwards ... whatever you have to do."

Kittinger added: "Of course it's not easy. It takes a special combination [of talent]. The best partner you can have is Felix Baumgartner."

On Sunday, Kittinger had a special message for all the doubters at the post-jump press conference. "I'd like to give a special one finger salute to all those who said he'd come apart going supersonic."

When Felix Baumgartner was asked what's next now that he's achieved this long awaited dream, he replied, "Well, in forty years I'd like to be in the seat Joe Kittinger is in today, helping somebody try to break my record."

Joj, pa naravno da ga je povukla, znači izračunali su sa sigurnošću na koju visinu može da otpluta i da se baci na Zemlju, iako je otišao 3 km više od predviđene. Bilo je nekih priča ako se pravilno ne odrazi da će ostati da pluta, zar ne.

30 kilometara iznad površine Zemlje je još uvek malo u poređenju sa prečnikom Zemlje od [malo guglovanja] 6371 km. Sila gravitacije opada sa kvadratom udaljenosti od centra planete, i nema neke preterane razlike u gravitaciji između 6371 i 6401 kilometara udaljenosti od centra.

Mikrogravitacija (bestežinsko stanje -pogrešan termin) se ne postiže visinom, nego brzinom. No, pošto se Feliks penjao izuzetno malom brzinom, ne bi osetio mikrogravitaciju (orbitu bez intervencija u korekciji iste) ispod 1000 km a da ne piči prvom orbitalnom.

Mikrogravitaciju bi dosegao i na visini od oko 150 km, ali ne zadugo. Gravitacija bi ga vrlo brzo uzela pod svoje.
Već na 250 km bi mogao da "pluta" maksimalno sedam dana, onda bi se sljuštrio nazad, ka zemlji.

ISS svakih mesec dana pali motore i vrši korekciju putanje, iako se nalazi na "samo" 350 km, da bi se otela od ono malo otpora atmosfere što je ostalo na toj visini.

The tech behind Felix Baumgartner’s stratospheric skydive 
Quote

Sixty five years ago today, Captain Charles Yeager became the first man to travel faster than the speed of sound in his X-1 aircraft. Daredevil Felix Baumgartner just became the first man to accomplish the same feat without a plane — or indeed any assistance at all. In an almost unimaginable stunt, the 43-year old Austrian has jumped from a specially constructed balloon at over 128,000 feet (39km) above the earth, breaking the world record for high-altitude skydives and speeds in free fall. As you would expect, Baumgartner is no stranger to extreme sports. He is an accomplished BASE jumper and, using a carbon wing, was the first to free fall across the English Channel. On this dive he broke not only the previous altitude record of 102,000 feet for a skydive, but likely the speed of sound and the record for fastest free fall during his descent.
The Red Bull Stratos team backing Baumgartner describes their feat as a “mission to the edge of space.” Years in the planning, the team has gone through many iterations of equipment and practice jumps before finally being ready to make the record-setting attempt from Roswell, New Mexico. Capsule damage during a training jump and poor wind conditions took turns delaying the effort, but today, Sunday, October 14th, 2012, Baumgartner was finally able to launch.
Read: The best photos and videos from Felix Baumgartner’s Red Bull Stratos sky dive
 Getting up there Stratos balloon being filled with Helium -- It is 55 stories high when fully inflated, and a 400+ foot sphere at altitudeEven getting high enough to make the record jump is a technical challenge. 128,000 feet (over 39,000 meters) is several times higher than the altitudes frequented by commercial jets. It even surpasses world altitude record of 123,520 feet for jet aircraft. So getting there isn’t simply a matter of hitching a ride on a plane. Baumgartner used a specially-designed balloon with a spaceship-sized capsule suspended underneath to make his ascent.
To put this altitude in perspective it is more than three times further than the seven miles James Cameron went below the surface of the ocean to reach the depths of the Mariana trench. Like Cameron’s journey, Baumgartner’s was a solitary one, packed into his one-man capsule suspended under the helium-filled Stratos balloon for his three-hour ride up.
 Surviving in space The journey up was the cushy part of the flight for Baumgartner. His 2,900-pound (1315kg) capsule is fully climate controlled. It was damaged in a hard landing during a test jump in July, which pushed the team’s schedule back to allow for repairs. Similar to Cameron’s sub, the capsule features a pressure sphere, although a six foot one made out of fiberglass and epoxy instead of the four foot version made from metal that Cameron needed. During the ascent, the sphere is pressurized to 8 psi, about the same pressure as the atmosphere at 16,000 feet above sea level.
Much like a race car cockpit, the sphere is surrounded by a cage of chromium-molybdenum (chromoly steel) tubing. An outer insulated shell of fiberglass helps protect the capsule from the -70 degree Fahrenheit (-56.7C) temperatures. An aluminum honeycomb at the bottom of the capsule protects the sphere during landing. Additional, one-time-use crush pads of cell-paper honeycomb can withstand up to 8Gs on impact.
Diagram of Stratos high-altitude record-setting mission flight plan
 A lifetime of dry cleaning, all in one bag Red Bull describes its Stratos balloon as a forty-acre dry cleaning bag. Made out of strips of plastic film which are only .0008-inches (0.02mm, 20 micron) thick, the balloon material would cover nearly 2,000,000 square feet (162,000 square meters). Polyester-fiber tape is used to reinforce the material. At launch the helium-filled balloon is 55 stories high, and very thin. As it ascends, the balloon expands, eventually holding a staggering 30,000,000 cubic feet of helium as it becomes nearly round — 334 feet high and 424 feet wide. Two trucks of helium are needed to inflate the balloon, a process taking nearly an hour. The balloon is remotely emptied, returned to earth, and hopefully recovered after a jump. I’m thinking that I wouldn’t want to be standing underneath it when it drifts down.
 Space walking at the speed of sound Baumgartner’s suit is essentially a highly-ruggedized spacesuit. Eight pounds of composite materials provide him with a 3 psi environment for his entire trip down, and protects him from the extreme temperatures he’ll experience. He doesn’t need to try to breathe 3 psi air, as the suit provides him with pure oxygen.
Baumgartner space suit diagramA main and reserve chute are of course essential equipment for Baumgartner. They are only designed to be deployed up to about 172 mph (277 kph), so Baumgartner needs to slow down, by entering the thicker atmosphere closer to earth after about five minutes of free fall, before safely pulling his rip cord. There is a fail-safe which could have deployed the main chute if he had been moving at more than 115 feet (35 meters) per second at 2,000 feet (610 meters) or less altitude. Fifteen more minutes of floating down on his parachute got Baumgartner safely on the ground.
Baumgartner has almost certainly also set a world record for speed, as well as height. During the jump his team measured his top speed at nearly 730 mph, well above the speed of sound and the previous record. His chest pack includes an instrument package that will be used by officials to verify whether he did indeed break the sound barrier during his free fall. If the team’s calculations are correct Baumgartner broke through the speed of sound — approximately 690 miles per hour — within a minute after jumping. Lower-altitude jumps are limited in speed by the drag of the atmosphere, but at over 100,000 feet the air is thin enough to allow much greater speeds.
Amazingly the team kept visual contact with Baumgartner during the jump and was able to transmit live video of the event. For most of the jump, except for a period when he was tumbling, Baumgartner could also be heard speaking with the team, including relaying that his leg was swelling up during the free fall. The only one of the records Baumgartner set out to shatter that didn’t fall was time in free fall. He pulled his rip cord and successfully deployed his main chute about four minutes and 22 seconds after jumping, instead of the over six minutes he had hoped for — probably because his free fall speeds were higher than expected.
Felix Baumgartner, seen from Red Bull Stratos mission control
 Spinning, and not in a good way We’ve all seen video of airplanes going into a tailspin. Diving from altitude carries the same risk, except magnified because a human body can spin much faster than a plane. The resulting force is enough to cause unconsciousness and potentially a “redout” leading to brain injury. The Red Bull team equipped Baumgartner’s rig with a special drogue chute that could have deployed to stabilize him if a suit-mounted G meter registered over 3.5 Gs for more than six seconds. The closest Baumgartner got to this type of problem was tumbling mid-way through his free fall, which he quickly corrected.
 Covering the jump: Beyond Google Glass Baumgartner's chest pack with electronics and cameraGoogle might have made waves broadcasting a low-altitude jump with Google Glass cameras and special antennas, but this jump required a much more extreme set of cameras and communication technology. The capsule itself featured nine HD cameras and three 4K cameras, along with three more high-resolution digital still cameras. Because of the altitude, critical electronics components are housed in a pressurized “keg” that contains two miles of wires.
Four of the twelve capsule cameras are rated for space and life outside the capsule, while eight of them live in nitrogen-filled housings on the exterior, and three are in the interior. All the cameras are remotely controlled from the ground, and filled three microwave channels with video during the flight. Baumgartner’s suit also had three HD video cameras, one on each thigh and one on his chest.
None of this was enough to get the jump broadcast live. A unique ground system, nicknamed JLAIR for Joint Long-range Aerospace Imaging and Relay, had to be developed to track the capsule and Baumgartner during the flight and dive. Using several massive telescopes and high-powered zoom lenses mounted on a four-ton motorized pedestal the JLAIR kept the broadcast antennas focused on target.
 A link to the past In an unlikely parallel to Cameron’s deep-sea dive, Baumgartner also broke a record that is over fifty years old. In 1960, then Air Force Captain Joe Kittinger sky dived from 102,800 feet, also over New Mexico. Like Don Walsh’s dive to the Challenger Deep of the Mariana trench in the Trieste in 1960, it was done at a time before much of the technology in use today was invented. Kittinger is a consultant to the Red Bull Stratos project, just as Walsh was to Cameron’s effort. Kittinger’s jump was chronicled on film, and has been turned into a YouTube video with a rock sound track. Look for the guy checking the free fall time with a stopwatch:

It’s hard to imagine the feeling of jumping out of a space capsule 22 miles above the earth and simply falling for over four minutes as space turns into sky. Fortunately for Baumgartner he was able to keep his wits together, control his body position, and successfully pull his rip cord to make a great landing — steering his parachute to an open area and walking as he landed. After this, the most awesome of his many feats, he plans to settle down with his family and merely fly helicopter rescue flights for adventure.

