Negotiations between Republican leaders in the House and Senate over a bill to reauthorize NASA have stalled. The legislative disagreement occurs as President Trump is scheduled to visit the Johnson Space Center in Houston on Friday to award the Congressional Space Medal of Honor to the Artemis II crew. The dispute centers on different visions for the agency’s priorities, specifically concerning the establishment of a permanent moon base and the operational timeline of the International Space Station (ISS).
The legislative delay follows a December executive order from President Trump directing NASA to establish moon base elements by 2030 through the Artemis program. Earlier this year, NASA Administrator Jared Isaacman announced a $20 billion plan to build this lunar base, aiming for crewed landings every six months. The Senate Commerce Committee passed a bipartisan reauthorization bill in March that aligns with this vision, but the House Science Committee's version passed in February did not include the same provisions.
Key points of contention involve the location and funding of lunar operations. The Senate bill includes language to begin work on a base near the Shackleton crater at the moon's south pole and seeks to extend ISS operations through 2032. House negotiators have raised concerns about the long-term costs of a moon base before the concept is fully vetted. They also argue against a mandate to fund the ISS through 2032, suggesting those billions of dollars might be better used elsewhere.
The scale of the proposed lunar project is valued at roughly $20 billion. For the U.S. space industry, the lack of legislative consensus could impact the goal of reaching 1,000 commercial launches and reentries by 2030, a significant increase from the fewer than 200 launches recorded in 2025. Failure to pass a bill before the end of the 119th Congress could also mean that if control of the House shifts following the midterm elections, the authorization process may have to restart.
A person close to the House Science Committee stated that negotiators are still "trading paper" in an attempt to reach an agreement before Christmas. If the House and Senate cannot reconcile their differences, the Artemis program’s schedule for a 2030 base construction could be delayed. The next steps involve further committee talks as the 119th Congress nears its conclusion.
