ABSTRACT

One of the main goals of astrobiology is the search for another type of life in our solar system. The planet Mars, Europa, one of the moons of Jupiter, and Enceladus one of the moons of Saturn, are the most likely targets for this search. With only one example of life on Earth it is not too surprising that we lack a precise definition of life or a clear strategy for how to search for it on other worlds.

[TCthaCrisis]

[ananiasacts]
