Can germs and bacterias survive in vacuum space (e.g. outer space)?

Question

Can Microorganisms survive in vacuum environment? Is there a standard way to quantify vacuum space? What happen if an astraunaut expose some viruses, bacterias etc in outerspace?

Answer 1

Some bacteria can form spores that render them inactive, but would still be able to withstand the vacuum of space. Although the scientists do try to keep labs as sterile as possible, there is a chance that Mars has already been contaminated by Terran bacteria by the rovers and other things we've sent there. So, yes, there could be life on Mars!! Here's a pretty cool website on bacteria and experiments in space.

Answer 2

Can Bacteria Survive In Space

Answer 3

Feel some bacterias would not be able to survive in a vacuum, but a virus could survive. There is a new study where people with certain cancers when put under deep compression for a short time will kill the cancers. Looking forward for more new on this study.

Answer 4

Its widely known that germs or bacteria need oxygen and sunlight to survive and reproduce . However recent studies done in the deepest depths of the oceans have found animals as well as bacteria that survive not on oxygen but highly toxic environments that exist in super heated hydrothermal vents and absolutely no light from the sun . Instead of photosynthesis their lives are sustained by chemosynthesis

Answer 5

Yes, evidently so.
Evidence of living bacterial cells entering the Earth's upper atmosphere from space has come from a joint project involving Indian and UK scientists.

Answer 6

Yes, the Zerg swarm was engineered strong enough to withstand the rigors of warp space.

Answer 7

I don't remember which Apollo mission it was, but they brought back components from a lunar probe and there were still viruses on it that became active.
