mikefromlondon said:Force of gravity weakens inversely proportional to its distance, but never completely disappears, but for practical purposes we can say that the space lab has a very weak influence from the earth's gravity due to its distance away from earth, the earth may still exert some minute pull at it, and hence every so often most satellites and space stations need correction via small rockets, hence all satellites must carry some on board fuel for this correction, hence the amount fuel for correction is what determines a life of a satellite.
So, how much fuel is on the moon? we should go mine it!
