NASA Constellation Projects Influence on Architecture Selection

July 30, 2009, NASA closed the influence of key drivers on architecture selection for exploration crew transport. NASA developed human spaceflight with ISS crew transport using the spacecraft Orion, aligning with new needs, goals, and objectives from the VSE ‘05/’08. Missions beyond LEO have no maximum commonality or cost-sharing. NASA continues with the Shuttle Orbital Space Plane for Crew and Cargo separation. The new exploration architecture aims for significant safety improvements over legacy systems like Ares V and Shuttle C, enhancing heavy lift capability with Ares V, crew launch with Ares I, and lunar surface access with Altair. The overall goals of the Constellation program are to reduce net costs of LEO access, enhance crew safety, and extend human operations beyond LEO. Current and future development includes deep space robotics, asteroids, near-Earth objects, Mars exploration, lunar orbit, surface missions, and servicing the ISS.