Gaddemit, a mi mislili Feliks neka šmekerčina:
 
 Direktor "Gugla" skočio sa ivice svemira, novi rekord
 
Quote
Direktor Gugla Alen Justas skočio je sa ivice svemira i probio zvučni zid i time oborio rekord koji je pre dve godine postavio Feliks Baumgartner.
 
On je juče u apsolutnoj tajnosti skočio sa visine od skoro 42 kilometra i postavio novi rekord, samo dve godine nakon rekorda Feliksa Baumgartnera, koji je skočio sa visine od 39.044 metra.
 
Justas (57), koji je sam finansirao ovaj poduhvat, skočio je sa neverovatnih 41.842 metara, a skok sa ivice svemira do tla trajao je 15 minuta, javljaju agencije.
 
On je juče ujutro po lokalnom vremenu se balonom napunjenim helijumom iz Novog Meksika popeo do stratosfere, odakle je skočio, a dok je padao kretao se brzinom većom od 1.300 kilometara u sekundi.
 
On je nosio specijalno dizajnirani skafander, dok se Baumgartner peo u kapsuli. Pripreme za ovaj poduhvat trajale su 34 meseca.

China completes first mission to moon and back




Quote
BEIJING: China completed its first return mission to the moon early Saturday with the successful re-entry and landing of an unmanned probe, state media reported, in the latest step forward for Beijing´s ambitious space programme.

 

The probe landed safely in northern China´s Inner Mongolia region, state news agency Xinhua said, citing the Beijing Aerospace Control Center.

 

Xinhua said the probe took "some incredible pictures" of the Earth and the moon.

 

Prior to re-entering the Earth´s atmosphere, the unnamed probe was travelling at 11.2 kilometres per second (25,000 miles per hour), a speed that can generate temperatures of more than 1,500 degrees Celsius (2,700 degrees Fahrenheit), the news agency reported.

 

To slow it down, scientists let the craft "bounce" off Earth´s atmosphere before re-entering again and landing.

 

The probe´s mission was to travel to the moon, fly around it and head back to Earth, the State Administration of Science, Technology and Industry for National Defence (SASTIND) said in a statement at its launch eight days ago.

 

The module would have been 413,000 kilometres from Earth at its furthest point on the mission, SASTIND said at the time.

 

The mission was launched to test technology to be used in the Chang´e-5, China´s fourth lunar probe, which aims to gather samples from the moon´s surface and will be launched around 2017, SASTIND previously said.

 

Beijing sees its multi-billion-dollar space programme as a marker of its rising global stature and mounting technical expertise.

 

The military-run space project, which has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon, is also seen as evidence of the ruling Communist Party´s success in turning around the fortunes of the once poverty-stricken nation.

 

China currently has a rover on the surface of the moon.

 

The craft, called the Jade Rabbit and launched as part of the Chang´e-3 lunar mission late last year, has been declared a success by Chinese authorities, although it has been beset by mechanical troubles. (AFP)

Najveći problem na dugačkim kosmičkim putovanjima je, kako nas je i dosta nauične fantastike podučilo - dugotrajna izolacija. Kako se protiv toga boriti?


