Summary

DescriptionLEO Propellant Depot.jpg	In parallel with a GEO depot a cryogenic depot should be started in LEO. This depot could be used to top-off upper stages with propellant in orbit reducing the launch performance penalty for caring the propellant to space. This capability would have two significant advantages over not using a depot. First it would enable getting more with existing launch vehicles and second it reduce the size of future launch vehicles needed to perform missions with a single launch vehicle). Once this depot capability is operational larger missions can be performed, like going to the Moon, using existing launch vehicles reasonably soon.
