NASA’s Mars rover Curiosity has found that surface soil on the Red Planet contains about 2 percent water by weight. That means astronaut could extract roughly 2 pints (1 liter) of water out of every cubic foot (0.03 cubic meters) of Martian dirt they dig up, said study lead author Laurie Leshin, of Rensselaer Polytechnic Institute in Troy, N.Y. read more

Now in another exciting development, NASA Goddard instrument makes first detection of organic matter on mars.

According to NASA, The team responsible for the Sample Analysis at Mars (SAM) instrument suite on NASA’s Curiosity rover has made the first definitive detection of organic molecules at Mars. Organic molecules are the building blocks of all known forms of terrestrial life, and consist of a wide variety of molecules made primarily of carbon, hydrogen, and oxygen atoms.

The surface of Mars is currently inhospitable to life as we know it, but there is evidence that the Red Planet once had a climate that could have supported life billions of years ago. For example, features resembling dry riverbeds and minerals that only form in the presence of liquid water have been discovered on the Martian surface.

While the team can’t conclude that there was life at Gale crater, the discovery shows that the ancient environment offered a supply of reduced organic molecules for use as building blocks for life and an energy source for life. Curiosity’s earlier analysis of this same mudstone revealed that the environment offered water and chemical elements essential for life and a different chemical energy source.

A fatty acid might be among organic molecules discovered on Mars by Nasa’s Curiosity rover.

However, it’s not possible at this stage to determine whether the compound has a biological or non-biological origin
