NASA's Office of Inspector General dropped a pointed audit on April 20, 2026, warning that the agency's next-generation spacesuits may not be ready for a crewed lunar landing until 2031, three years after NASA's official 2028 target. The report, IG-26-006, examines what went wrong across four years of spacesuit development and why the U.S. now finds itself with a single provider, aging backup hardware, and a critical-path item for the Artemis III moonwalk that remains unproven. The 2031 figure is not a firm NASA schedule change. It is a statistical projection based on the historical average delay rate for major NASA flight programs. But the OIG's math is hard to ignore: if Axiom Space's AxEMU (Axiom Extravehicular Mobility Unit) follows the pattern of past programs, lunar and ISS suit demonstrations that were supposed to happen in late 2025 and early 2026 would slip to a date that is, at minimum, three years after the planned Moon landing and just one year before the ISS is scheduled for decommission.

The combined ceiling was $3.1 billion. The recipients were Axiom Space, a Houston-based commercial station startup, and Collins Aerospace, a defense and aerospace giant that had maintained NASA's legacy Extravehicular Mobility Units since the 1970s. The program had two goals. First, get new suits on the lunar surface for Artemis missions. Second, replace the aging EMU suits used at the International Space Station before its planned decommission around 2030. NASA designed xEVAS as a competition with two providers to build in redundancy and drive down costs through fixed-price contracts. Both goals, the OIG now concludes, were undercut by the program's own structure from the start.

The OIG describes those dates as "overly optimistic." Collins received a $97 million microgravity task order in December 2022 but immediately ran into schedule slippage, supply chain problems, and subcontractor issues. Its Preliminary Design Review was delayed by a full year. Despite those problems, NASA rated Collins' performance as "Excellent." By June 2024, NASA and Collins reached a mutual agreement to descope their task orders entirely. No hardware was delivered. NASA paid $37 million for four completed milestones before the work stopped. Collins retains its xEVAS IDIQ contract and could theoretically re-compete for future task orders, but for practical purposes, the program now has one suit provider and one option. The Scorecard at Program Exit • Collins Aerospace: 7M paid, zero hardware delivered, task orders descoped June 2024. • Prior development spending: $420M+ invested across earlier spacesuit programs before xEVAS launched. • NASA support to Axiom: $9M in additional testing and engineering support on top of task order payments. • Axiom payments to date: $228M+ across development milestones. One Company, One Suit, No Backup Collins' exit left Axiom Space as the only active xEVAS provider. The OIG's core concern is not that Axiom is incompetent. The concern is that NASA now has no redundancy for what is arguably the most human-critical component of any crewed lunar surface mission. An astronaut on the Moon is alive as long as the suit works. That suit, right now, exists as engineering articles and prototypes at Axiom's Houston facility. As of January 2026, Axiom is targeting late 2027 for suit demonstrations, a slip of more than 18 months from original program targets. The company completed a Critical Design Review in February 2026, which is genuine progress. Crew fit-check tests are ongoing. Axiom's CEO has publicly stated the company will be ready for the Artemis lunar surface mission. .1B Combined xEVAS contract ceiling 18+ mo Delay vs. original demo schedule 1 Active suit provider remaining 50 yrs Age of backup EMU suit design 2031 OIG worst-case demo projection 2028 NASA's Artemis III target date The OIG's 2031 projection is built on a specific methodology. The agency looked at the historical average delay rate across recent major spaceflight programs and applied that rate to xEVAS. The result: if Axiom slips at a pace consistent with how NASA's past programs have slipped, demonstrations would not occur until 2031. That is not a prediction, but it is a data-grounded warning that the current schedule carries significant downside risk. The fallback hardware is worrying. NASA's legacy EMU suits were designed in the 1970s. They are rated for microgravity ISS operations, not for the thermal extremes, dust abrasion, and mobility demands of the lunar south pole. Several EMUs have suffered in-suit water leaks in recent years. Using them as a backup for Artemis III is not a technical option, it would require substantial modification work the program has not scoped or funded. Four Structural Problems NASA Created for Itself The OIG's analysis goes beyond schedule. The report identifies specific acquisition decisions that created structural weaknesses in the program from day one.

Credit: AI illustration • Wrong contract type: Firm-fixed-price contracts work well for mature, well-understood products. They are poorly suited to developmental work where requirements evolve and unknowns are high. Spacesuit development falls squarely in the second category. When costs and unknowns rose, Collins had no mechanism to stay economically viable. Fixed price shifted risk to contractors in a domain where the government ultimately bears the mission consequences. • Limited bidder pool: NASA's requirement that each provider develop both a lunar suit and an ISS microgravity suit simultaneously narrowed the field significantly. Fewer companies had the resources and capability to bid on a dual-suit program. That structural choice limited competition before the program even started. • Ignored prior performance signals: The OIG notes that Collins had already drawn OIG scrutiny for EMU maintenance performance in a separate 2025 report (IG-25-012). Despite that history, NASA rated Collins "Excellent" on xEVAS milestones, a pattern the OIG describes as inconsistent with the objective record. • No interoperability standards: NASA has not established formal interoperability requirements between Artemis suits and the spacecraft and landers they will be used with. That gap means Axiom could deliver a functioning suit that requires expensive redesign work to connect to the Starship HLS airlock or the Orion vehicle. OIG Recommendations (NASA Concurred) • Seek industry input: Solicit broader feedback on xEVAS requirements before issuing future task orders to expand the potential bidder pool. • Establish interoperability standards: Define formal requirements for suit compatibility with Artemis vehicles including Starship HLS, Orion, and Gateway. What This Means for the 2028 Landing NASA Administrator Jared Isaacman told Congress last week that the agency is targeting two crewed lunar landings in 2028. The spacesuit question sits directly in that plan's critical path. Astronauts cannot walk on the lunar surface without a lunar-rated EVA suit. The Starship HLS can deliver them to the surface, but that capability becomes an orbit-and-observe mission if the suits are not ready.
