A 4.1 billion year old Martian meteorite is found in the Sahara. The space find was discovered back in 2022, but researchers have only now determined its age. According to them, the stone was formed in the Martian crust at least 4.1 billion years ago. If the estimate is confirmed, it may be the oldest of the 435 known Martian meteorites on Earth.
