NASA Scientists Find Evidence of Water In Martian Meteorite
An anonymous reader writes "Scientists at NASA and JPL have found evidence of past water movement throughout a Martian meteorite, reviving debate over life on Mars. 'In this new study, Gibson and his colleagues focused on structures deep within a 30-pound (13.7-kilogram) Martian meteorite known as Yamato 000593 (Y000593). The team reports that newly discovered different structures and compositional features within the larger Yamato meteorite suggest biological processes might have been at work on Mars hundreds of millions of years ago. ... Analyses found that the rock was formed about 1.3 billion years ago from a lava flow on Mars. Around 12 million years ago, an impact occurred on Mars which ejected the meteorite from the surface of Mars. The meteorite traveled through space until it fell in Antarctica about 50,000 years ago.'"
We are all martians
They seem obsessed with saving Dan Quayle's personal image...
give it a rest wright brothers, you have been trying forever and you just wont ever fly....
have you seen my sig? there are many others like it but none that are the same
Frankly ,there's nothing on Mars alive today . Even if there has been 100 millions years ago , we're still alone. It don't change a thing in our lives.
Scientific interrest is the only interest. As a human being we got troubles here that need a lot more attention and focusing to solve.
Check Ukraine being invaded by the Soviets. Check wars all around. Do we really want extraterrestrials to see us under that kind of light ?
Warmongering , selfish, murderous ? I'd rather we take the cash from all those studies and solve the real problems we all face.
First on the list is our own extinction.
nonsense, no amount of U.S. money will solve problem of why Russia (not soviets, no such thing any more) is going to invade Ukraine.
the minuscule amount of money spent on space exploration hurts nothing.
Agreed, but if they gave up before they started just because it never happened before, where would we be? sure you could argue someone else would pick up where they left off

too late.
Harrison's Postulate - "For every action there is an equal and opposite criticism"
It's not like we don't have what are essentially remote science laboratories that we've sent there which should theoretically be able to find this sort of stuff in the samples they collect.
File under 'M' for 'Manic ranting'
The probes/rovers/landers have/had electron microscopes?

The title isn't misleading at all, you're simply lacking reading comprehension. My 6 year old has better reading comprehension than you do. Evidence by its very nature is generally something that is produced or an after effect of some other process. A scratch on a car door is evidence that something harder than the surface scraped against it. You don't need the key that did it to say that the scratch is evidence of it....
How many times do we get to "discover" that bears actually do shit in the woods?
(This is years after we've seen clear pictures of Martian flood plains, with obvious river channels. This is years after we've detected signals for hydrogen under the Martian surface. This is years after models of solar system history basically make the conclusion inescapable that early on, Mars would have had to have liquid water. And I could go on.)
they traveled the surface of mars... but thats not to say that there isnt water somewhere underneath the surface.
Pressure to influence money sources.
" Check wars all around. Do we really want extraterrestrials to see us under that kind of light ?"
We would want a war;ike race like the martians to see us like that, then they might think twice about invading us.
Then they might go to Saturns rings to get their water rather than here.
Jupiters moon Europa is more likely than the planet itself.
I wouldn't bother checking Pluto because even if there was life there, it would be pissed at us for demoting them to not living on a planet.
"check under the Sun!"
everything under the sun is in tune but the sun is eclipsed by the moon.
this is incredibly short-sighted. exploration of Mars and our Solar System can and often does lead to advancements with practical scientific applications. better and more efficient energy sources. better ways to grow food. even the potential for colonizing planets like Mars in the future. these benefit humanity on an enormous scale. the only falsehood here is claiming that humans can't tackle both immediate geopolitical conflicts and longer-reaching scientific advancement. we should be doing both.
Don't worry, they're not bitter. It's just the crazy space nutter troll. I've been a bit worried about the poor space nutter troll lately, what with missing quite a few space articles, while posting in articles that have nothing to do with space. It's nice to see the manic screeds back where they belong.
Well, go look back at history and look at all the other competing aircraft designs that failed.
The Wright brothers design was one of the ones that failed.
