One fun thing about Deimos is that apparently it takes the same amount of delta-V to travel to the surface of Deimos as it does to the surface of the Moon. Beca

One fun thing about Deimos is that apparently it takes the same amount of delta-V to travel to the surface of Deimos as it does to the surface of the Moon. Because of the Moon's much larger gravity. There have been people playing with the idea of using it as a refuelling station, because it's thought to contain a lot of water.
