ZNAK SAGITE — više od fantastike — edicija, časopis, knjižara...

Nije vezano za Kjuriositi, ali je vezano za Mars i život na njemu. Naime, ako pretpostavimo da je na Marsu bilo života i da je bio dovoljno sličan zemaljskom (što bi dalje pretpostavilo zajednički izvor) da ima DNK, onda neki sledeći robotski istraživač Marsa može da nosi sa sobom DNK sekvencer, pronađe ostatke DNK, analizira sekvencu i pošalje je na zemlju gde onda u laboratoriji može da se inženjerskim, jelte, radom, kreira, da ne kažem klonira Marsovac. To je bar, hm, teorija:

Life on Mars? Scientists hope to find it by decoding Martian DNA 

Quote
  Apparently, there just aren't enough genomes for Craig Venter to sequence here on Earth, so he's making plans to send a DNA sequencer to Mars.
"There will be life forms there," Venter said, with his usual confidence, at a Wired Health conference this week in New York.
If he can build a machine to find it, the next steps would be to decode its DNA, beam it back to Earth, put those genetic instructions into a cell and then boot up a Martian life form in a biosecure lab.
It may sound far-fetched, but assuming that there is DNA to be found on the Red Planet – a big assumption, to be sure – the notion of equipping a future Mars rover to sequence the DNA isn't so crazy.
Venter has already sent his yacht around the globe to scoop up seawater and sequence whatever DNA it found in marine microbes. He has also been working on technology to create small genomes from scratch and insert them into living cells to bring these organisms to life. The difference now is that all of this technology would be applied to Mars.
It's highly unlikely that any DNA-based life forms could survive on the Martian surface, so Venter's "biological teleporter" (as he dubbed it) would dig under the surface for samples to sequence. If they find anything, "it would take only 4.3 minutes to get the Martians back to Earth," he said. "Now we can rebuild the Martians in a P4 spacesuit lab."
Venter isn't the only one looking for Martian DNA. According to this report in MIT's Technology Review, so is Jonathan Rothberg, founder of the genome sequencing company Ion Torrent.
Rothberg is working with NASA-funded scientists from MIT and Harvard to adapt his company's Personal Genome Machine for use on Mars, the report says. It's part of a NASA astrobiology project known as the Search for Extra-Terrestrial Genomes, or SETG.
MIT research scientist Christopher Carr is part of a group that's "building a a miniature RNA/DNA sequencer to search for life beyond Earth," according to his website. "Top places to look include Mars, Enceladus [a moon of Saturn], and Europa [a moon of Jupiter]."
Carr told Tech Review that one of the biggest challenges is shrinking Ion Torrent's 30-kilogram machine down to a mere 3 kg – light enough to fit on a Mars rover.
That's just one of the hurdles. NASA has no firm plans for a rover to succeed Curiosity, the lab-on-wheels that reached the Red Planet in August. Even if a new rover gets the green light, there's no guarantee that a gene sequencer would get one of the coveted spots for research instruments.
There's more on this plan on the Tech Review website. You can watch Venter explain his plan at the Wired Health conference here (beginning at around the 11-minute mark).

NASA's "History Book"-Worthy Discovery Is Really Just a Big Misunderstanding

Quote
Well, this is a letdown.
  Remember last week when we told you about how NASA's Curiosity rover had reportedly sent back some very interesting data from Mars in the form of a soil sample that could be, in the apparent words of one of the mission's leaders, "one for the history books"? Yeah, well, now NASA is saying that all the hype is actually just a giant misunderstanding between the scientist and the NPR reporter who interviewed him—a mistake that was then multiplied many times over by each news outlet (again, including us) who picked up the story.
  Here, let's have Mashable, which did the legwork to follow up on the original NPR report, explain (emphasis ours):
 

The quote heard around the world came shortly after [scientist John] Grotzinger explained that NASA had just received the initial data from Curiosity's first soil experiment using a new Sample Analysis at Mars (SAM) instrument, which is capable of identifying organic compounds.

 

Naturally, the public assumed that this meant Curiosity had discovered a complex organic molecule. But while NASA does have the latest soil samples, the mission team tells

Mashable that researchers haven't determined that particular groundbreaking discovery. ...

