“A fundamental question for this mission is whether Mars could have supported a habitable environment,” says lead Mars Exploration Program scientist Michael Meyer, quoted in a NASA press release today. “From what we know now, the answer is yes.” He’s referring to the latest Curiosity findings announced at a press conference today, which NASA says “shows ancient Mars could have supported living microbes.” That evidence specifically comes from powder the Curiosity rover drilled out of a rock near an ancient stream bed in Mars’ Gale Crater, which contained sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon — “some of the key chemical ingredients for life,” as NASA puts it. Mars Science Laboratory scientist John Grotzinger further explains that “we have characterized a very ancient, but strangely new ‘gray Mars’ where conditions once were favorable for life,” adding, “Curiosity is on a mission of discovery and exploration, and as a team we feel there are many more exciting discoveries ahead of us in the months and years to come.” You can find the full announcement after the break.
