Life on Mars: More Hope From Life Here

I'm not obsessed with Mars story. Really, I'm not. But the stories coming fast and furious the past few weeks need to be read:

A new type of organism discovered in an Arctic tunnel came to life in the lab after being frozen for 32,000 years.

The deep-freeze bacteria could point to new methods of cryogenics, and they are the sort of biology scientists say might exist on Mars and other planets and moons.

"The existence of microorganisms in these harsh environments suggests -- but does not promise -- that we might one day discover similar life forms in the glaciers or permafrost of Mars or in the ice crust and oceans of Jupiter’s moon Europa," said Richard Hoover, an astrobiologist at NASA's Marshall Space Flight Center.

Even if life is not there now, it still pushes along the hope of human colonization one day. And, perhaps, that day will be sooner than we think.