Moving to Mars





Quote
On a clear, cold day in March, 1898, a converted seal-hunting ship named the Belgica gave up struggling against the pack ice of the Bellingshausen Sea and resigned itself to the impending Antarctic winter. The ship was carrying a scientific expedition with an international crew, rare in that phase of polar exploration: nine Belgians, six Norwegians, two Poles, a Romanian, and an American, the ship’s doctor. The expedition’s organizer, a Belgian naval lieutenant named Adrien de Gerlache, had handpicked officers and scientists for their expertise; the mariners who slept in the forecastle had been signed up more casually. None had been selected for character, resilience, or survival instinct. The crew had expected the Belgica to winter over in warmer latitudes. No ship had ever spent a winter locked in the Antarctic ice.
An eerie despondency settled over officers and crew as the days grew short and ice groaned against the hull. Low on coal and lacking proper gear, they sewed winter coats out of blankets. Conversation trailed away, and dinners of tinned meat were greeted with derision. Starting in May, the sun disappeared for two months, and the crew gradually fell apart. A young Belgian geophysicist succumbed to a weak heart, and was buried through a hole in the ice. De Gerlache and the ship’s captain, Georges LeCointe, wrote out their wills and retired to their rooms. One crewman, convinced that the others wanted to kill him, hid away at night, while another tried to leave the ship, announcing plans to walk home to Belgium. Even the ship’s cat withdrew and died. The American doctor, Frederick A. Cook, wrote in his journal that a “spell of indifference” had afflicted him and his shipmates. “Around the tables, in the laboratory, and in the forecastle, men are sitting about sad and dejected, lost in dreams of melancholy,” he noted. “We are at this moment as tired of each other’s company as we are of the cold monotony of the black night and of the unpalatable sameness of our food.”
Cook later became infamous for faking two heroic firsts, the conquest of the North Pole and the ascent of Mt. McKinley. But that winter on the Belgica was an occasion of genuine heroism. Assisted by the ship’s Norwegian first mate, Roald Amundsen, Cook instituted an exercise routine on the ice, walks around the ship known as the “madhouse promenade.” He introduced a “baking treatment” for the men with the lowest morale and the weakest heartbeats, which entailed seating them before the warm glow of the ship’s coal stove. He insisted that the crew start eating the vitamin-rich meat of penguins, which even he described as tasting like a mixture of mammal, fish, and fowl parts, roasted in blood and cod-liver oil. He helped organize entertainments, including a beauty contest among illustrations torn from magazines, with voting categories such as “Alabaster shoulders,” “Supple waist,” and “Irreproachable character.”
With the return of summer, Cook and Amundsen rallied the crew for a monthlong effort to saw a channel to open water. De Gerlache and his men returned to Europe as heroes, and Amundsen—who later achieved renown as a polar explorer—credited the doctor with saving their lives. But the Belgica’s experience became a cautionary tale for the planners of future expeditions to the poles. When Richard Byrd set out, in 1928, to establish a camp in Antarctica, his supplies included two coffins and twelve straitjackets.
A century after the Belgica’s return, a NASA research consultant named Jack Stuster began examining the records of the trip to glean lessons for another kind of expedition: a three-year journey to Mars and back. “Future space expeditions will resemble sea voyages much more than test flights, which have served as the models for all previous space missions,” Stuster wrote in a book, “Bold Endeavors,” which was published in 1996 and quickly became a classic in the space program. A California anthropologist, Stuster had helped design U.S. space stations by studying crew productivity in cases of prolonged isolation and confinement: Antarctic research stations, submarines, the Skylab station. The study of stress in space had never been a big priority at NASA—or of much interest to the stoic astronauts, who worried that psychologists would uncover some hairline crack that might exclude them from future missions. (Russia, by contrast, became the early leader in the field, after being forced to abort several missions because of crew problems.) But in the nineteen-nineties, with planning for the International Space Station nearly complete, NASA scientists turned their attention to journeys deeper into space, and they found questions that had no answers. “That kind of challenging mission was way out of our comfortable low-earth-orbit neighborhood,” Lauren Leveton, the lead scientist of NASA’s Behavioral Health and Performance program, said. Astronauts would be a hundred million miles from home, no longer in close contact with mission control. Staring into the night for eight monotonous months, how would they keep their focus? How would they avoid rancor or debilitating melancholy?
 Stuster began studying voyages of discovery—starting with the Niña, the Pinta, and the Santa Maria, whose deployment, he observed, anticipated the NASA-favored principle of “triple redundancy.” Crews united by a special “spirit of the expedition” excelled. He praised the Norwegian Fridtjof Nansen’s three-year journey into the Arctic, launched in 1893, for its planning, its crew selection, and its morale. One icebound Christmas, after a feast of reindeer meat and cranberry jam, Nansen wrote in his journal that people back home were probably worried. “I am afraid their compassion would cool if they could look upon us, hear the merriment that goes on, and see all our comforts and good cheer.” Stuster found that careful attention to habitat design and crew compatibility could avoid psychological and interpersonal problems. He called for windows in spacecraft, noting studies of submarine crewmen who developed temporarily crossed eyes on long missions. (The problem was uncovered when they had an unusual number of automobile accidents on their first days back in port.) He wrote about remote-duty Antarctic posts suffering a kind of insomnia called “polar big eye,” which could be addressed by artificially imposing a diurnal cycle of light and darkness.
“Bold Endeavors” was a hit with astronauts, who carried photocopied pages into space, bearing Stuster’s recommendations on workload, cognitive impairment, and special celebration days. (He nominated the birthday of Jules Verne, whose fictional explorers headed to the moon with fifty gallons of brandy and a “vigorous Newfoundland.”) But historical analogies could take NASA only so far, Stuster argued. Before humans went to Mars, a final test should run astronauts through “high-fidelity mission simulations.” To the extent possible, these tests should be carried out in some remote environment, whose extreme isolation would bring to bear the stress and confinement of a journey to outer space.
One morning in February, I was lurching through lava fields in a white Dodge Ram truck, halfway up Hawaii’s Mauna Loa volcano. Holding tight to the steering wheel, the driver, a University of Hawaii computer-science professor named Kim Binsted, told me that we were climbing the second-biggest mountain in the solar system. Mauna Loa is slightly shorter than its island neighbor Mauna Kea, but it is far more massive, rising gradually from deep below the surface of the Pacific to thirteen thousand six hundred and eighty feet above sea level. Binsted, who had a long side career in improvisational comedy, was soon quibbling with herself about the solar-system ranking—how to score the huge peaks in the Tharsis region of Mars?—but Mauna Loa’s claim is clearly impressive: if Earth were as dry as Mars, the mountain would rise nearly six miles from foot to summit. It is a slow-oozing shield volcano, like its Martian rivals, and the bleak terrain near the summit looks a lot like photographs of rough landscapes beamed from robotic rovers. The Johnson Space Center, in Houston, uses pulverized lava from its slopes to study potential agriculture in space colonies; its iron-rich basalt is a close analogue to the soil on Mars. As Binsted’s mentor, the NASA astrobiologist Chris McKay, put it, “Mauna Loa is our Martian mountain.”
Binsted stopped the truck where a chain blocked the red-cinder road and climbed out to open the lock. A sign said, “Isolation study in progress, please do not enter this area, or interact with the crew . . . Mahalo!” Beyond a rocky parapet near the eight-thousand-foot elevation, a two-story white vinyl geodesic dome came into view, perched on the mountainside like a gigantic golf ball sliced high into the rocks from a Kona resort. Multicolored lava fields fell toward the valley, where a thread of highway could barely be seen. Binsted asked me to whisper. Inside the dome, six volunteers were mimicking the life of astronauts on Mars for a NASA-funded test of team dynamics in space. They had been in the dome since October and would remain until June; at the moment, they were just a few days away from setting a North American record for a study of the effects of isolation and confinement.
Binsted wore a red polo shirt with the project’s logo: HI-SEAS, for Hawaii Space Exploration Analog and Simulation. Her short brown hair was barely cinched in a ponytail. As the principal investigator for the study, which is being run by the University of Hawaii, she had recruited and trained three men and three women, ranging in age from twenty-six to thirty-eight, preparing them for the austerities of travel to another planet. The dome is twelve hundred square feet, divided into a kitchen, an exercise area, and pie-slice sleeping quarters upstairs. Water is doled out as if it were being squeezed from the atmosphere by robots; each person is allowed eight minutes of shower time a week. The six crew members keep in touch with mission control only by computer, with a twenty-minute lag in each direction to simulate communication from Mars, and they leave the dome only on E.V.A.—extra-vehicular activity—wearing Velcro-sealed approximations of spacesuits. The crew members are engaged in small personal research projects and in team projects, mapping nearby geological features. All the while, they are themselves the subjects of the real research.
