Tardigrades were able to survive impact velocities of 825 meters per second, but survival rate fell to 0 at 901 meters per second, the researchers added. Thus, shortly after the onset of lethality, the tardigrades were also physically broken apart as impact speed increased,' the researchers penned. 'However, even in the event some of this material was lightly enough shocked to permit tardigrade survival, long-term exposure to solar and cosmic radiation would still have sterilized much of it.' 'These values are well within survival limits for tardigrades at Enceladus, but they are too great for survival at Europa,' the researchers wrote. In October 2020, researchers found that a variant of tardigrade can survive UV radiation thanks to a protective shield that turns the harmful radiation into blue light.
