Some examples of D V's for particular missions are also shown in the D V vs Rocket Mass figure. It is very expensive in D V to go from the surface of the Earth to low Earth orbit (LEO); the Space Shuttle works very hard for that first 280 km of altitude! Once in LEO, missions to geosynchronous Earth orbit (GEO), where satellites appear to remain stationary over the same spot on the Earth, or to the lunar surface, require only modest D V's.
