The leading hypothesis suggests that the smell resulted from a chemical reaction between the 'chemically hungry' lunar dust, with its dangling bonds, and the oxygen and moisture inside the cabin.
The Frontline Impact
How this affects you
The chemical reactivity of lunar dust, which likely caused the smell, poses significant hazards for human health and equipment, necessitating advanced filtration, suit design, and medical monitoring for future lunar missions like Artemis.
