The "Engine Testing for Exploration Act" requires the National Aeronautics and Space Administration (NASA) to maintain robust rocket propulsion system testing capabilities . This includes ensuring the continuity of internal expertise necessary to test and evaluate these systems, potentially through partnerships with the private sector. The bill specifically mandates that NASA's Stennis Space Center will continue to manage these critical testing programs, leveraging its unique infrastructure and expertise. Congress finds that such testing is essential for the operation of current and future deep space exploration rockets, including crewed missions to the Moon, as it reduces risk and improves safety . Maintaining this core competency allows NASA to be an informed purchaser of commercial rocket engines. Furthermore, the Administrator is directed to brief Congress within 180 days on NASA's plans for rocket propulsion system testing and evaluation for missions in low-Earth orbit, deep space, and for space launch vehicles certified for government astronauts.
