Ancient Mars Could Have Supported Life
sighted writes "NASA is announcing that analysis of a rock sample collected by the Curiosity rover shows ancient Mars could have supported living microbes. Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater last month. The announcement quotes Michael Meyer, lead scientist for NASA's Mars Exploration Program: 'A fundamental question for this mission is whether Mars could have supported a habitable environment. From what we know now, the answer is yes.'"
