Scientists identified a 4. 1-billion-year-old Martian meteorite, Teghaza 001, recovered from the Sahara desert in Mali, revealing details about the planet’s early mantle, crust and water history.

Earlier reports noted that the rose-colored stone, found in 2022, could be the oldest Martian rock on Earth and offered evidence of early liquid water on Mars. NASA later confirmed the sample as a Martian fragment, providing new insight into the planet’s early crust and water activity.
