NASAs current plan for returning to the Moon is Project Constellation 
which consists of designing two rockets the Ares_I and Ares_V, a manned 
capsule Orion, an Earth Departure Stage (EDS) [rocket], Lunar Surface 
Access Module (LSAM) and plans for a Moon Base.

The plan calls for the Ares_I launch vehicle to lift the astronauts in 
the Orion capsule into Earth orbit and for the larger Ares_V to lift 
everything else.

Two different design of rockets for the same mission appears expensive. 
  Since design costs are much larger than the small scale manufacturing 
costs I wonder if just the Ares_V needs designing?  Even if two 
different rockets are needed could the Ares_I be replaced by SpaceX's 
Falcon 9 Heavy rocket?

Alternately could NASA come up with its own rocket to launch the lot?
