4-billion-year-old 'Rosetta Stone' found in Sahara Desert could unlock the secret history of water on Mars

A remarkably old meteorite, dating back over 4.1 billion years, has been unearthed within the Sahara Desert, representing one of the earliest Martian meteorites identified to date. This geological specimen provides scientists with an unprecedented opportunity to study the origins of Mars’ initial crustal structure. Researchers believe this rock holds crucial information regarding the planet’s development during its formative stages. Specifically, the meteorite offers insights into potential interactions between early Mars and water sources. Analysis of the rock's composition could significantly advance our understanding of how liquid water shaped the Red Planet billions of years ago, potentially revealing details about ancient environments.
