Title

NASA's ISS-to-commercial-station transition and a new core-module plan

Purpose

The House Science, Space, and Technology Subcommittee on Space and Aeronautics held this hearing to examine the safety and readiness of the International Space Station through its planned 2030 retirement and NASA's strategy for transitioning research and crew activity to commercial low Earth orbit (LEO) platforms. The hearing came one day after NASA Administrator Jared Isaacman announced a potential new option — a government-owned core module attached to the ISS — adding urgency to members' questions about cost, timeline, and risk of a gap in U.S. human presence in LEO. Witnesses from NASA, the Commercial Space Federation, and the Aerospace Safety Advisory Panel testified on the ISS's aging systems, market viability of commercial stations, and acquisition strategy.

Who spoke

Chairman Herodopoulos0:07:41: Opened the hearing on America's future in LEO, noted the ISS is directed to operate through 2030 with de-orbit in 20310:09:25, and framed China's growing space station as a competitive challenge0:10:54; later pressed Montalbano on the Russian segment's structural cracks and shared de-orbit costs1:15:591:18:33.

Ranking Member Fuchi (Valerie Fuschi)0:11:40: Said NASA "lacks a clearly defined and executable path" to CLLD transition per ASAP's latest report0:24:48, flagged the newly announced potential changes0:15:47, and entered a Hill op-ed on NASA's economist cuts into the record0:16:07; later pressed Montalbano on whether NASA has done its own market analysis1:20:30.

Chairman Brian Babin (R-TX), Full Committee0:16:28: Detailed the ISS's Johnson Space Center management0:16:58 and criticized the Biden administration for funding the de-orbit vehicle through a disaster supplemental rather than a budget request, straining ISS operations funds0:18:22; noted Congress's "one big beautiful bill" provided $1.2 billion for space operations0:18:52.

Ranking Member Lofgren, Full Committee0:21:33: Cited the Boeing Starliner mishap and a damaged cargo vehicle as recent challenges0:23:22, and warned the U.S. risks "footing the bill as the primary customer for privately-owned space stations that may be less capable than the ISS"0:24:33.

Joel Montalbano, NASA Acting Associate Administrator for Space Operations0:26:28: Testified the current single-provider CLLD approach is "very risky"0:49:04 and described NASA's new option of a government-procured core module attached to the ISS where up to two commercial partners could develop capabilities before separating0:49:57; said transportation alone costs ~$2 billion/year and total ISS operations run just over $3 billion/year0:58:580:59:38; detailed the Russian segment's "PrK" leak area and mitigation steps1:16:21; said de-orbit costs will be shared based on partner segment mass1:18:44.

Dave Cavossa, President, Commercial Space Federation0:31:09: Said NASA's newly announced potential changes are "sewing confusion" among commercial companies0:31:48 and industry has raised over $1 billion in private capital in six months0:32:16; disputed NASA's white paper claiming no verifiable market exists0:52:53; recommended NASA invoke Public Law 85-804 for liability indemnification0:34:36.

Charlie Precourt, Member, Aerospace Safety Advisory Panel0:36:19: Said the ISS is in "the highest risk phase of its life cycle"0:37:14 and warned of a "credible risk of a gap in human spaceflight capability" post-ISS0:37:44; said the Starliner case showed "ambiguity in risk ownership and safety governance" tied to contract structure0:38:44.

Rep. George Whitesides (D-CA)0:55:49: Questioned whether the new core-module option means NASA continues operating ISS beyond 2030, undercutting cost savings goals0:58:07; disputed Montalbano's transportation cost comparison, citing Crew Dragon's proven cost savings1:00:41; questioned the module's 10-year typical build timeline versus the ISS's remaining life1:32:48 and warned NASA risks losing private investors' trust1:36:04.

Rep. Daniel Webster (R-FL)1:01:06: Asked whether the ISS should be treated as one object or individual modules for liability purposes1:01:06 and about limiting UN/international court roles in space disputes1:03:58.

Rep. Maxine Dexter (D-OR) [Miss Selenus in transcript]1:04:42: Asked how the year-long gap before Isaacman's confirmation affected industry certainty1:05:09; asked about funding uncertainty's impact on capital-raising1:07:15 and STEM engagement through the ISS program1:38:02.

Rep. Vince Fong (R-CA)1:09:48: Asked about the biggest challenges to a government-to-private LEO transition, with Cavossa citing the need for "certainty"1:10:17; asked about China's Tiangong station capabilities1:10:51 and regulatory barriers including indemnification1:12:59.

Key moments

NASA revealed a new potential option, announced the day before the hearing: a government-procured core module attached to the ISS that up to two commercial partners could dock to, develop on, and later separate from to become independent stations0:49:281:26:17.

Cavossa said industry considers the new plan reminiscent of "Lucy and Charlie Brown with the football," warning NASA may now build its own core module competing with industry after companies spent years designing stations to different requirements0:33:040:33:21.

Babin cited a NASA white paper stating that after 25 years of commercial use, "no breakthrough products are scalable in space manufacturing markets" and tourism "has not materialized as a meaningful market" — Cavossa disagreed, citing billions raised and unannounced deals0:52:220:52:53.

Whitesides and Montalbano sparred over costs: Montalbano said transportation costs (~$2 billion/year) and operations (~$3 billion/year total) would persist under any station model, while Whitesides argued commercial crew proved private-sector costs are dramatically lower0:58:461:00:41.

Montalbano disclosed NASA's commercial payload pricing rose from $3,000/kg to $20,000/kg after being told to stop subsidizing the industry — and "nobody's taken us up on that" since1:20:581:21:26.

Precourt testified ASAP's 2025 annual report found NASA "lacks a clearly defined and executable path to transition to a CLLD before or immediately after the ISS end of life," creating a credible risk of a capability gap0:37:44.

Montalbano detailed the Russian "PrK" segment's structural leak concerns: crews minimize time in the pressurized area, close the hatch between US and Russian segments, and plan to reroute docking to another port1:16:211:17:54.

Whitesides pressed Montalbano on the core module's feasibility, noting NASA modules "normally take like 10 years to build," raising doubts about the timeline given ISS's 2030 retirement1:32:481:33:14.

Cavossa said one commercial partner, ISS National Labs, reported its project backlog will cover ISS use through 2030 and beyond within 8–12 months1:39:50.

Babin noted NASA is issuing initial RFIs for the new core-module transportation and destination concepts today, with final RFI in late April and RFPs by June0:51:26.
