- The animals that survived open space: Tardigrades, nicknamed water bears, are tiny animals about 0.5 mm (0.02 in) long. In 2007, scientists sent dried-out tardigrades into orbit on a space mission. For ten days, they sat in the raw vacuum of space. Back on Earth, water woke them up: the first animals known to survive the vacuum of space.
