This Curiosity Image Suggests Microbial Life Once Existed On Mars

It may not look like much — just an old rock with dust on it. But after careful examination of this and other images taken of the Martian surface, a geobiologist is now claiming that these distinctive surface features could have only come from one source: microbes. » 1/06/15 9:00am 1/06/15 9:00am

Drinkable Water Once Flowed on Mars

Not to be outdone by Curiosity, the Opportunity rover has made one of its most significant scientific discoveries to date. A recent analysis of clay minerals indicates that neutral water once existed on Mars — water that could have been suitable for life. » 6/10/13 1:27pm 6/10/13 1:27pm

Did NASA send the Curiosity Rover to the wrong place?

A new study suggests that Mars’s 3.5-mile high Mount Sharp formed as strong winds carried dust and sand into the crater in which it rests. If true, Gale Crater probably never contained a lake, which would totally suck, because that’s one of the main reasons why NASA sent Curiosity there in the first place. » 5/09/13 9:15am 5/09/13 9:15am

Curiosity Confirms That Mars Was Once Capable of Harboring Life

The Curiosity Rover has just accomplished exactly what it was set out to do. According to NASA scientists, the probe's latest analysis of a Martian rock sample shows that ancient Mars was once capable of supporting living microbes. It’s not confirmation of life; rather, it's evidence for the Red Planet's historical » 3/12/13 1:27pm 3/12/13 1:27pm

Mars once had water warm enough to sustain life

We know that Mars once had lots of water, considered a prerequisite for habitability. What hasn't been known, however, is just how friendly — or unfriendly — this water might have been to life, as the temperature and chemical conditions of ancient Martian water has remained a complete mystery. But as a new analysis… » 11/19/12 8:00am 11/19/12 8:00am
