Have we found a form of life that could make it on Mars?

Mars is cold. Minus ten degrees Celsius is a warm day, and all the water (which there is a lot of) is frozen into the soil as ice.

But, as they say in Jurassic Park, life finds a way (that isn't meant to imply the existence of Martian dinosaurs, as mind blowingly cool as that would be):
An microbe just discovered in the Arctic might be pointing towards such a way: It survives, and even thrives and reproduces, at a Mars-like minus fifteen degrees Celsius.
It's secret is that it has learned to live inside ice. Ice often contains tiny veins and pockets of water that stay liquid well below freezing, because they have a tiny amount of some kind of natural antifreeze (like common salt) in them. It's in these tiny oasis-in-the-ice that the newly discovered microbe makes it's home.

Here's the original press release.

Could something similar find a way to survive in the ice on Mars?

Well, we'll have to keep exploring to find out......
