Did We Just Put Tardigrades on the Moon? Probably.

As far as tiny, cute, yet utterly bizarre animals go, tardigrades are almost certainly the best known. Also known as water bears, these creatures are only about a millimeter (1/25th of an inch) long, and they are known to survive in extreme conditions, even outer space. Now, it appears thousands of these tiny creatures may now be living on the Moon.

When the Beresheet spacecraft, designed and managed by Israeli space company SpaceIL, crashed into the Moon on April 11, the collision may have spread live tardigrades on the lunar surface.