 Binsted, five feet six and briskly friendly, speaks with the intensity of someone who drinks a lot of Diet Coke. She was born in New Jersey and grew up near Vancouver in the nineteen-eighties, during the post-Apollo period, when public interest in space travel had abated. She studied artificial intelligence and got a doctorate at the University of Edinburgh, where she performed in her spare time with a troupe called the Improverts. For her thesis, in computational linguistics, she developed software that generated puns. (“What do you call a Martian who drinks beer? An ale-ien.”) Even then, she thought of her work as a way to connect to a longtime side interest in space. A friend of hers, the writer Sarah Rose, said, “The first time I met Kim, twenty years ago, she told me, ‘When the aliens come, I want to be the first person they call.’ ” Binsted noted, “ ‘They’ was the researchers, not the aliens. I just want to point that out.” A marathon runner, she applied five times to NASA’s astronaut-selection program and once to Canada’s (she holds dual citizenship), each time making it past the medical exams and reference checks and into the “highly qualified” pool. On her most recent attempt, in 2013, eight new astronauts were chosen from a field of sixty-three hundred, and Binsted was not among them. At the age of forty-three, she figured that she had finally aged out. “I stopped exercising the next day,” she says ruefully.
 The dome has a porthole, looking across the saddle at Mauna Kea—a legacy of the first study there, during which the benefit of a windowless exterior (protection from radiation) was found to be less significant than the drawback (the crew hated it). For our visit, the porthole had been covered over to keep the crew’s isolation complete. Quiet as parents on Christmas Eve, we ferried tubs of rice cakes and wet wipes from Costco into a back entry porch. Menus had been worked up during two previous missions in the dome, lasting four months each, during which food cooked ad libitum, even from reconstituted ingredients, rated much higher than the kind of meals-in-a-pouch necessary during zero-gravity travel. Back into the truck went black plastic bags of trash and boxes of saltines that had passed their shelf date. “ ‘Principal investigator’ sounds pretty glamorous,” Binsted said, as she climbed behind the wheel. “But a lot of what I do is space janitor.”
For years, NASA has run experiments replicating the environments of space and alien planets. Rovers and robotics have been tested in the Arizona desert and in the Canadian Arctic. “Human factor” studies in preparation for space-station duties have been carried out in a capsule at the Johnson Space Center and in an underwater lab off Key Largo. These days, the International Space Station provides an analogue for future long-duration missions; the astronaut Scott Kelly, who has just begun the first full year for an American in orbit, is the subject of psychological as well as physical tests. The Hawaii project represents another step for NASA: a test of group dynamics and morale to help design systems that will send a team into deep space.
Binsted and her colleagues sorted through seven hundred applications, winnowing them to a hundred and fifty serious candidates, many of them fit, well educated, and spunky—younger versions of Binsted. All six chosen for this round are aspiring astronauts, which makes them ideal subjects, Binsted said. They think more like modern space voyagers than did the sailors in earlier studies of isolation, but they are less wary and reticent than real astronauts tend to be. She wasn’t looking for volatile personalities, in the way of a reality-television producer; it was more like finding roommates to share an apartment. Astronauts tend to be resilient, low-drama types. On top of these qualities, she wanted sociability—a thick skin, a long fuse, an optimistic outlook, and a tolerance for low stimulation. The HI-SEAS crew includes an Iraq War veteran and microbiologist, a NASA aerospace engineer born in Azerbaijan, and a robotics graduate student who finished her degree and was named to Forbess “30 Under 30” in science while cooped up in the dome. In addition to their duties on sMars, as they sometimes call the simulation, they communicate with the outside world by blogging and posting photographs and videos. They are ferociously motivated, having already managed to cut their weekly shower allotment down to six minutes. The first time I e-mailed Martha Lenio, a thirty-four-year-old Canadian engineer who serves as commander, she mentioned in her reply, forty minutes later, that they wished they could get more feedback, even though it might undermine the study: “It’s a bit frustrating because we’re highly competitive and want to be the best crew.”
 The volunteers perched in the lava fields of Mauna Loa are as close as earthlings will get to Mars in the foreseeable future. In 2010, President Obama gave the mission a push, predicting that the nation would have a human in Mars orbit sometime in the twenty-thirties. There was something familiar about the upbeat rhetoric: since the nineteen-sixties, the schedule for a trip to Mars has been a shimmering, receding horizon, always a few decades away. Daunting technological, physiological, and political obstacles stand in the way of a project still so undefined that no real dollar figures are attached to it, although the figure of a hundred billion dollars is sometimes used to start a conversation. The National Research Council concluded last year that, without a focussed commitment, the U.S. has “no viable pathways to Mars,” and Congress is a difficult launching pad these days for major national initiatives. Contracts for commercial companies like SpaceX and Boeing to carry astronauts into orbit will help. On the other hand, the outlandish promises of private groups like the Netherlands-based Mars One—which has offered a one-way ticket to Mars for a bucket-shop rate, underwritten by a reality television show—may just feed the image of space exploration as a teen-age fantasy.
Yet the U.S. is actually somewhat closer to a Mars mission than it’s ever been. NASA is testing a new capsule and a new heavy-lift rocket. A robotic rover planned for 2020 will test technology for extracting oxygen from the Martian atmosphere. As John Logsdon, an emeritus professor at George Washington University’s Space Policy Institute, pointed out, “We’ve never cut hardware before.” A few weeks ago, Logsdon helped to convene a Washington, D.C., conference of scientists, industry representatives, and NASA staff which presented a “minimalist” plan, calling for a thirty-month human orbital mission to Mars in 2033, followed by a landing in 2039. It could be done, according to an advocacy group called the Planetary Society, at the current NASA funding level of eighteen billion dollars a year, growing with inflation—provided that funding is shifted to Mars from the International Space Station in the twenty-twenties.
 But, even in the best case, a human mission will be dauntingly expensive and dangerous—and once the astronauts sail past the moon they won’t even be able to talk to mission control in real time. Why not program robots to handle the whole job? Chris Kraft, NASA’s retired but still legendary cigar-clenching flight director, argued in a recent interview that the long delay in communication between Earth and Mars makes a human mission impractical. “As an operator, damned if I like that. If I’m on the moon, I’ve got a three-second turnaround. Everything I go to do on Mars I’ve got to prepare to do in an automatic mode. That’s not very smart. Pretty much everything we need to do on Mars can be done robotically.”
Proponents see it the other way around. Alain Berinstain, the former director of planetary exploration for the Canadian Space Agency and an adviser to Binsted, told me that the time lag was an argument against robots: “By the time you see that cliff coming, you’ve driven over it twenty minutes ago.” In contrast, an astronaut trained in geology can step onto the surface of Mars, look around, and pick up the one rock that makes a difference—and twenty minutes later ground control will hear about what she found. “It’s hard to say when, but we will go with humans to Mars,” Berinstain said. “It’s like humans exploring parts of the earth we didn’t know. We’re made that way.”
Some traditional ways of thinking about ground control and astronaut training will have to change. “With the Apollo program, every time a light went off you had a team of fifteen controllers telling you, ‘That light just went off, ignore it,’ ” McKay, the astrobiologist, told me. “When you go to Mars, the laws of physics just do not allow that. The ‘right stuff’ now is what’s required for a crew to work well in isolation. It’s a different set of skills. Some people won’t get it until we’re actually doing the mission. But there’s no way around it, unless they can change the speed of light.”
 The two most recent astronaut classes, in 2009 and 2013, were the first ones chosen explicitly with long-duration space missions in mind. The emphasis on more autonomy for crews has prompted a search for “different competencies,” NASA says. The best astronauts from the cool-test-pilot days of the Mercury program do not necessarily make the best crew for exploring deep space. But, with the right crew selection and planning, the thinking goes, the first step for man on Mars could turn out to be a giant group hug for mankind.
On Sophie Milam’s first E.V.A. in Hawaii, she had a panic attack. She is twenty-six, the youngest crew member, a former astronomy and physics student at the University of Hawaii campus in nearby Hilo. The task that day was to map a volcanic structure that might hold underground lava tubes. On Mars, such caverns could be useful for shelter in radiation storms. Crew members always wear fake spacesuits on E.V.A.s—mostly yellow hazmat suits that they consider “janky”—but Milam was wearing the good one, with a bubble helmet and fans inside. The suit weighs forty pounds, and Milam labored up a slope of crumbling lava, counting each step. Her teammate Jocelyn Dunn, a doctoral student from Purdue, said that spacesuits provide a pleasant singing-in-the-shower remove from the world. But Milam was thinking about how damp and warm it was inside and, as she wrote later on her blog, how the fans didn’t seem to be working:

