Israeli lunar lander Beresheet crashed onto the surface of the Moon on April 11 — and it may have left more than a pile of wrec
kage. It was also carrying thousands of tardigrades, small micro-animals often referred to as “water bears.öWhy it matters: bec
ause, according to Wired, tardigrades are the “toughest animal in the known universeö — so resilient that they’ve been found li
ving on the exterior of the International Space Station. In other words, there may now be life on the Moon.Beresheet’s tardigra
des probably won’t be crawling around on the lunar surface, because scientists dehydrated them first — though they can be reviv
ed for years after the procedure.As for the harsh climate of the lunar surface, tardigrades can survive temperatures as low as
– 328 degrees Fahrenheit — and don’t even have to be dehydrated to do so. Earlier this year, China’s Chang’e-4 lunar probe foun
d that the lowest temperature it measured during the night was – 297 Fahrenheit.In other words: though it’s not clear how long
it might survive, humans may have now accidentally contaminated the Moon with life from Earth.
