fusillade762: Ambivalence: So what happened to it?

I think the theory is that Mars lost its magnetic field and solar radiation fried the place. Any scienticians feel free to correct me if I'm off base.

I'm not a scientician, but I do have an internet degree in doctorology.

With enough time, other things than water can create the photographs that we're presented.

Sure ... but what, if not liquid water? Not shutting you down, this is unsettled science. Which means it's exciting.

Wind weathering produces things that look like this:

But a lot of water produces the Seaview:

I'm sort of hoping there is no life on Mars, at least not currently. Then we won't have any ethical issues should we ever want to terraform the planet.

cman: Ambivalence: So what happened to it?

Probably someone on our planet had some sort of tame-travelling predestination paradox into the past and somehow killed all life on Mars by accident. When it comes to destroying life, we humans are #1

It was a sound of thunder...

justtray: There is almost certainly life on Mars.

There are giant sinkholes in the surface of the planet that are clearly visible. Around these zones, as the seasons change, the amount of Methane in the atmosphere increases signficantly. The only process we know that releases methane into the atmosphere like this is biological.

So the question really is, "Why aren't we searching for life on Mars?" We know where to look, and we aren't even trying.

So what you're saying is that there are cows in the sinkholes, is that right then?

soosh: Marcus Aurelius: Richard Saunders: Just because it's a fluid, does not mean it's water...

/or did I not get the memo?

Other solvents tend not to wear rock in the same fashion. Mars rock is composed from a lot of silicon and lesser basalts than Earth, but water erosion is distinct from streams of, say, liquid methane. Water is polar; it hydrates silica minerals, and has an astonishing vapor pressure to atomic weight ratio.

Meanwhile the chances of Mars getting cold enough to liquefy methane in volume and rain it from the sky in sufficient quantities to erode rock is between slim and none.

well sure. but what if it wasn't liquid methane but rather iced tea? didn't think of that, did ya?

That would explain the red color, no doubt. But given the convenience stores wars we have on this planet between Wawa and 7-11 and the Gook-n-Go, I think we can assume that Taco Bell won the war on that planet.

Sad, really.
