First Animal to Survive in Space

Tardigrades or “Water Bears” are the only creatures that can survive the extreme conditions in the vacuum of outer space.

Waterbears can go without food or water for more than a decade. They can survive temperatures from zero to above the boiling point of water, pressure six times stronger than the deepest ocean trench, radiation hundreds of times higher than the fatal dose for a human, and the vacuum of space.
