Answers may be locked inside Martian 'bedrock'

Me, I'm betting against Nick because the geologic morpholgy clues seem so obvious (and he thinks going to Phobos first is a good idea), but I appreciate his scientific skepticism and rigorous debate. While it's true that a cause in one setting may not be the same cause in another, choosing a cause that's never been demonstrated is not usually the good bet. It's the guys that buck the odds and are proven right that go down in history though. That is if unlike Levin, their data proves to be a significant part of the final case. I think there's still a significanr chance of life on Mars, but not in the samples Viking tested.
