Plain Language Summary

# NASA Transition Authorization Act of 2025 - Summary **What This Bill Would Do** This bill would provide funding authorization for NASA's programs and activities through the end of fiscal year 2025. It focuses on continuing and expanding America's space exploration efforts, particularly through two major initiatives: the Artemis program (which aims to land astronauts on the Moon) and Mars exploration. The bill emphasizes public-private partnerships, meaning NASA would work with commercial companies to achieve these goals. A key provision requires NASA to maintain continuous human presence in low-Earth orbit even after the International Space Station (ISS) is retired, potentially by opening contracts with private companies to build and operate commercial space stations as replacements. **Who It Affects and Current Status** This bill would impact NASA employees and contractors, private space companies competing for contracts, and ultimately U.S. taxpayers who fund space exploration.

It also affects international partners who currently collaborate on the ISS. The bill is currently in committee review, meaning it has been introduced but hasn't yet been debated or voted on by the full Senate. The bill would require the development of a "de-orbit vehicle" to safely bring down the aging ISS when it's no longer needed. Sponsored by Senator Ted Cruz (R-TX), the bill represents Congress's effort to shape NASA's long-term direction and ensure smooth transitions between government-operated and commercial space infrastructure.

CRS Official Summary

NASA Transition Authorization Act of 2025This bill reauthorizes through FY2025 the programs and activities of the National Aeronautics and Space Administration (NASA). The bill also revises certain existing NASA programs and establishes new programs related to space exploration, research, and technology.For example, the bill directs NASA to continue its efforts to support crewed lunar landings and Mars explorations, including through partnerships with the private sector (i.e., the Moon to Mars and Artemis programs).The bill also requires NASA to maintain the capability for a continuous human presence in low-Earth orbit until and beyond the retirement of the International Space Station (ISS). NASA may solicit proposals for the development of a commercial space station in low-Earth orbit. When such a station is ready, NASA must initiate an orderly transition of operations from the ISS to the commercial station. NASA must also develop a de-orbit vehicle for the eventual retirement of the ISS. (Low-Earth orbit encompasses orbits at an altitude of 1,200 miles or less.)In addition, NASA is authorized to develop an architecture for lunar communications and navigation, and must develop a strategy to implement a standardized lunar time to support operations and infrastructure on and around the moon.NASA must also continue to conduct research relating to advanced air mobility, unmanned aircraft systems (i.e., drones), and hypersonic technologies.Finally, the bill requires the Government Accountability Office to report on fire and emergency services at NASA launch and reentry facilities.
