§18322 Space Launch System as Follow-on Launch Vehicle to the Space Shuttle

Summary

NASA must build a new Space Launch System after the Space Shuttle that can reach cis-lunar space and areas beyond low-Earth orbit so the United States can join global efforts there. As soon as possible after October 11, 2010, the NASA Administrator must start developing the system. To keep costs down and keep needed parts available, the Administrator should extend or change existing vehicle contracts and ground-test contracts for solid rocket motors when practical. The rocket’s core without an upper stage must lift 70 to 100 tons to low-Earth orbit. With an upper Earth departure stage, it must lift 130 tons or more. It must carry the multipurpose crew vehicle and act as a backup for ISS cargo or crew if needed. The vehicle must be designed from the start to reach 130+ tons to LEO and allow growth to carry heavier loads. Development and testing of core and upper stage should happen in parallel when funded, with priority on the core and a goal of core operation by December 31, 2016. NASA must keep and develop skills in solid and liquid engines, large fuel tanks, rocket propulsion, and ground testing. The design should allow new technologies, sub-element competition, and commercial operations.