Wait, I should feel wind on my face . . .
WHERE IS MY AIR?
stopStopSTOP
>calm down . . .
I can hear that nice calm voice but only barely over the overwhelming sound of PANIC
NO​AIRNOAIRNOAIR​GETTHISHELMET​OFFYOUCAN’T​GETOUTOFTHIS​SUITON​YOUROWN . . .
Milam had wanted to be an astronaut since she was five. She thought about that—“If you freak out too much they won’t let you go back out in this suit”—as she tried to relax and let the fans catch up. In her ear was the voice of her team partner Allen Mirkadyrov. She told him that she needed a minute to rest. She told herself that the air inside the suit was supposed to be different from the air outside: after all, they were on Mars.
Back inside the dome, after the mapping was completed, she was met by concerned teammates, who had heard heavy breathing on her voice-activated mike. They found a loose electrical connection in the air-intake system and fixed it. A few days later, she went back out in the suit, and soon was the team’s most eager volunteer for trips out of the dome. “Sometimes a girl just needs a spacesuit to feel like a real astronaut,” she wrote me.
“She was sort of getting back on the horse,” Martha Lenio, the group’s commander, said. Lenio grew up with the nickname Mars, but dropped it in the dome, because she kept thinking that people were talking to her. In real life, she is a renewable-energy consultant and has made it to the second round of the Canadian astronaut-selection process. One of the most satisfying parts of dome life, she told me, has been fixing things. The crew members devise projects, such as recycling dishwater through a filter of volcanic soil. They dub funny music into science-outreach videos for school groups. Milam, who was honored by Forbes for her work in nested-tetrahedron tensegrity robots, built a new spacesuit helmet out of duct tape, a pool noodle, and Bubble Wrap. She wrote on her blog, “When you’re trapped in a dome on the side of a volcano with five other nerds, you’d be surprised at how excited people get when you propose a fancy tinfoil hat.”
 Thus pass the weeks. The six compete to assemble “from-scratch” meals with freeze-dried ingredients, serving pho, sushi, gumbo, ravioli, and falafel. Exercise is built into their routine, as it would be for astronauts trying to maintain muscle mass in low gravity (Mars has three-eighths the gravity of Earth), and the chatty exhortations of Tony Horton, the self-described “fitness clown” who devised the P90X workout routine, permeate their conversations. The communication lag means no surfing the Internet, but Zak Wilson, who is twenty-eight, speculated that e-mail, even if it’s time-delayed, will help astronauts feel less isolated than old-time sailors trapped in the Antarctic ice. Wilson brought a 3-D printer, and as he finds himself casting about for useful items to make—iPad wall mounts, a Scotch-tape dispenser—he concedes that watching the extruder swing back and forth, depositing tiny bits of material with each pass, is “maybe not a terrible analogy for our stay here.”
 Eight months is a long time in a dome, but on a real voyage that’s when the crew might just be reaching its destination. The trip home could be significantly longer. Mars takes about twice as long as Earth to complete an orbit of the sun, and, as the orbits go out of phase, the distance between the planets ranges from thirty-five million miles to more than two hundred million. The designers of a mission face a difficult choice: stay on Mars for a year and a half, waiting for the planets to draw close enough for a quick trip home, or make a sixty-day stopover, which could mean a homeward journey of more than a year—drawing heavily on whatever stores of rocket fuel and human patience remain.
The HI-SEAS crew members have not been immune to homesickness, or to the pressures of monotony and enclosed space. Sometimes one will schedule an E.V.A. just to take a walk outside, or will sneak into the attached supply container to record a private voice mail. The days proceed with little variety apart from the sound of wind or rain on the dome. After passing the midway point, the crew started joking self-consciously about what researchers call the “third-quarter phenomenon,” when energy sometimes flags. Monotony and boredom can be a threat to any expedition’s well-being, as Jack Stuster documented with the Belgica. The mind grows stressed, and makes mistakes, as it searches for new stimulus. In the longest-ever space simulation, a five-hundred-and-twenty-day project in a Moscow warehouse that finished in 2011, lethargy caused withdrawal and perturbed sleep in some participants. The dangers of boredom can be especially acute during the long months of automated travel between planets—the narrative lull that drives screenwriters to do fantastical things with suspended animation and wormholes.
A little more boredom would have been welcome during an analogue study conducted in 1999 by the Institute of Biomedical Problems, in Moscow. A month in, on New Year’s Eve, a fistfight between two Russians left blood splattered on the walls. Minutes later, the crew commander forcibly kissed a female volunteer, a Canadian with a doctorate in health sciences. When she protested, she later recalled, the Russian scientific coördinator reported that she was ruining the atmosphere in the test module. Then she got head lice. A Japanese participant quit in protest. A decade later, when Russia launched its five-hundred-and-twenty-day study, to simulate a trip to Mars and back, all six participants were men. “I guess their solution to the problem of sexual assault was to not have women,” Binsted said.
None of the HI-SEAS crew saw anything surprising about mixing men and women on the crew. In space, women astronauts may have advantages. Kate Greene, a San Francisco writer who took part in an earlier HI-SEAS study, centered on food, mused on Slate about the possibility of an all-woman space crew, arguing that women tend to make a lighter load and to burn fewer calories for the same amount of work. Some researchers in Moscow’s 1999 study insisted that the problems came more from mixing nationalities than from mixing the sexes. But international mixing is likely to become even more common, given the need to share costs of travelling to deep space. Some planners have suggested running teams through remote analogues like the Mauna Loa habitat as a final test.
The only international tension reported in the dome this winter was over Allen Mirkadyrov’s preparation of khingal, served with a creamy dill sauce, which he assured his teammates was nearly as good as the version at the main Azerbaijani bus terminal. (Mirkadyrov, a naturalized U.S. citizen and Air Force veteran who works on orbital-launch vehicles at NASA’s Goddard Space Flight Center, grew up in Baku, Azerbaijan.) For the most part, the crew insists, time is passing quickly, with plenty of the morale-building activity recommended by Fridtjof Nansen: taco nights, competitive board games, group viewings of “Game of Thrones.” On Thanksgiving, the crew members lit up their biometric “actigraphy monitors” with two-step lessons.
Their persistently cheery e-mail updates raise a question: Does a happy crew tell NASA anything useful? Binsted argues that upbeat blog posts don’t always tell the whole story. Small gripes often emerge in the post-study interviews, when subjects know that their replies will be kept anonymous. It was only at the end of one of the four-month food studies in the dome, for instance, that Binsted heard from everyone about the “Nutella incident,” in which a crew member arrogantly finished off the group’s monthly ration, reasoning that the team was scheduled to open a new bin the next day. Stuster’s work with isolated crews found many examples of trivial annoyances growing unbearable, such as complaints from one of Byrd’s Antarctic crewmen about another man’s “way of breathing, his belief in dreams, and his frequent use of the phrase ‘I’m sorry.’ ” Stuster’s latest study for NASA, on private journals kept by astronauts, fairly hisses in places with steam let off by astronauts irritated by overscheduling, by patronizing requests, and by pointless-seeming tasks coming from ground control, such as recording serial numbers on items of trash. In the Mauna Loa dome, crew members simply roll their eyes when Binsted’s far-flung volunteer assistants do something lame, like expecting an immediate response to an e-mail sent when everyone is still asleep, because the sender forgot that sMars, like Hawaii, is not on daylight-saving time. Binsted calls it “crew-ground disconnect,” and deals with the problem in ways that are summarized by her use of the term “mission support,” rather than “mission control.” Her approach has worked, she said, “but we’ve kind of done it on the fly. We need to develop a flow chart and some acronyms, so that NASA can use it.”
 Even in a low-drama group, she says, there are bound to be moments: attacks of claustrophobia or arguments over dessert. “We know a lot about how to build bad teams and how to break good teams. Here we try to build the best teams we can, and support them as best we can, and find out when that’s not good enough.” How will such moments affect team performance? In space, a team that’s falling apart will probably be less effective. A team with too much cohesion might be prone to ignoring orders. Sometimes, Binsted will crank up the stress herself, as when she declared the approach of a radiation storm, forcing the crew to evacuate into a lava tube.
Measuring performance is relatively easy. It’s more challenging to find ways to measure, from a distance, how people are getting along. The crew members say that the worst part of the study is having to endure the stress and boredom of answering surveys—about forty each week—asking if they’re feeling stressed or bored. The fishbowl existence of their pet betta fish, Blastoff McRocketboots, seems carefree by comparison. The results from these surveys, along with cognitive tests and exit interviews, will be measured against data collected from biometric monitors and other devices worn by the volunteers. Readouts note the participants’ heart rates, voice levels, and even their proximity to one another. NASA hopes that the data from these and other high-tech mood rings will prove a reliable way to track how astronaut teams are doing without having to rely on self-reporting or on reading between the lines of an e-mail. The essence of the Hawaii experiment may be to make NASA more comfortable with sending crews out of close reach: if humans in space could be monitored a bit more like robots, mission control could spot an emotional cliff coming before the astronauts stumble over it. “Of course,” Binsted said, “there’s still the question of what interventions are actually available when your crew is on Mars.”
Two decades might seem like a long wait between a dress rehearsal and the performance. That’s what Chris McKay thought when he first heard about team-cohesion studies. For years, McKay led an informal national organization known as the Mars Underground, to keep conversation and research going when human deep-space voyages fell into disfavor. “At meetings, you would be ridiculed if you talked about searching for life on Mars. They would ask me, ‘Are you going to bring your butterfly net?’ ” He remains a leading astrobiologist at NASA, and he knows all the obstacles to getting to Mars. Sorting out crew issues didn’t sound like a big priority.
The earliest remote team tests seemed more about engaging the public than about testing systems for Mars. In 1997, a planetary scientist named Pascal Lee argued that his research camp in a vast meteorite crater on Northern Canada’s Devon Island—the largest uninhabited island in the world—would be an ideal place for NASA to model an expeditionary camp. In the end, two research stations operated on Devon Island: one for NASA-funded geological research and tests of spacesuits and rovers, and one for a nonprofit advocacy group called the Mars Society, which invited the Discovery Channel along. The Mars Society later started a second site, in the Utah desert—more accessible to the public and to the media. The desert simulations are short, and their contributions to space science have not been extensive. But, the Mars Society says, more than nine hundred people have taken part.
 One of those drawn to the Mars Society projects was Kim Binsted. In 2007, she signed on as the chief scientist for a four-month study on Devon Island—at the time, the longest Mars-analogue mission yet attempted. She was living in Hawaii, having moved there to teach after she launched and crashed a dot-com business in Tokyo. “In terms of stress, startups in Japan and academia in Hawaii pretty much define the spectrum,” she said. She figured that taking part in the analogue project might help her chance of becoming an astronaut.
The Mars Society habitat was not an exact replica of life on Mars, she found. When the crew went on E.V.A.s, one member armed with a rifle had to stay out of a spacesuit to watch for polar bears. Nor did it seem that enough thought had been given to crew compatibility. An expert on human performance in extreme environments who studied Binsted’s group reported that when conflicts arose the women tended to respond with “task coping” (finding a way to deal with the problem) while the men often reverted to “avoidance coping” (ignoring the problem “in favor of pursuing prolonged exploration while on E.V.A.s”). The study also cited reports of “unreciprocated sexual interest” expressed by a person of authority, and resentment from a French-Canadian participant who, forced by the group to sit through the television series “Lost,” complained that the plot was incomprehensible.
 Binsted enjoyed the experience, but figured that she could sharpen the concept. In addition to the “geologically relevant” red cinder, Hawaii’s lava beds would not require the down time of the Arctic in winter or the desert in summer. Experiments could be run sequentially, and rely less on anecdote. “The very nature of analogues is that they tend to be one-offs,” she said. “So if we see some things three times in a row we can say, Yeah, this is a thing.”
In 2012, Binsted and her colleagues received half a million dollars from NASA’s human-research program for the first, food-centered study in the dome. Since then, Binsted said, she has encountered occasional wariness from federal officials who are worried that they’ll be accused of encouraging Hawaiian junkets. The former Oklahoma Republican senator Tom Coburn included the food study in the 2012 edition of his government “Wastebook,” mocking the development of “out of this world” recipes for a mission that was decades away.
The project’s biggest obstacle came right at the start, when NASA informed Binsted that the grant could not be used for construction. Suddenly, she was two hundred thousand dollars short. When she went to the University of Hawaii looking for the sum, she found that the university had just lost exactly two hundred thousand dollars, to a sham promoter who pretended that he could bring Stevie Wonder to Honolulu for a concert. Binsted reached out instead to the only millionaire she knew who might care: Henk Rogers, who made a fortune in computer gaming—he holds licensing rights for the game Tetris—and once hosted a weekend gathering for space experts at his Big Island ranch. Rogers agreed to build the dome, and the food study got under way. A second NASA grant, for $1.2 million, followed, in 2013, calling for a series of three studies. The current one is the second; the crew’s record will fall when a twelve-month study follows theirs.
Pascal Lee, who is now drawing up plans for a NASA mission to the Martian moons of Phobos and Deimos, remains a little skeptical of team analogues that lack the stress and danger of a real mission. But he says that they serve an important secondary purpose: they inspire students, which he sees as essential to maintaining America’s leadership among the world’s spacefaring nations. “China landed a space rover on the moon, and within a decade will probably land a human being on the moon,” Lee said. “We pooh-poohed what China is doing. But we’re missing what that program is doing to science education in China. By the time we’re ready to go to Mars, our kids are going to be faced with this space superpower.”
McKay is now a believer for the same reason. “I have the zeal of the converted,” he said. In addition to providing an evangelizing tool, he thinks, the studies have raised useful questions, and this is a good time to ask them. “The technology is going to change,” he said, but “they’ll be the same humans as we have now.”
One evening in March, not long after the crew passed the four-month mark, Martha Lenio checked a wall-mounted iPad in the dome and saw an ominous descending line: the batteries were draining power instead of charging. Solar power is always scarce in the dome; to retain enough battery life for a normal night, the crew members cook dinner while the sun is still up. That week, through several days of rain and clouds, they’d been bundling up for warmth, boiling quick freeze-dried meals, and skipping movies at night. Even so, they’d run through their backup hydrogen cells, and they couldn’t get more gasoline for their generator—Binsted’s truck had broken down on her way back from a David Sedaris talk in Hilo—so they were running on their last jerrican. The triple-redundant system was failing. On Mars, such a scenario would put their life support at risk. The team made some emergency calculations. In a matter of hours, they would lose the fan on their composting toilet.
 Two crew members put on hazmat suits and went out with flashlights, waiting three minutes in the entry to simulate pressurization, but could find no problem. They went “out of sim” briefly, texting a mission-support technician for help troubleshooting, with no luck. So the crew came up with a plan. They shut off the lights in the dome and turned off the heat. They ran basic telemetry off the batteries and plugged an extension cord from the generator into their three highest priorities: the toilet fan, the refrigerator holding four months’ worth of frozen urine and saliva samples for NASA, and the tank heater for Blastoff McRocketboots.
In the morning, a technician drove up the mountain and fixed the generator. The crew remained inside, still buzzing from the change to their routine. “It was cold and dark, but it was also kind of fun to have a real challenge to step up to,” Lenio wrote on her blog.
Binsted told me that the crew members seemed to have performed well under pressure. “There was a lot of potential for crew-ground disconnect, and, although I’m sure they felt some frustration with mission support, they kept communications constructive and professional. They also managed to do a lot of troubleshooting and fallback planning on their own, which was impressive.” Given the difficulties of monitoring team dynamics from a distance, she said, she looked forward to seeing the data. “Maybe my perception is completely off!”
 A few days later, Lenio sent me a voice message. I had asked if she thought that people in her generation would ever walk on Mars. She told me that she thought they had a shot—or at least a shot at being alive when it happened. She pictured a crew like theirs, working under a red sky, building a habitat with very little margin for error. When she was a graduate student in Australia, she said, she got disoriented at night, because there was no Big Dipper and the moon was upside down. “I think those kinds of moments would happen to you all the time on Mars,” she said. “When you looked out the window, the sky wouldn’t be blue. You’d get that sense of awe all the time—new surprises every day.” In Hawaii, they were isolated and alone, on the side of an active volcano in the middle of the Pacific Ocean. But, as the power failure showed, it will be very different for the first settlers in outer space. “If life support goes down here, we’re not going to freeze to death, or we’re not going to lose all our oxygen. O.K., yeah, the habitat smells like crap, and the situation really sucks. But at the end of the day we don’t die.”

