They're like little aliens, if only they had corrosive blood.

Maybe there are some of them on Mars.

Could be. The mars vehicles are throughly sterilized, but if some of these dudes were there and survived, it's likely they made it all the way to Mars. I wonder if the environment would be enough to get them out of hibernation, or if they'd die in their sleep.

You missed my point. People have always said that if life exists on Mars, not hitchhikers, but indigenous, it would have to be able to survive at very low temperatures with little oxygen. Life on Mars would have to be tough little creatures like your Tardigrades.

Ah, true that too. Exobiologists look at all these weird critters in order to suppose what kind of life could be in other planets. I really hope life there is life somewhere else on our solar system, even if it's microscopic. If all of it is sterile except Earth, life would be much more rare (and precious) that we currently estimate.

There are plenty of bacteria which are also extremophiles. I guess it's impressive that a multi-cellular creature is one too. Is it a little easier when you can have a protective shell that surrounds you, or more difficult because you've got more to protect?

But these dudes are polyextremophiles, that's even more awesome. As with machinery, simplicity = durability, and complexity = functionality. Tardigrades seem to have reached a good compromise between simplicity and complexity.
