NASA: Mars could have supported life

The Curiosity rover has found the best evidence yet that Mars was once a habitable planet.

The rover made the discovery by collecting rock samples using its on-board drilling tool and analyzing them using its science instruments. What it found was that the rock contained clay minerals, a clear indication of the presence of neutral water. Ultimately the discovery suggests that at some point in the past there were at least some areas of Mars capable of supporting life as we know it.

"We have found a habitable environment that is so benign and supportive of life that probably if this water was around and you had been there, you would have been able to drink it," said project scientist John Grotzinger.

"The US space agency (Nasa) has reported that its Curiosity rover has made another significant discovery on Mars."

It is one thing to have the chemical elements, compounds, water and other conditions necessary for life and quite another to find life itself. The DNA molecule is one of the most (if not the most) complex known and along with RNA and protein is necessary for life as we understand. It is quite a step from have carbon, oxygen, etcetera to having a DNA molecule or something remotely complex as a living cell. I suppose it is possible to have a truly alien biology of some sort, but if that is the case would we overlook it in favor of how we understand life to exist?

Sundew - Who's to say any life Curiosity finds will be completely alien?

Yes. Earth and Mars have apparently been trading rocks, blasted off one by asteroid impacts, and eventually falling onto the other, just about forever. It seems that simple life, lodged inside the rocks, might survive the trip. Mars, being smaller than Earth, may have cooled sufficiently for life to take hold there first, and then colonize Earth. We could all, in a sense, be Martians, at least by ancestry.

Here is the video of the press conference where these findings were announced. At just over an hour it is quite a long video, but well worth watching. [hr] Analysis of the first sample of rock powder ever collected on Mars is discussed in this NASA TV briefing from the agency's headquarters in Washington, D.C. on Mar. 12.

Curiosity's analyzed rock sample proves ancient Mars could have supported living microbes.
