Recent studies have indicated that some tardigrades in Antarctica can survive in the hydrated state in temperatures as low as -80 C. Tardigrades have the ability to go into cryptobiosis, a hibernation-like state in order to survive these fluctuating conditions in their environment (Kinchin, 1994, Somme, 1995b, & Somme, 1996). These organisms are impossibly cute, like tiny blimps bumbling around harmlessly on their stubby little legs, but they also enjoy a legendary reputation as the toughest and most indestructible creatures on Earth.

Tardigrades, or water bears, are pudgy, microscopic animals that look like a cross between a caterpillar and a naked mole rat. It turns out tardigrades have developed a range of handy tools to help them avoid death time and time again - including a protein that acts as an in-built radiation shield for DNA. , a tardigrade can survive for decades or more. The ship had no humans on it (just experiments) but humans watched it from earth. Tardigrades can live in space (sort of) In 2007, dehydrated tardigrades were taken up into orbit and exposed to the vacuum and radiation of space for 10 days.
