La vita su Marte? Sembra la volta buona!

Nuove prove di vita su Marte? A leggere i comunicati della Nasa sembrerebbe proprio la volta buona!

Le trivellazioni di Curiosity sul suolo marziano hanno rilevato la presenza di azoto, carbonio, fosforo e zolfo: gli ingredienti di base della vita.

NASA Rover Finds Conditions Once Suited for Ancient Life on Mars

An analysis of a rock sample collected by NASA's Curiosity rover shows ancient Mars could have supported living microbes.
Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon -- some of the key chemical ingredients for life -- in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet last month.
"A fundamental question for this mission is whether Mars could have supported a habitable environment," said Michael Meyer, lead scientist for NASA's Mars Exploration Program at the agency's headquarters in Washington. "From what we know now, the answer is yes."
On Tuesday, NASA’s Jet Propulsion Laboratory announced that an analysis of a rock sample collected by the Curiosity rover shows ancient Mars could have supported living microbes. Some key chemical elements for life - sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon - were discovered in a powder sample Curiosity drilled out of a sedimentary rock near an ancient stream bed in the Red Planet’s Gale Crater.