Former NASA chief on US space policy: “No vision, no plan, no budget”
 
Quote

During a congressional hearing Thursday, former NASA Administrator Mike Griffin had harsh words for the space agency—and the space policy crafted by President Obama's administration. Under the Obama administration's guidance, NASA has established Mars as a goal for human spaceflight and said that astronauts will visit the red planet by the 2030s. However, a growing number of critics say the agency’s approach is neither affordable nor sustainable.
On Thursday, Griffin, administrator of NASA from 2005 to 2009, joined those critics. The United States has not had a serious discussion about space policy, he testified, and as a result, the space agency is making little discernible progress. NASA simply cannot justify its claims of being on a credible path toward Mars, he added.
“To quote my friend and colleague Jim Albaugh, the now-retired CEO of Boeing Commercial Aircraft, the current administration’s view of our nation’s future in space offers ‘no dream, no vision, no plan, no budget, and no remorse,’” Griffin said during a hearing of the House Science Committee. “We must remedy this matter with all deliberate speed.”
The Republican chairman of the Science Committee, Lamar Smith of Texas, echoed those concerns in his comments, saying that under President Obama, NASA does not seem to be taking a serious approach to human exploration. The hearing comes at a critical time for NASA, now two months into the last year of President Obama’s second term and with a new administrator likely to replace Charles Bolden in 2017. Republicans in Congress have made it clear they do not favor the president’s plan to send astronauts to visit a fragment of an asteroid near the Moon and an eventual journey to Mars.
In fact, legislators appear to support returning to the Moon as a stepping stone en route to exploration deeper into the solar system. That was evident by the choice of witnesses for the hearing, including Griffin, who strongly called for a US-led international partnership to develop a permanent human presence on the Moon.
Another witness, retired astronaut Eileen Collins, echoed what most current and former astronauts also appear to believe: that the Moon is a good training ground for missions deeper into space. As a pilot and commander of multiple space shuttle missions, she said most of her colleagues favor such an incremental approach. “When asked about how best to prepare for a successful Mars mission, as a crew member, I certainly would like to see the hardware tested on the Moon’s surface first,” Collins testified. “This is part of a test plan’s build-up approach. Policy leaders are asking astronauts to risk their lives on space journeys, and it is our experience that testing in similar environments will minimize risk.”
The overall purpose of Thursday’s hearing was to discuss leadership and stability at NASA, which often sees a policy whiplash every four to eight years when a new president comes into the White House. That certainly was the case in 2009, when President Obama turned NASA away from Griffin's choice of the Moon toward the asteroid belt and an eventual Mars mission.
However NASA’s partners on the International Space Station have been slow to embrace this move. During the last year, European Space Agency Director General Johann-Dietrich Wörner has in fact broken from NASA by speaking of establishing a “Moon Village.” A growing number of US companies are interested in supplying such an effort and using a lunar base to mine for ice and other resources. These resources might then serve as a cache of fuel and other supplies for exploration to Mars.
To bring stability, Rep. John Culberson (R-Texas), has proposed legislation (
HR 2093
) that he says would make NASA more professional and less political. The bill would appoint a NASA administrator for 10 years instead of having him or her serving at the behest of the president. It would also reduce the influence of the White House Office of Management and Budget on space policy by having NASA’s board of directors submit a budget request directly to Congress.
During the hearing on Thursday, Culberson noted that NASA has spent $20 billion on canceled spaceflight programs and that this has proved very damaging to morale at Johnson Space Center in Houston as well as other field centers. “We need to ensure that we take the politics out of science and provide NASA with clear direction and guidance that outlasts the political whims of any one presidential administration—and the political whims of Congress,” Culberson said.
Culberson’s predecessor as chairman of the House Appropriations subcommittee with oversight of NASA’s budget, Frank Wolf, also proposed similar legislation before. It did not advance. The new bill may suffer the same fate, but Thursday’s hearing clearly demonstrated Congressional dissatisfaction with NASA’s current human spaceflight efforts.
Although space has not been an issue during the presidential primary process and is unlikely to bubble up during the general election, it seems that the next president and an unhappy Congress will have quite a bit to say about the direction NASA takes in 2017. At this point, that direction looks to include a more serious reassessment of the Moon as a proving ground for deeper exploration.

A year in space really messed up astronaut Scott Kelly
 
Quote

Space does not necessarily do a body good.
NASA astronaut Scott Kelly, who will complete a 340-day mission aboard the International Space Station Tuesday night, is expected to be scrawnier, weaker, and have worse eyesight than when he lifted off, scientists predict.
The 52-year-old spaceman from New Jersey will undergo a series of physical and medical tests as soon as the Soviet-designed Soyuz spacecraft carrying him lands in Kazakhstan on Tuesday around 11:27 p.m. Eastern time, according to The Verge.
Kelly is the first American to spend more than 11 months in microgravity, and once hes lands safely, scientists will focus on its effects on the human body.
The most obvious and expected change that officials believe they will see is a significant loss of muscle mass and bone density, since Kelly’s body did not have to work against gravity while aboard the space station.
NASA also expects Kelly to experience extreme dizziness, and even fainting, upon his return — due to the fact that blood and other fluids will collect in the upper body during extended stays in space and rush back down to the legs once back down on Earth.
Another side effect will be altered vision and poorer eyesight, something Kelly noted in a recent press call from space, the site reported.
Astronauts returning home will often have swelling behind their eyes — which may be caused by a buildup of fluid in the head, according to Jennifer Fogarty, who is chief of NASA’s Space Life Sciences program.
In addition, NASA predicts that Kelly will suffer from drastic changes to his immune response and digestive system — since he’s been eating nothing but space food for the last year.
Officials expect his gut microbiome to be altered completely when he arrives back on Earth — and research shows that living on the ISS may have even changed how the bacteria in Kelly’s stomach express RNA, the genetic messengers that control the behavior of cells.
“Some bacteria may become more potent when they’re in space,” National Space Biomedical Research Institute vice president Graham Scott told the Verge.
Once Kelly is back home, scientists will take samples of his blood, fecal matter, urine and saliva and compare them to samples from his identical twin brother, Mark, who is also an astronaut.
The agency will analyze the samples closely and try to determine which of Kelly’s health changes were a result of living in space and which were induced by genetic predisposition.
Over the next few months, they will also take a close look at Kelly’s mental state, which Fogarty says has so far been great.
The whole purpose of NASA’s “One-Year Mission” was to help experts better understand the side effects of living in space, so they can start prepping crews for missions to Mars one day.
NASA says Kelly’s test results may take up to six years to be published.
Once the agency stops performing tests on him, Kelly said that one of the first things he plans to do is go home and jump in his pool.

Još malo o Skotu Keliju (strašno da o njemu kopiram vesti iz NY posta koji je njujorška verzija Alo!-a al šta da se radi...):
 
 
 
 For Scott Kelly, being back on Earth isn’t all it’s cracked up to be
 
Quote

CAPE CANAVERAL, Fla. — Fresh from a year in space, NASA astronaut Scott Kelly said Friday his muscles and joints ache. His skin is so sensitive it burns when he sits or walks. And he can’t sink a basketball shot.
He’s surprised — not necessarily about his basketball skills, but everything else. After his previous half-year space station mission five years ago, he wasn’t nearly this tired or sore.
“Adjusting to space is easier than adjusting to Earth for me,” he said at his first postflight news conference Friday.
Like other astronauts, he got taller in space. He said he gained 1½ inches. But he lost it almost as soon as he stood on solid ground.
Kelly returned from the International Space Station on Wednesday, ending a 340-day mission that set a U.S. record. It took him a full day to get back home from the landing site in Kazakhstan to Houston. That’s when the aches and pains set in — this from the guy who hopped out of his space capsule and later promptly jumped into his backyard pool.
Initially, he felt better than last time, but that quickly changed.
The 52-year-old astronaut said because his skin hasn’t had significant contact with anything for so long — in space, clothes just float around you — “it’s very, very sensitive. It’s almost like a burning feeling wherever I like sit or lie or walk. I’m not wearing these shoes all the time,” he said, kicking up his right foot, which sported a shiny black dress shoe. “I just wore them for you guys.”
Thick running shoes are his preference these days; they make his feet “feel a little bit better.”
As for the culture shock of being back on Earth, Kelly expects that will hit soon. “From having so little on the space station and so few choices about what you’re going to do every day, what’s available to you, to basically having just about anything,” he told reporters.
His first food back on Earth? A banana he found on his bed aboard the plane. He didn’t realize the irony until he ate half of it; he cavorted around the space station a few weeks ago in a gorilla suit, a gag gift from his identical twin, Mark, a retired astronaut.
The genetic doubles — one in space, one on the ground — took part in medical studies throughout the flight. NASA wants to know how the body and mind adjust to long periods in space before sending astronauts to Mars; expeditions are planned for the 2030s.
NASA’s chief space station scientist, Julie Robinson, said she’d ideally like 10 or 12 astronauts to spend extra-long periods in space to know what all the risks might be.
Johnson Space Center physiologist Dr. John Charles said he was impressed Kelly managed to complete all his physical exercises — standing up suddenly, walking heel-to-toe, navigating an obstacle course — immediately after touchdown. He’d likely fare well on Mars, scrambling to get out of a spacecraft on his own, taking a fast spacewalk and settling in, according to Charles and Mark Kelly.
“He’d be a good example of somebody who could probably make that trip to Mars for six months and then in a short period of time, do some reasonable work,” observed Mark Kelly. Round trip, a Mars mission would last 2½ years.
Kelly’s companion for the entire space journey, cosmonaut Mikhail Kornienko, 55, is back home in Star City, Russia, dealing with his own adjustments to gravity.
Many of their blood, urine and saliva samples are still up on the space station, frozen. NASA must wait until its commercial shipper SpaceX is delivering back and forth again — following a launch accident last summer — to get the scientific treasure trove, hopefully in May. Charles expects it will take the next year to analyze all the data.
During his year in space, Kelly sent back dazzling photos of Earth and chronicled his space days on Twitter, attracting more than 1 million followers. He partnered with his girlfriend, Amiko Kauderer, a public affairs representative at Johnson, to set social media ablaze.
Kelly holds the U.S. record for total days in space — 520 days over four missions. He doubts he’ll fly again for NASA. But perhaps in the next 20 years, “you’ll be able to just buy a cheap ticket, go for a little visit.”
“I’ll never be done with space,” he said. “I will always be involved.”

