## Key points

- Teghaza 001 preserves signs of water interacting with Mars’ crust.
- The meteorite formed early in the planet’s history.
- Its chemistry may shed light on how Mars lost water.

## Summary

Studies of the ancient Martian meteorite Teghaza 001 have revealed chemical traces of water interacting with rock in Mars’ early crust. The findings matter because they offer evidence about the planet’s watery past and may help scientists understand how it changed from a world with liquid water to today’s cold, dry environment.

Recovered in the Sahara, the meteorite formed about 500 million years after the solar system began. Tiny apatite crystals preserve hydrogen signatures from both Mars’ interior and its ancient hydrosphere, pointing to an early exchange between deep magma and surface water. Researchers say the rock may also retain clues about the Martian atmosphere as the planet was losing water.
