Mars Rover Finds Mineral Vein Deposited by Water

http://www.jpl.nasa.gov/news/news.cfm?r … l&rst=3220

"This tells a slam-dunk story that water flowed through underground fractures in the rock," said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for Opportunity. "This stuff is a fairly pure chemical deposit that formed in place right where we see it. That can't be said for other gypsum seen on Mars or for other water-related minerals Opportunity has found. It's not uncommon on Earth, but on Mars, it's the kind of thing that makes geologists jump out of their chairs."


ExoMars' launcher's 2nd stage is probably en route to Mars. Unsterilised... yikes

Re: Mars Rover Finds Mineral Vein Deposited by Water

Saying it is a slam dunk is a bit of hyperbole, IMHO.  There has been plenty of evidence for past liquid water on Mars already, and some evidence for it being locally present today, at least some of the time.  If people aren't going to be convinced by outflow channels, meandering channels, fans, gullies, hydrated minerals, salt crystals, concretions, water ripples, and aqueous minerals in martian meteorites, they aren't going to be convinced by this.
