NASA Administrator Jared Isaacman recently revealed that two habitation modules for the Lunar Gateway had suffered from corrosion, sparking a wave of doubt among industry observers. Northrop Grumman, the primary contractor, acknowledged a manufacturing irregularity, while Thales Alenia Space, which provided components to both modules, admitted to similar issues in its own structures.

The French-Italian firm stated that it is working with NASA and its customers to address these metallurgical behaviors by the end of 2026. It cited past experience from the International Space Station as a reassurance for future success, emphasizing its ability to handle such challenges.

Axiom Space, which also ordered a pressurized structure from Thales, echoed similar concerns, adding that it too had experienced similar issues with Module 1. The company stressed the resilience of space station components despite past corrosion problems, highlighting their continued functionality after two and a half decades in orbit.

The Gateway project, while ambitious, faces significant challenges as it moves forward. These include not only the technical aspects but also the financial implications of addressing these issues before launching the modules into operation. The revelation underscores the complexities of building infrastructure for long-term space habitation.