 

What Grotzinger was actually trying to convey is that Curiosity's data over her entire two-year mission will further our knowledge of Mars more than ever before, making it a historical mission.

  So to recap, Grotzinger was apparently trying to express just how excited he was about the entire mission, not about any one specific discovery; it is the sum of all of Curiosity's past and future discoveries that he thinks will be historic. His particular choice of words—"This data is gonna be one for the history books"—however, along with the suggestion that his team was currently double- and triple-checking data it had received (something that is standard procedure) gave NPR the mistaken impression that there was something specific that NASA was eager to celebrate as a major discovery.
  The original NPR report made it pretty clear that the reporter doing the interview, veteran science correspondent Joe Palca, thought Grotzinger was hyping a specific result:
 

Grotzinger says they recently put a soil sample in SAM, and the analysis shows something remarkable. "This data is gonna be one for the history books. It's looking really good," he says.

 

Grotzinger can see the pained look on my face as I wait, hoping he'll tell me what the heck he's found, but he's not providing any more information.

  While it's a little odd that NASA's communication team didn't manage to quickly quash the rumor after the original report aired, Veronica McGregor, NASA's news and social media manager for the Jet Propulsion Laboratory, told The Slatest late Tuesday night that they did their best to set the story straight.
  The day after the story first aired, the team used Curiosity's official Twitter account to tweet: "What did I discover on Mars? That rumors spread fast online. My team considers this whole mission 'one for the history books'." That message, however, was largely lost in cyberspace over the long holiday weekend, possibly in small part because the account often strikes a somewhat whimsical tone. But McGregor told us that NASA was also sure to pass along the correct info to any media outlet that inquired about the quote in question.
  As for how the original misunderstanding happened in the first place, McGregor explained:
 

"The short story is NPR was there when the first soil results were hitting the ground and the team was ecstatic to see data. Could they analyze that data on the fly and give an accurate result? No. In fact, they've spent a good part of two weeks sorting through the data in order to reach conclusions based on solid science."

  Regardless of whether you're willing to buy into a conspiracy theory (and let's be honest, this is NASA, so some people will), it's pretty clear that anyone hoping for major news of the type originally suggested will have to keep waiting for now. Grotzinger and his team are set to discuss their latest findings on Monday at a meeting of the American Geophysical Union in San Francisco, but a NASA spokesman tells the New York Times that those findings will be "interesting" rather than "earthshaking."  A version of this post was first published on Tuesday at 6:01 p.m.   

Ali za utjehu: ima vode na Merkuru!

NASA Finds Water and Organic Matter In Mercury

Quote
NASA has confirmed a surprising, counterintuitive discovery. The burning hell known Mercury—the closest planet to the Sun—has water. Frozen water. Three new research papers, based on data obtained by the Messenger spacecraft, show undeniable evidence.
It's not just a little bit of water, but a huge amount: enough to cover Washington D.C. in ice. But there is more: there's organic material too! NASA researchers believe that Mercury received this material in the same way as Earth did, millions of years ago. And that material, they say, were the building blocks of life.
The results—obtained with three different instruments—were being presented in a press conference at NASA HQ in Washington D.C. These findings confirm previous hypothesis and observations, but they are still surprising. Mercury is the closest planet to the Sun and has no atmosphere. That means that it gets extremely hot and extremely cold: The planet's surface temperature ranges from 50 K (-369.67F/-223.15C) to 700 K (800.33F/426.85C).
But thanks to its angle in relation to our home star, there are areas that are always in shadow. That's where the ice sleeps, protected from the sun's radiation by this shadow and dark organic deposits that insulate the water from the sun.
Even more exciting: NASA scientists think that this "complex mix of organic materials" is similar to the material that eventually gave rise to life on Earth. And as in Earth's case, scientists speculate that this material was probably brought to Mercury by comets colliding with the planet's surface.
The yellow inside the craters indicates the presence of water ice:

NASA scientists obtained this data using three methods: neutron spectrometry, near-infrared reflectance, and thermal models obtained by Messenger. The results are unequivocal; according to the project director "there's no other compound" it could be. Every piece of data coincides.

