Sahara meteorite offers rare look at Mars' ancient crust

A Martian meteorite called Teghaza 001, found in Mali's Sahara Desert in 2022, formed at least 4.1 billion years ago, a team led by NASA Jet Propulsion Laboratory scientist Yang Liu has shown. Old Martian rocks are rare on Earth, and unlike the mixed Black Beauty meteorite, Teghaza 001 is a single, intact igneous rock from the planet's early crust.
