Story summary
- A study finds Earth's oxygen can oxidize lunar iron to hematite, challenging assumptions.
- Hematite is found at the lunar poles where water exists, linking Earth to lunar chemistry.
- Experiments show oxygen ions from Earth's magnetosphere can oxidize iron under lunar conditions.
- During full moons, the Moon may receive more oxygen as solar wind is blocked; Artemis missions could yield samples.
