Planetary Astrobiology
The best candidate within our own solar system for finding microbial life forms is planet Mars. There is much geological evidence that liquid water has been present on Mars throughout much of its history. Liquid water and environmental conditions on early Mars similar than on Earth enhance the possibility that life developed independently both on Earth and Mars. |

Results of the Galileo probe have been interpreted as indication that a salty subsurface water ocean or water/ice slush may be present on Jupiter's satellite Europa, which marks it as a second candidate for a possible habitat of alien life forms in our solar system. Saturn's huge satellite Titan provides a unique milieu to study, insitu, the products of fundamental physical and chemical interactions driving planetary organic chemistry and serves as a natural reference laboratory to study by default, the role of liquid water in astrobiology.
