NASA Administrator Isaacman defends FY2027 budget and moon base plans

Purpose

The House Science, Space, and Technology Committee held this hearing to examine the Trump administration's fiscal year 2027 budget request for NASA — a proposed $18.8 billion, roughly a 23% cut from FY2026 enacted levels0:17:25 — and to question new NASA Administrator Jared Isaacman on the agency's recently announced "Ignition" initiatives, including a lunar south pole base, a nuclear Mars demonstration mission, and a new government-built ISS module. The hearing came weeks after the successful Artemis 2 mission, and members from both parties pressed the administrator on proposed cuts to science, aeronautics, and STEM programs, as well as NASA's compliance with congressional appropriations law.

Who spoke

Chairman Brian Babin (R-TX)0:14:21: Opened by praising the Artemis 2 mission0:14:50, criticized the 23% NASA budget cut as unsupportable0:17:53, and pressed Isaacman on backup plans if SLS/Orion alternatives are delayed before the 2028 lunar landing goal0:34:44.

Rep. Blake Moore / "Dr. Kennedy" (R-UT)2:39:23: Highlighted Northrop Grumman's Utah-built SLS boosters (75% of Artemis 2 thrust)2:39:53 and asked about the SR1 Freedom nuclear power/propulsion demonstration as a cost-saving example2:40:12.

Rep. Dean Whitesides / "Whiteside" (D-CA)2:45:05: Called the OMB budget "dead on arrival," secured a commitment to follow appropriations law2:46:25, praised aeronautics and JPL, and raised concerns about risks of extending ISS to 2035–2040 if a new station module isn't ready until 2029–20302:48:56.

Rep. Jay Obernolte (R-CA)2:50:02: Asked about JPL layoffs and funding restoration2:50:38, the lunar terrain vehicle program's adequacy2:52:41, and space weather research collaboration2:54:14.

Rep. Josh Riley (D-NY)2:55:22: Highlighted Unison Industries in Norwich, NY, which built Artemis 2's ignition systems, and invited Isaacman to visit2:58:22.

Rep. Rich McCormick (R-GA)3:00:16: Joked about wanting to fly to space3:00:24, asked about STEM pipelines with Georgia Tech3:01:26 and justification for a government-owned ISS successor module versus accelerating commercial LEO transition3:03:03.

Key moments

Isaacman disclosed that GAO's 2025 assessment found roughly $15 billion in cost overruns across major NASA projects since 2009, citing Dragonfly ($850M to $3.4B) and the X-59 ($468M to nearly $800M) as examples0:26:330:26:57.

Lofgren entered into the record a May 30, 2025 internal NASA email announcing an "orderly shutdown" of the Electrified Powertrain Flight Demonstration project the same day the FY26 budget was released, calling it "smoking gun evidence" NASA implemented the president's budget before congressional approval0:39:420:40:40.

Isaacman acknowledged more than 40,000 of NASA's roughly 55,000-person workforce are full-time contractors costing over $4 billion a year, and said center directors are determining which roles convert to civil service0:37:58.

Isaacman said Gateway's only delivered habitable modules (aside from the power/propulsion element) arrived corroded, justifying redirecting Gateway funds toward a lunar surface base instead3:33:00.

Isaacman revealed NASA canceled a spaceport operations solicitation with Alaska's NANA Regional Corporation the day before the hearing, without yet knowing the reason3:09:19.

Rep. Whitesides warned that NASA's proposed new ISS government module likely couldn't launch before 2029–2030, risking a de facto ISS extension to 2035–2040 that could consume $10–20 billion needed for exploration2:48:56.

Sharp exchange between Rep. Bill Foster and Isaacman over propulsion technology: Foster argued Hall thrusters lack the impulse needed for crewed Mars missions and pushed for nuclear thermal propulsion investment; Isaacman said NASA must first "get nuclear out of the lab" after $20 billion in past failed programs before scaling NTP3:19:383:20:58.

Isaacman said the canceled Mars Sample Return mission cost taxpayers $2 billion with nothing to show, and NASA still spent $200 million maintaining it in formulation after the prior administration's cancellation0:30:163:57:28.

Multiple Democrats (Sykes, Rivas, McBride) repeatedly pressed Isaacman on the proposed elimination of the statutorily authorized Office of STEM Engagement; Isaacman maintained internship and grant funding exists independently across NASA's mission directorates3:41:033:42:43.

McBride noted NASA's FY2025 spend plan arrived six months late and the FY2026 plan remains overdue past its 45-day statutory deadline; Isaacman said NASA's portion was completed in early April and is pending administration review3:46:383:47:15.