NASA examines options and flight paths for SLS EM-2 mission



Quote
As NASA and its contracted partner agencies press forward toward the debut launch of the Space Launch System (SLS) rocket in 2018, the U.S. space agency is beginning to look toward preliminary planning and test objectives for the EM-2 mission of the SLS Program, which is expected to take place sometime in the opening half of the 2020 decade.
The road to EM-2
As originally conceived in the opening years of the SLS program, the EM-2 mission was to be the first crewed flight of the Orion Multi-Purpose Crew Vehicle that would take astronauts on a multi-day circumlunar mission.




However, the feasibility of this mission being one to carry crew was called into question as the EM-2 launch date slipped beyond the opening of the 2020 decade and NASA began investigating the potential advancement of the introduction of the Exploration Upper Stage (EUS) from the third to the second EM flight of SLS. 
Originally, with timelines indicating that EM-2 would follow a couple years after EM-1, it was understood that EM-2 would make use of the same Interim Cryogenic Propulsion Stage (ICPS) as EM-1- with one key difference: The ICPS would be human rated for EM-2.
The feasibility of this was quickly challenged as the ICPS’ human rating would cost millions of dollars (USD) for a single-mission event before the switch to the EUS on EM-3 and all subsequent SLS flights.
Nonetheless, the human-rated ICPS for EM-2 would satisfy the requirement from the astronaut office that no crew fly on any variant of the SLS rocket when a major propulsion element was being used for the first time in flight.
However, NASA’s decision to advance the introduction of the EUS to EM-2 created a conflict with that rule – as EM-2 was viewed in its initial conception as the second flight of SLS, thus leaving no room between the EM-1 and EM-2 missions of SLS to test the EUS in flight.
The FY 2016 U.S. federal budget
However, following a protracted budget battle – which has become all too usual for the U.S. Congress – the final FY 2016 federal budget included language specifically addressing the Europa Clipper Mission and the vehicle upon which it would launch.




Originally, the notional mission to Europa was tentatively penciled in for launch aboard an Atlas V 551 variant from the Cape Canaveral Air Force Station. 
However, the FY 2016 U.S. federal budget for NASA specifically directed funding “for the Jupiter Europa clipper mission and clarifies that this mission shall include an orbiter with a lander that will include competitively selected instruments and that funds shall be used to finalize the mission design concept with a target launch date of 2022.”
More surprisingly, the FY 2016 federal budget language also specifically mandated the vehicle upon which Europa Clipper will launch.




“The National Aeronautics and Space Administration shall use the Space Launch System as the launch vehicle for the Jupiter Europa mission, plan for a launch no later than 2022, and include in the fiscal year 2017 budget the 5-year funding profile necessary to achieve these goals.”
With SLS now legally mandated as the launch vehicle for Europa Clipper, the issue of testing the EUS in-flight prior to EM-2 could be rectified if SLS launches the Europa Clipper mission in 2022 ahead of EM-2.
This would place the EM-2 mission firmly in the No Earlier Than 2023 timeframe, approximately five years after the EM-1 mission, currently on track to launch by “No Later Than November 2018,” according to the Exploration Systems Development (ESD) presentation to the NASA Advisory Council Meeting on 2 March 2016.
EM-2 planning begins:
Despite uncertainty to the exact timeframe of EM-2, NASA has begun formal planning operations for the flight.




“Mission planning for EM-2 and beyond including on-ramp for low-cost opportunities for development tech objectives and capability enhancements” are underway, notes the ESD presentation.
Moreover, a dedicated mission planning team has been established, co-manifest payload options are being evaluated, and a mission planning resources watch item list is being created.
Critically, on-orbit Micro-Meteoroid and Orbital Debris (MMOD) risk exposure and related mission profile/trajectory planning efforts for the first crewed flight of SLS and Orion are in the initial phases of study, as are the precise objectives the EM-2 crew will achieve during their multi-day flight around the moon.



According to the ESD presentation, “With the selection of the EM-1 Mission being a DRO (Distant Retrograde Orbit) mission the goal of EM-2 is [to] complete residual FTOs (Flight Test Objectives) not accomplished on EM-1 [and] accomplish risk reduction activities for future more complex missions for EM-3+.”
(A DRO is a highly stable orbit that exists due to the interaction between the Earth and Moon’s gravity.)
Notably, the ESD presentation notes that EM-1 and EM-2 “should include capabilities relevant to potential near term deep-space missions.”
To this end, both EM-1 and EM-2 are classified as Design Reference Missions (DRMs), intended to be “design driving cases … to maintain current SLS/Orion FTOs while demonstrating as many Exploration Objectives as cost, schedule and risk allows.”
EM-2 flight options, in-flight abort requirements:
Presently, EM-2 is baselined as a High Lunar Orbit (HLO) mission.
Of particular note and importance for EM-2 is the fact that the vehicle will carry, at every point in its mission, the ability to directly return its crew to Earth within five days should such an emergency situation arise.



Additionally, according to the “Evolution of Orion Mission Design for Exploration Missions 1 and 2” report, Orion and its crew, through the Trans-Lunar Injection (TLI) burn, will be placed into a free return trajectory to a nominal Earth Entry Interface condition. 
This specific free return trajectory will allow the crew to safely return to Earth in the event the Service Module’s (SM’s) engine fails to ignite post-TLI.
In this case, in a free return trajectory, a minimal series of thruster burns can accomplish precise positioning of Orion to allow for a passive swing and gravity assist maneuver around the Moon to slingshot the vehicle and crew back toward a landing point on Earth without any major burns.
Baselined HLO mission:
Under this profile, Orion and the EM-2 crew would launch aboard SLS and complete one full orbit of Earth before the TLI burn on the second orbit would propel them toward the Moon.
After jettisoning the EUS, the SM would perform the Outbound Trajectory Adjust (OTA) burn to lower the lunar flyby altitude to 100 km (62.13 miles).




Orion and its crew would then coast through the void between the Earth and the Moon before swinging around the backside of the Moon.
This baseline would see the crew and vehicle perform a Lunar Orbit Insertion (LOI) burn at an altitude of 100km above the lunar surface to enter a 100 x 10,000 km (62.13 x 6,213.712 miles) HLO trajectory.
After three days in lunar orbit, the Trans-Earth Injection (TEI) burn would propel Orion and its EM-2 crew into a return trajectory back to Earth to wrap up an approximate 9-13 day mission.
However, NASA is also evaluating two other options for the flight path and trajectory the EM-2 flight could take.
EM-2 Option 1 – DRO/NRO
Under this option, the EUS stage would be used to deliver Orion and a four-person crew into a DRO DRM flight.
In this manner, EM-2 would repeat the EM-1 DRO trajectory, only this time it would carry a crew through those maneuvers and flight path.




Additionally, NASA could also choose to send EM-2 to other destination orbits such as the L2 Halo, a Near Rectilinear halo Orbit (NRO), or a high-energy cislunar orbit that long-duration habitat missions might experience. 
Under this mission option, the “Evolution of Orion Mission Design for Exploration Missions 1 and 2” report states that the increased performance gained from the use of an EUS on EM-2 could allowed for a co-manifested payload in the form of additional consumables to allow Orion and its four person crew to perform a mission greater than the 21 day limit currently afforded to the spacecraft.
This kind of DRO mission would result in a total mission duration of 25-26 days, so additional consumables would be needed assuming NASA opted to go with a maximum crew size of four.
EM-2 Option 2: Hybrid
However, since EM-2 will be the first Orion mission to carry people, the “Orion Mission Design” report notes that “the Orion Program and NASA may choose to fly a mission that is less risky in some aspects.”



