Well, this is embarrassing: The Lunar Gateway's primary modules are corroded

Corrosion was found on NASA’s Lunar Gateway HALO module, prompting an investigation into materials and manufacturing as likely causes.

ESA said the issue appears manageable, and the I-HAB module is still under construction.

Axiom Space later confirmed a similar corrosion problem on its first station module.

The findings could complicate Gateway schedules and affect European participation in the Moon program, with broader station-program implications.
