Andrew Knoll's Opinions

Extraterrestrial Life Was there life on Mars? Mostly Disagree Our sense has been that while Mars is a lousy environment for supporting life today, long ago it might have more closely resembled Earth, but this result suggests quite strongly that even as long as four billion years ago, the surface of Mars would have been challenging for life. No matter how far back we peer into Mars' history, we may never see a point at which the planet really looked like Earth. Edit Pitches 29 May 2008    Source