The exact meaning of “less risky” could range from a desire to fly a path that conserves propellant for contingency abort cases to opting to fly a trajectory that avoids HLO and allows the crew to return to Earth faster than an HLO flight path would permit.
Under this consideration, a hybrid mission for EM-2 would preserve some elements of an HLO DRM flight and reject others.
This kind of mission would see the crew launch into three different Earth elliptical orbits.
The first orbit would be close-range, with a first-orbit-complete-perigee engine firing from the EUS to raise the craft’s orbit to 391 x 71,333 km (242.9 x 44,324.3 miles).




After this burn, Orion and its SM would separate from the EUS.
This second orbit of Earth would carry a total orbital period of 24 hours and would allow the EM-2 crew to fully vet and check their spacecraft and its systems before committing to the swing around the moon.
During this 24 hour orbit, if a system does not check out, Orion and EM-2 can remain in this orbit until the situation is resolved.
Conversely, if a serious issue develops while in this 24 hour orbit, Orion can return the EM-2 crew to Earth within 12 hours.
However, if all systems check out, Orion’s SM engine would, at a perigee of 391 km, fire for the TLI burn and propel EM-2 toward the moon.
This TLI would put Orion and EM-2 on a “near-free return trajectory,” notes the “Orion Mission Design” report, and would result in a swing through the lunar L2 point.




Concretely, it would result in Orion and EM-2 performing a lunar flyby at the L2 point at a distance of 61,548 km (38,244.15 miles) from the lunar surface.
At this point, Orion’s SM engine would perform the Return Trajectory Adjust (RTA) burn with a deltaV of 77 m/s (253 f/s) to aim the craft for the location Earth will be at for Entry Interface and landing.
This Hybrid mission would last approximately 15-16 days and would carry an added risk of radiation and MMOD as Orion would make multiple passes through the Van Allen Radiation Belts and Earth proximity space.
However, the “Orion Mission Design” report notes that the “radiation dosage to the crew for two revolutions in the intermediate orbit is roughly equivalent to a six-month stay on the ISS.”

SpaceX Delivers World's 1st Inflatable Room for Astronauts



Quote
SpaceX has made good on a high-priority delivery: the world's first inflatable room for astronauts.
 A SpaceX Dragon cargo ship arrived at the International Space Station on Sunday, two days after launching from Cape Canaveral. Station astronauts used a robot arm to capture the Dragon, orbiting 250 miles above Earth.
 The Dragon holds 7,000 pounds of freight, including the soft-sided compartment built by Bigelow Aerospace. The pioneering pod — packed tightly for launch — should swell to the size of a small bedroom once filled with air next month.
 It will be attached to the space station this Saturday, but won't be inflated until the end of May. The technology could change the way astronauts live in space: NASA envisions inflatable habitats in a couple decades at Mars, while Bigelow Aerospace aims to launch a pair of inflatable space stations in just four years for commercial lease.
 For now, the Bigelow Expandable Activity Module — BEAM for short — will remain mostly off-limits to the six-man station crew. NASA wants to see how the experimental chamber functions, so the hatch will stay sealed except when astronauts enter a few times a year to collect measurements and swap out sensors.
 This is SpaceX's first delivery for NASA in a year. A launch accident last June put shipments on hold.
 SpaceX flight controllers at company headquarters in Hawthorne, California, applauded when the hefty station arm plucked Dragon from orbit. A few hours later, the capsule was bolted securely into place.
 "It looks like we caught a Dragon," announced British astronaut Timothy Peake, who made the grab. "There are smiles all around here," NASA's Mission Control replied. "Nice job capturing that Dragon."
 SpaceX is still reveling in the success of Friday's booster landing at sea.
 For the first time, a leftover booster came to a solid vertical touchdown on a floating platform. SpaceX chief executive Elon Musk wants to reuse boosters to save money, a process that he says will open access to space for more people in more places, like Mars. His ambition is to establish a city on Mars.
 NASA also has Mars in its sights and looks to send astronauts there in the 2030s. In order to focus on that objective, the space agency has hired U.S. companies like SpaceX to deliver cargo and, as early as next year, astronauts to the space station. U.S. astronauts currently have to hitch rides on Russian rockets.
 In a sign of these new commercial space times, a Dragon capsule is sharing the station for the first time with Orbital ATK's supply ship named Cygnus, already parked there two weeks. This is also the first time in five years that the compound has six docking ports occupied: Dragon, Cygnus, two Russian Progress freighters and two Russian Soyuz crew capsules.
 The Dragon will remain at the station for a month before returning to Earth with science samples, many of them from one-year spaceman Scott Kelly. He ended his historic mission last month. Cygnus will stick around a little longer.

Space Race: Astronaut Runs London Marathon — From ISS



Quote
British astronaut Tim Peake became the first man to complete a marathon in space on Sunday, running the classic 26.2 mile distance while strapped to a treadmill aboard the International Space Station.
 As part of the London Marathon, Britain's biggest mass participation race, the 44-year-old spaceman saw London's roads under his feet in real time on an iPad as, 250 miles below him, more than 37,000 runners simultaneously pounded the streets.
 Peake covered the distance in three hours 35 minutes 21 seconds, which was a world away from the time recorded by the real race winner, Kenya's Eliud Kipchoge, whose 2:03:05 was the second fastest ever recorded.
 Peake's zero gravity effort, while out of this world, was still more than a quarter of an hour slower than the 3:18:50 he had clocked on earth as a keen, ultra-fit fun runner back in 1999.
 On a six-month stint on the ISS, the astronaut had been the official starter too, sending the runners a good luck video message from the station in the 10-second countdown to the race that concluded: "I hope to see you all at the finish line."
 He also tweeted a photograph of England's capital from space accompanied by the message: "Hello #London! Fancy a run? :)".
 Then, it was down to business, using elastic straps over his shoulders and around his waist to keep him in contact with the running belt in weightless conditions as he ran.

NASA awards companies $65 million to develop habitats for deep space 
 
Quote

NASA is serious about going to Mars, and not just for a quick visit, either. It just committed $65 million, spread over two years and six companies, for the purpose of developing and testing deep-space habitats that could be used on the way to — and on the surface of — the Red Planet.
It’s part of the organization’s NEXTStep (not to be confused with the NeXTSTEP OS), an ongoing partnership program under NASA’s Advanced Exploration Systems that funds private research into technology for space exploration.
Last year’s NEXTStep contracts were for a variety of things, but this year they’re all on the same track: “deep space habitats where humans will live and work independently for months or years at a time, without cargo supply deliveries from Earth.” We’re talking spaceships here — big ones.
The numbers are bigger, too: the previous year’s contracts amounted to a total of perhaps $15 million divided 10 ways — $65 million 6 ways is, it hardly needs saying, a much more considerable investment.
The lucky companies are all taking slightly different approaches to the problem of deep space habitation.
 
Bigelow is a name you may already be familiar with: the Bigelow Expandable Activity Module was recently attached to the International Space Station and is currently undergoing testing. The company plans to develop one about 20 times larger (330 vs 16 cubic feet) that they call the Expandable Bigelow Advanced Station Enhancement, or XBASE. There are advantages to being able to pack your modules tightly and expand them later, but the BEAM’s troubled deployment shows there are challenges as well. Of course, that’s what testing is for.
Lockheed Martin doesn’t want to let good space gear go to waste, either; its plan is to refurbish one of the cargo modules carried by the Space Shuttles into a livable multi-purpose environment. The idea is, essentially, to use proven equipment as a base to test future developments, like data and crew transfer between the module and, say, the Orion spacecraft.
Another avid recycler is NanoRacks, whose commercial experimentation platform outside the ISS just went live yesterday. Nanoracks has a rather crazy idea: convert the final rocket stage, with its spacious fuel compartment, into a habitable space. It’s working with Space Systems Loral and the United Launch Alliance to see if this is crazy enough to work — or just plain crazy.
Sierra Nevada (specifically its subsidiary Space Systems) has perhaps the most ambitious plan. Over four commercial launches, the company wants to build on one of its Dream Chaser cargo modules, adding a propulsion system, an expandable environment, and life support. Taking it in stages means better risk management.
Boeing and Orbital ATK didn’t provide many details: the former just says it’s building a full-scale prototype for extensive testing, and the latter is adapting one of its Cygnus spacecraft to the purpose.
It’s all very early, of course, and these projects, among others, are for exploring possibilities and finding potential problems, not actually producing something we can send to Mars or beyond. The technology investigated by these companies will have to prove itself on the ground first, then in orbit, and eventually in cislunar space — the “proving ground” for long term mission hardware.
NASA didn’t specify how much each project was receiving, or the exact timelines or deliverables expected from each — although results are certainly expected by the time the contracts’ 24 months are up. I contacted NASA for more details and will update this post if I hear back.

China's Shenzhou 11 blasts off on space station mission



Quote
China has launched two men into orbit in a project designed to develop its ability to explore space.
The astronauts took off from the Jiuquan Satellite Launch Centre in northern China.
They will dock with the experimental Tiangong 2 space lab and spend 30 days there, the longest stay in space by Chinese astronauts.
This and previous launches are seen as pointers to possible crewed missions to the Moon or Mars.
An earlier Tiangong - or Heavenly Palace - space station was decommissioned earlier this year after docking with three rockets.
The astronauts on this latest mission were Jing Haipeng, 49, who has already been to space twice, and 37-year-old Chen Dong.
