Three Solar System Locations for Searches for Microbial Life

Post by Christopher K. » June 2nd, 2012, 1:15 pm

Though I'm far from an expert, over the years I've encountered multiple mentions of three locations in our Solar System which seem to have a higher-than-average chance of harboring microbial life.

1) Under the soil of Mars: Martian microbial life is still a distinct possibility. Fred just started a thread concerning the reevaluation of the Viking findings.
2) Under the ice of Europa: Evidence strongly suggests a liquid environment at a certain depth, and radiation from Jupiter could release oxygen into that environment.
3) In the atmosphere of Titan: Hydrocarbons form in Titan's upper atmosphere probably due to the breakdown of methane by solar UV radiation. It's just possible microbes could be frolicking aloft among the molecules.

David Darling bumps up the list of possible locations to four, adding Callisto.

There has been speculation for decades concerning the possibility (and difficulty) of altering Mars' atmosphere to suit human beings. The MAVEN mission is slated to leave Earth on 18 November; its goal is to determine if the Sun was primarily responsible for stripping Mars of most of its original atmosphere.
