This would be cool, but I have seen it in a few scifi stories.

How cool is that?

If it turns out to be true... wow.

It's interesting that if we do not find life on Mars that means nothing about how common life may be, however if we do find life on Mars that means that live is probably very common on other planets.

I would be surprised not to find life on Mars based on 2 facts:
1. Water use to exist on Mars in liquid form.
2. Life started on Earth very soon after it's formation.


If I knew then what I know now then I would know more now than I know.

Whilst I too entertained high hopes, I suspected that it might be something like this. It all came too fast and easy.

And the thought occured, the rovers are solar powered. Would they risk one in a dark cave just on batteries that might go flat, thereby jepordizing the remainder of the mission?

In short, while it's nice to know my bullshit dector was functioning again after a serious breakdown a short while ago, this does not mean there's no microbal life on Mars. I just don't think it'll be found on this mission.

Technically, there is no really, "remainder of the mission", as the rovers were planned to die out a long time ago, but haven't.

Why continue? Because we must. Because we have the call. Because it is nobler to fight for rationality without winning than to give up in the face of continued defeats. Because whatever true progress humanity makes is through the rationality of the occasional individual and because any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.

That is true, but, if I were running the show (Whatever Powers that Might Be forbid), I'd want to milk the last, sour drop out of it. I've little doubt that those in charge think the same. It's well into the profit margin now, and they want to keep it there as long as possible, yes?

Like the BA, I too am wondering if NASA will issue a statement.

Life on Mars, what does it mean? It says something about how rare life is in the universe. But, if they do find microbes on Mars and they find they have a lot in common - say, their genetic code is DNA, for example - with Earth Microbes, what does that say? Because Mars and Earth have exchanged meteors quite freqently over the ages, it may be that life was seeded here or there. So, it would actually ad ambiguity to our understanding of the history of life. And it would say nothing at all about how common life is in the rest of the galaxy/universe. However, if the life on Mars is completely different from Earth microbes - using a different set of amino acides and some other genetic material than RNA/DNA, now that would be something.

Mars could be where earth was millions of years ago. Earth was not always habitable either.

Um habitable by humans? Because last I checked bacteria can live in ridiculous extremes, not to mention 3 billion years of living...

Indeed. The more I read of extremophile life forms, the more convinced I become that if life can form under given conditions, it surely will.

And not just single-celled life. There are giant tube worms thriving around deep-sea, hydorthermal vents that are boiling on one end and fridgid on the other.

Amazing, and I suspect that we don't yet know the least of it. I don't think that we even know for sure the limits for the genesis of life, even here on earth.

Clearly we do not know the limits on earth, considering we find new unthought of creatures all the time, then we determine the best way to kill them.

Not only that, the kind of gasses solved in the water...

The proximity of extreme warmth and cold makes for an abundance of heat transfer, increasing entropy, which is one prime sources of energy for live.
