The Johnson Space Center in Houston will be the base for mission control, and for overall management of Project Constellation. In this photo from 1970, engineers discover that the spacecraft in the Apollo 13 mission--an early and aborted lunar landing effort--is leaking oxygen.
The Marshall Space Flight Center in Huntsville, Ala., will design the Crew Launch Vehicle's first stage and is responsible for launch vehicle testing.
The Glenn Research Center in Cleveland will be responsible for the Crew Exploration Vehicle service module. The agency will develop the propulsion system, the solar arrays for the power system, and the heat rejection radiators for keeping the vehicle cool.
