A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA's Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments.

The detection of biologically important, organic molecules on Mars is an important goal that may soon be reached.

Mars Lost an Ocean's Worth of Water

A primitive ocean on Mars once held more water than Earth's Arctic Ocean, according to NASA scientists who measured signatures of water in the planet's atmosphere using the most powerful telescopes on Earth including the W. M. Keck Observatory on Hawaii.

We report new laboratory studies of the radiation-induced destruction of glycine-containing ices for a range of temperatures and compositions that allow extrapolation to Martian conditions.

A research team led by LSU Geology and Geophysics Assistant Professor Suniti Karunatillake reveals a spatial association between the presence of sulfur and hydrogen found in martian soil.

Old Dominion University faculty member Nora Noffke has made a name for herself as a geobiologist during the past decade by producing sedimentary evidence that prokaryote biofilms existed on Earth billions of years ago.

Tales from a Martian Rock

A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.

NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill.

In 2012 the Mars Science Laboratory landed in the fascinating Gale crater. The Gale crater is of such great interest because of the 5.5 km high mountain of layered materials in the middle.

How habitable was Mars in the past? Since the Curiosity rover touched down on Mars in August 2012, it has helped answer a few of these questions in the area surrounding its equatorial landing site of Gale Crater.
