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.'"

So why can't they find this stuff on mars?

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.
