Briefings

Scientists analyzed Chang'e-6 lunar samples and discovered magnetic minerals that record ancient magnetic activity, providing evidence that the moon's global magnetic field has long since disappeared. This research helps explain the moon's magnetic field evolution. The findings are based on magnetic mineral analysis of Chang'e-6 samples collected in 2024, with data available from September 2026.

Key points

• Lunar magnetic minerals in Chang'e-6 samples preserve records of ancient magnetism, indicating the moon's global magnetic field has ceased to exist.

Context and limitations

Data is limited to Chang'e-6 samples; magnetic mineral analysis provides indirect evidence of past magnetism rather than direct measurement of the field's current state.
