Senate-House Standoff Over NASA Reauthorization Threatens Moon-Base Timeline

Negotiations between the Senate Commerce Committee and the House Science, Space and Technology Committee have stalled, leaving the reauthorization of the National Aeronautics and Space Administration (NASA) in limbo as President Donald Trump prepares to visit the Johnson Space Center on Friday. The split jeopardizes the administration’s priority of establishing a permanent lunar outpost under the Artemis program, an effort outlined in a December executive order that calls for initial moon-base elements by 2030.

Trump’s order builds on Artemis, which aims to return humans to the Moon and sustain a presence there. Earlier this year, NASA announced a $20-billion plan to build a base near Shackleton Crater at the lunar south pole. The agency has not received a full reauthorization since 2017; a “mini” bill passed in 2022 provided limited authority. In parallel, the president signed a memo targeting at least 1,000 commercial U.S. space launches and re-entries by 2030, up from fewer than 200 launches in 2025.

The Senate bill, approved by the Senate Commerce Committee in March with bipartisan support, proposes a two-year reauthorization, embeds language for the moon-base project, and extends International Space Station (ISS) operations through 2032. Senate Republicans, led by Sen. Ted Cruz (R-Texas), argue that continuous ISS staffing upholds longstanding U.S. policy.

The Hill

The House version, championed by Rep. Brian Babin (R-Texas) and passed in February, offers a one-year reauthorization and omits the moon-base provision. House negotiators warn that a two-year authorization could be harder to pass under the Senate’s “suspension calendar” and contend that obligating NASA to fund the ISS for billions of dollars annually would divert resources from commercial low-Earth-orbit successors.

The Hill

Mike French, founder of the Space Policy Group and former NASA chief of staff, observed that the Senate bill aligns more closely with Administrator Jared Isaacman’s vision, while the House bill emphasizes oversight and reporting.
