NASA Human Space Exploration: Significant Investments in Future Capabilities Require Strengthened Management Oversight, Report to Congressional Committees [open pdf - 4MB]
From the Highlights: "NASA is pursuing an aggressive goal to return American astronauts to the surface of the Moon by the end of 2024. The success of NASA's plans hinges, in part, on two upcoming test flights. An uncrewed test flight and subsequent crewed test flight are intended to demonstrate the capability of a new launch vehicle, crew capsule, and ground systems. The House Committee on Appropriations included a provision in its 2017 report for GAO [Government Accountability Office] to continue to review NASA's human space exploration programs. This is the latest in a series of GAO reports addressing this topic. This report assesses (1) the progress the programs are making towards the first test flight, known as Artemis I, with respect to schedule and cost, and (2) the extent to which NASA's human space exploration programs are positioned to support the planned Artemis flight schedule beyond Artemis I."