Jes ti sećaš da li su nas učili da Merkur ne rotira? A zapravo rotira jako sporo, dan (jedna rotacija) mu je duži od godine (jedna revolucija). A sunce u zenitu, gledano sa Merkura, zastane i vrati se unazad pa onda nastavi dalje...

Hello Jupiter! NASA spacecraft arrives at giant planet

Quote
PASADENA, Calif. (AP) — Braving intense radiation, a NASA spacecraft reached Jupiter on Monday after a five-year voyage to begin exploring the king of the planets.
Ground controllers at the NASA Jet Propulsion Laboratory and Lockheed Martin erupted in applause when the solar-powered Juno spacecraft beamed home news that it was circling Jupiter's poles.
The arrival at Jupiter was dramatic. As Juno approached its target, it fired its rocket engine to slow itself down and gently slipped into orbit. Because of the communication time lag between Jupiter and Earth, Juno was on autopilot when it executed the daring move.
"Juno, welcome to Jupiter," said mission control commentator Jennifer Delavan of Lockheed Martin, which built Juno.
The spacecraft's camera and other instruments were switched off for arrival, so there won't be any pictures at the moment it reaches its destination. Hours before the encounter, NASA released a series of images taken last week during the approach, showing Jupiter glowing yellow in the distance, circled by its four inner moons.
Scientists have promised close-up views of the planet when Juno skims the cloud tops during the 20-month, $1.1 billion mission.
The fifth rock from the sun and the heftiest planet in the solar system, Jupiter is what's known as a gas giant — a ball of hydrogen and helium — unlike rocky Earth and Mars.
With its billowy clouds and colorful stripes, Jupiter is an extreme world that likely formed first, shortly after the sun. Unlocking its history may hold clues to understanding how Earth and the rest of the solar system developed.
Named after Jupiter's cloud-piercing wife in Roman mythology, Juno is only the second mission designed to spend time at Jupiter.
Galileo, launched in 1989, circled Jupiter for nearly a decade, beaming back splendid views of the planet and its numerous moons. It uncovered signs of an ocean beneath the icy surface of the moon Europa, considered a top target in the search for life outside Earth.
Juno's mission: To peer through Jupiter's cloud-socked atmosphere and map the interior from a unique vantage point above the poles. Among the lingering questions: How much water exists? Is there a solid core? Why are Jupiter's southern and northern lights the brightest in the solar system?
"What Juno's about is looking beneath that surface," Juno chief scientist Scott Bolton said before the arrival. "We've got to go down and look at what's inside, see how it's built, how deep these features go, learn about its real secrets."
There's also the mystery of its Great Red Spot. Recent observations by the Hubble Space Telescope revealed the centuries-old monster storm in Jupiter's atmosphere is shrinking.
The trek to Jupiter, spanning nearly five years and 1.8 billion miles (2.8 billion kilometers), took Juno on a tour of the inner solar system followed by a swing past Earth that catapulted it beyond the asteroid belt between Mars and Jupiter.
Along the way, Juno became the first spacecraft to cruise that far out powered by the sun, beating Europe's comet-chasing Rosetta spacecraft. A trio of massive solar wings sticks out from Juno like blades from a windmill, generating 500 watts of power to run its nine instruments.
In the coming days, Juno will turn its instruments back on, but the real work won't begin until late August when the spacecraft swings in closer. Plans called for Juno to swoop within 3,000 miles (5,000 kilometers) of Jupiter's clouds — closer than previous missions — to map the planet's gravity and magnetic fields in order to learn about the interior makeup.
Juno is an armored spacecraft — its computer and electronics are locked in a titanium vault to shield them from harmful radiation. Even so, Juno is expected to get blasted with radiation equal to more than 100 million dental X-rays during the mission.
Like Galileo before it, Juno meets its demise in 2018 when it deliberately dives into Jupiter's atmosphere and disintegrates — a necessary sacrifice to prevent any chance of accidentally crashing into the planet's potentially habitable moons.

Men' nikad neće bit jasno nešto u vezi tih spejs travela....
Ako je gore tamo ništa izmedju nebeskih tela, onda ne bi trebalo da ima otpora sproću kretanja nečega.
Kako to da kad se neki endžin odvoji od Zemljine gravitacije i ne udari recimo ubrzanje od 1 metra po sekundi, to ubrzanje ne rase exponencijalno?
Sledeće sekunde putuje 2m/s, pa 3m/s, i sve tako u nedogled?
Šta ga to sprečava?

