A roughly 3.5-mile high Martian mound that some scientists suspect preserves evidence of a massive lake might actually have formed as a result of the Red Planet's famously dusty atmosphere.
In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the red planet more than a billion years ago.
What do manned missions to Mars and marijuana have in common? Well it seems that NASA’s only way to get to Mars is by getting high and now a former NASA scientist is looking to apply his life-support expertise to marijuana growing.
Mars may have lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate.
NASA's Mars Curiosity rover has identified evidence of water-bearing minerals in rocks near where it had previously found clay minerals inside a drilled rock.

Ridges in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed.
An international team of researchers studying data beamed back by NASA's Mars Reconnaissance Orbiter have observed seasonal changes on far-northern sand dunes on the Red Planet caused by warming of a winter blanket of frozen carbon dioxide.
NASA's Mars Reconnaissance Orbiter (MRO) has found evidence that McLaughlin Crater once contained a lake fed by flowing groundwater.
The European Space Agency's (ESA) Mars Express has captured a detailed image of the upper part of the Reull Vallis region of Mars.
An international team of researchers from Los Alamos National Laboratory and the French Space Agency say they have managed to track a trail of minerals that point to the prior presence of water at the Curiosity rover site on Mars.
