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.'"

'Could' isn't the same as 'did'

I can speculate just as well as the next slashdotter. Mars could have done all sorts of things.

Confirmation of "could" does not equal speculation of "did". This is a pretty big deal.

From such maybes come later conclusions likely a good bit more concrete. Exploration and the resulting science is a process; it's not very smart to take a point in midstream and bitch about it. Don't hold your breath, go about your life, and eventually you'll catch notice of something that wows you, or enables your technology, etc.
