NASA Transition Authorization Act of 2025
Latest action. Committee on Commerce, Science, and Transportation. Ordered to be reported with an amendment in the nature of a substitute favorably.
NASA Transition Authorization Act of 2025
This 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.

Where is it in the process, and what happens next?
4 steps remain before this bill could become law.
The record's latest action, on March 4, 2026: Committee on Commerce, Science, and Transportation. Ordered to be reported with an amendment in the nature of a substitute favorably.
- Clearing the committees it was referred to, and being scheduled for a floor vote
- Passage by the Senate
- Passage by the House
- The President's signature. If the President vetoes it, two-thirds of both chambers must vote to override.
How likely is it to become law?
Civibrief does not forecast outcomes and this page has no opinion about this one. What the record supports is a base rate, which is a fact about the whole pile, not a prediction about this measure.
In the 118th Congress (2023-24), 274 of the 16,565 bills and joint resolutions introduced became law, about 1.7 percent. That count covers every measure at every stage, including the many that never left committee.
This one is not there yet: 4 steps are still outstanding, listed above.
Has anyone actually voted on it?
No. No roll call in this Congress cites this measure. That is the ordinary outcome: most measures never reach a recorded floor vote, and a committee ends most of them simply by not acting.
A vote is not the only thing that happens to a measure. Hearings, markups, and referrals are all recorded actions, and none of them is a vote of the full chamber.
Who is behind it?
Ted Cruz (R-TX) introduced it on March 11, 2025, and 6 members have since signed on as cosponsors.
They come from both major parties: 4 Democrats, 2 Republicans.
Cosponsoring is a formal signature on the text. It is not a commitment to vote for the measure, it does not bind anyone's party, and a long list of cosponsors is a measure of attention rather than of prospects.
How long has it been in play?
It was introduced on March 11, 2025, 548 days ago. The most recent recorded action was 190 days ago, on March 4, 2026.
Measures do not carry over. Anything the 119th Congress has not finished by January 3, 2027 dies when the term ends, and has to be introduced again from the start in the next Congress.
Every answer above is assembled from this measure's own record on Congress.gov and from published counts of what Congress has passed before. Civibrief does not predict outcomes and takes no position on any measure.
