Title 42 › CHAPTER 159 — SPACE EXPLORATION, TECHNOLOGY, AND SCIENCE › SUBCHAPTER II — EXPANSION OF HUMAN SPACE FLIGHT BEYOND THE INTERNATIONAL SPACE STATION AND LOW-EARTH ORBIT › § 18322
NASA must build a Space Launch System to follow the Space Shuttle. It must reach cis‑lunar space and areas beyond low‑Earth orbit so the United States can join international efforts there. The NASA Administrator must start work as soon as practical after October 11, 2010. To keep costs down and preserve needed work, the Administrator should extend or change current contracts when practical, including contracts for ground testing of solid rocket motors. The rocket must at least do four things: the core parts (without an upper stage) must lift 70 to 100 tons to low‑Earth orbit; with an Earth‑departure upper stage it must lift 130 tons or more; it must be able to carry the multipurpose crew vehicle; and it must be able to back up cargo or crew trips to the ISS if commercial or partner vehicles cannot. The SLS must be designed from the start to reach 130+ tons to low‑Earth orbit and allow growth to carry heavier payloads, new technologies, competition for parts, and commercial use. Work on core and upper stages should go forward together as funds allow, with priority on the core so it is ready by December 31, 2016. NASA must keep and build skills in engines, large fuel tanks, rocket propulsion, and ground testing.
