Hmmmm... this doesn't look like it will ever lead to either conclusion on it's own. Kind of a piece of circumstantial evidence I suppose. It seems like something that really is going to need some complimentary evidence either way, in order for it to gain any real value of it's own.

Although I suppose it's possible some new technology or knowledge could change all that. We really need to get some people to that planet to do some exploration.

Anyone got an opinion among this council of learned people of Zubrin's "Mars Direct" concept? I imagine sts60, Jay and a few others would have a good insight into this.

(second thoughts, I should use my head and use the search function)
