In a dried-out dormant state, tardigrades can survive the vacuum of space and pressures about six times those of the deepest ocean trench, and some species survive radiation doses hundreds to about 1,000 times what would kill a human.
Notes on verification
Verified through multiple space experiments and peer-reviewed studies in astrobiology journals
