Bacteria in spaeships
What are we going to do about preventing Earth bacteria
from contaminating Mars biota when we set foot on Mars? You're assuming that there is an actual living Mars biota. This has not been proven. There are signs that Mars may have had life in the distant past, but we do not have any definitive evidence that proves life exists on Mars today. Isn't my assumption. It's NASA's. Please cite this NASA assumption that there is an actual living Mars biota. Note that spacecraft sterilization efforts do not demonstrate such an assumption, since we did the same thing for lunar probes and nobody thought there was an actual living biota there. Then why are they sterilizing landers? Do they also sterilize satellites? As for the moon, did they sterilize the suits used for moon walks? Did the moon lander or the moon walkers expell any air while on the moon? |
