Swedish Experiments Expose Animals to Space Environment

This interesting article in The Daily Galaxy tells the story of an experiment to test the ability of a certain type of animal, the Tardigrade, to survive exposed to the space environment. Tardigrades are a small sized (<2mm)> space environment. Swedish scientists found that 2% of the specimens could be revived after 10 days of exposure to the full extremes of the Low Earth Orbit (LEO) space environment.

This is an interesting experiment because it really challenges the common perception that life on Earth can only ever stay confined to that thin layer of soil and atmosphere that we call home.

Could rugged species like the Tardigrade could stay alive in the cores of asteroids for far longer periods enabling them to populate other planets and spread life?
