Exactly. Say you land on the Moon and your ship sticks around for a few months. Micrometeorites can impact and cause minor damage to the surface cooling system.

Exactly. Say you land on the Moon and your ship sticks around for a few months. Micrometeorites can impact and cause minor damage to the surface cooling system. You’re baked at that point. But given the hull is stainless steel repairs are much easier. Any experienced welder can spot repair divots and holes or weld in much larger patches. No need to worry about the specially constructed parts required for evaporative cooling. Fix the hull then install replacement tiles.