Pošto o tome postoje samo torije, uvek ću biti za to da je SajFaj mlooogo pametniji od svih "naučnika" .
Ko nam garantuje da NASA nikad nije ništa lansirala u spejs, nego samo sto tako, pusti nam neke CGI maštarije da opravdaju budžet?

Aaa, ti si dramatično pozaboravljo komplet osnovnoškolsku fiziku. Ubrzanje se dešava ako na telo deluje sila. Ako ne deluje ne dešava se, to nema veze sa vakuumom. Njutn pt. 2: The return of Njutn:


https://en.m.wikipedia.org/wiki/Newton%27s_Second_Law

Ahaaaa,,,,znači neko je odredio te zakone fizike da nemaju baš smisla sa našim maštarijama i željama, nego su pod uticajem neke više sile,inteligencije, itd.....lepo,lepo,,,bravo za njutna...otkud mu bre vakuum da to ispita sve,,,,svaka mu čast!

Taj Njutn, porobljivač slobodnih, rušitelj najtananijih ljudskih sanja  Kako li je pravio vakuum u laboratoriji, sigurno stara fora sveće i flaše...

Aha...na planeti zemlji vakuum u flaši i dalje ima gravitaciju, što nije isto van solarnog sistema.
Ali nema veze, ko sam ja da ispitujem Njutna, jelte...

Gravitacija i vakuum su sasvim različite stvari. Ispaljen metak na Zemlji, u atmosferi, ne pada na tlo jer ga vazduh uspori nego jer sila kojom je izbačen više ne deluje  a Zemljino gravitaciono polje je snažno na toj razdaljini. U "svemiru" bi mogao da nastavi da leti ako je dovoljno udaljen od gravitacionih centara (planeta i drugih nebeskih tela) ali ako na njega ne deluje neka sila - gravitaciona ili kakva druga  - neće ubrzavati.

Otkud znaš?
Si opalio metak u svemir?

Eh, tom logikom svaki put kad legnem da spavam treba da se pitam da li ću se probuditi kao žensko...



...ili leptir.

najn...not the same...
nema veze jedno s' drugim...

Pokušavam da kažem da je "sumnjaj u sve" zdrava logika dok ti ne parališe intelekt jer prestaješ da prihvataš ijednu potvrdu i sumnjaš u bukvalno sve. Onda postaješ Homer Simpson u ovom klipu:


https://youtu.be/l-W8Ox3YsAE

Eh, pa zar Ugli sumnja u sve? [emoji38] Drugi bi ga baš opisali kao nekog ko nepokolebljivo veruje u nešto.

Ama, naprotiv,ljudi, slažem se ja i sa svom fizikom, hemijom, ma šta hoćete dokle god je u domenu nauke i istine, sve mi pije vodu, ebre, pa ne bi bilo ništa od svega na svetu da nije tako.
Sve dok sajentisti ne krenu da teoretišu i fantaziraju mimo svojih okvira i to krenu da mi uvaljuju za nauku.
Ili kad krene nebitna polemika oko nevažnih stvari.
Tipa, ima tamo negde planeta na koju bi mogli da živimo, ali nikad nećemo stići tamo.U zabole me i da ima 100 000 takvih planeta.

Osim ako neko ne dokaže da vakuum u boci na planeti Zemlji nije isto što i vakuum u svemiru.

Da li je planeta stara 6 bijardi godina ili 6000...isto mu dodje, mi ni dan danas ne znamo tačan način izrade piramida od pre 3000 godina, a tripujemo se da znamo kako su se šetali pećinski ljudi i dinosauri...cvrc..I imamo neke fotke iz NASE koju sliko neki satelit....lakše da su pitali holivud da im sastavi....i jeftinije....

Naravno da nije isto šest milijardi i šest hiljada. Šest hiljada se ne uklapa u sve drugo što znamo o svetu.

Ako već sitničarimo, onda ću da kažem da 6 milijardi milimetara jeste 6 hiljada kilometara. [emoji38]
