As I understood these were actually bacteria that were observed to have survived being in space, as in on the external surface of satellites and shuttles, or extreme-like conditions. One problem related to detecting life on other planets is that a number of bacteria are suspected to be able to survive the whole trip to whichever planet or space object we send a probe to.

- Retric 8y agoThat’s true, but not on all surfaces. The back side of solar panels for example don’t receive direct sunlight. But, even a bolt will provide plenty of shade for bacteria. Plenty of nooks and crannies to go around. Space qualified lubricants can even provide a growth medium. Anyway, my original point was more in line with this. “Our results predict that most terrestrial bacteria would be inactivated within the first [day] on Mars if contaminated spacecraft surfaces receive direct sunlight.” And remember Mars gets far less sunlight than earth.
