HOW did the Lem took of from the moons surface.?

Question

The Saturn rocket has so much fire power to make it move 41,000 km/h for it to escape earth’s gravity.the lem should fly at 8,000 km to do the same.but looking at the size of its rocket booster it could not have break free from the moon gravity

Answer 1

The LEM only had to achieve orbital velocity to dock with the command/service module. orbital velocity is less than escape velocity (divide it by the sqare root of two). It's miniscule, anyway,compared to achieving orbital velocity of the earth.

Answer 2

Oh REALLY??? Someone tell NASA!
