Constellation Program Lapel Pin
Project Constellation is a NASA program to create a new generation of spacecraft for human spaceflight, consisting primarily of the Ares I and Ares V launch vehicles, the Orion crew capsule, the Earth Departure Stage and the Lunar Surface Access Module. These spacecraft will be capable of performing a variety of missions, from Space Station resupply to lunar landings.
Like that of the Apollo Program, Project Constellation will involve the Orion CSM flying near-Earth orbit missions, with the emphasis on servicing the ISS, and lunar orbit and landing flights. Currently (as of 2007), there are no immediate plans on the type of mission profile that would be flown to Mars, a mission which will not take place until after 2030.
