Dear, My question sounds completely crazy at first sight. Mars has no water on its planet and the moon Enceladus has too much. If there was less water on this moon and more water on Mars, then they would both be habitable, so two birds with one stone. But I was wondering if you had to make a tube 1cm in diameter from the ocean to Mars and since there is a gravitational difference whether the law of communicating vessels would work and whether or not how much negative pressure should a pump give to pump water from enceladus to get to mars? Thanks in advance, Thibault,
Answer
For starters, there is water on Mars, in the form of ice, in the polar caps, in some volcanic craters, and underground. Mars is much larger than Enceladus, and undoubtedly contains much more water. I also don’t understand why there would be ‘TOO much’ water on Enceladus.
Also consider that Mars orbits the sun with a period of about two years, and Enceladus, along with Saturn, orbits the sun with a period of about 26 years. The mutual distance between the two changes constantly, so there must be good stretch on your tube, and meanwhile your tube would come dangerously close to the sun.
