Lunar Gateway modules show corrosion, pausing program

The Lunar Gateway's primary habitable modules, HALO and I-HAB, have been found to be corroded. This discovery is a significant factor in NASA's decision to pause the Gateway program. Corrosion was confirmed by NASA Administrator Jared Isaacman during Congressional testimony. Both modules, built by Thales Alenia Space for Northrop Grumman and the European Space Agency respectively, exhibit this issue. Northrop Grumman is repairing the HALO module, citing a "manufacturing irregularity." The European Space Agency stated preliminary findings suggest a combination of factors, including materials and processing, caused the corrosion.
