Curious Mars

Mars: March 2015

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.

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.
