These results suggest the Beresheet tardigrades probably didn’t survive their lunar landing, Traspas Muiña says.
The machine launched tardigrades at different speeds, ranging from about 550 to 1,000 meters per second, into bags of sand meant to mimic the lunar surface.
Smashing into sand faster than about 825 meters per second, or about one gigapascal of shock pressure, proved lethal for the tardigrades.
Likewise, space rocks flying around the solar system usually smash into planets and moons at thousands of meters per second — far too fast for tardigrades to survive.
The findings hint that even intrepid little animals like tardigrades would struggle to survive crash-landing on a new planet.
