Comment Comment by crubier The delta-v from Earth Surface to Low Earth Orbit (beginning of space exploration) is 9km/s.The delta-v from Earth Surface to Moon is 15km/s.So basically once you learned to go to space, going to the Moon is "only" 60% harder, even thought the moon is 1000x further away. parent crubier 5 years ago
