They are talking earth shattering news to come out in a few weeks, all hush hush for now.
Some people are saying they found proof that life CAN'T be on Mars. News at 11 in a few weeks though!
As we have not yet fully bounded the conditions in which life can exist, and the known
examples get pretty extreme.
Given the short elapsed time I would say that it's more likely that they are gearing up
to announce the discovery that there was life on Mars (or less likely that there IS life on Mars).
However, I'll get excited if and when they actually make that announcement... And people
have checked and double checked it for errors.
It wouldn't be the first time that people have got over excited about this kind of things before.
Originally posted by sonhouseI predict they actually found proof of life there. What would be better is if they found a living organism there. Not that it makes much difference but it would finally put the question to bed.

should be common.
Complex life that might have a thigh bone is very rare and hard to form.
We went for billions of years with only bacteria before one single solitary organism
developed the trait that allowed it to become complex in an unbelievably unlikely
fluke accident. (it swallowed another that could be used as a power source)
Given that Mars had a much shorter window in which life could potentially exist before it
froze and lost it's atmosphere, I would say that the chances of Mars ever having anything more
exciting than mats of bacteria on it are pretty slim.
That said it would be awesome to be proven wrong on this ;-)
Originally posted by joe beyserMy guess: They sniffed out methane, a gas that is usually associated with life. Only problem is, it's difficult to tell life methane from volcanic methane which is maybe why they have backed off the 'earthshaking' announcement.
Maybe a few spent 30 30 shells laying on the ground.
If it was some kind of undeniable image of a life form, some kind of likens or mossy stuff they would have trounced on that kind of thing so it has to be something more subtle.
