NASA's new space policy chief Jared Isaacman confirmed what had been speculation for months: the Lunar Gateway's habitation modules suffered significant corrosion damage. The revelation came during congressional testimony about NASA's decision to halt Gateway development altogether, prioritizing lunar surface activities over the small orbital station.

The corrosion issues, which persisted for months, had been kept under wraps until Isaacman's disclosure. Both Northrop (builder of the HALO module) and Thales (builder of the I-HAB module) indicated the problems would be resolved by the end of Q3. The original Gateway launch was planned for 2022, but Isaacman testified the corrosion would have pushed deployment beyond 2030.

During his testimony, Isaacman questioned whether attempting repairs made sense at all. "I am not sure there is a deterministic approach to repair," he stated on social media, adding he was uncertain if efforts to fix HALO and I-HAB were "even warranted at this point." The manufacturers' optimistic timeline stands in stark contrast to his uncertainty about whether the modules can be salvaged.

Thales, historically the West's most important pressure vessel provider responsible for building Cygnus spacecraft structures for Northrop, now faces intensifying competition from American companies. While Axiom selected Thales for its private space station pressure vessels, Vast Space manufactures its station modules domestically in California, and Voyager has partnered with Vivace in Louisiana.
