  •  There is kind of a lack of actual land (0+ / 0-)

    on Europa. I guess any realistic assesment of Mars would include Domes, so I guess the could float on Europa.

    But at least Mars has actual sunlight. Europa is far enough out the sun is pretty dim. Kind of a depressing habitat for humanity, floating under freezing water, no natural light.

    I think we're not sure how the human physiology will adjust to less gravity. Mars is less, Europa less still.

    And Mars, theoretically could be terraformed as colonists live under protection. Meaning in 10,000 years it may be more hospitable.

    I am in a agreement if there is vulcanic heat under the ice crust on Europa, it may hold life.
