Why
The leading hypothesis suggests the smell was caused by a chemical reaction that occurred when the reactive lunar dust, with 'dangling bonds' from exposure to space, met oxygen and moisture in the cabin.
The Frontline Impact
How this affects you
The chemical reactivity of lunar dust, which likely caused the smell, poses significant challenges for future lunar missions like Artemis, including risks to human health and equipment damage, making effective dust handling crucial for long-duration stays.
