Scientists have discovered haematite, a form of rust, on the Moon’s poles. The finding puzzles researchers since rust needs oxygen and water, both scarce on the Moon. Studies suggest Earth’s atmosphere and magnetic effects may play a role.

- 2020 Chandrayaan-1 had earlier spotted haematite near poles
- Findings suggest Earth–Moon material exchange over time
- Insights may aid future lunar missions and equipment design
