Scientists Find Rare Meteorite From Mars With Signs of Ancient Water

"I didn't think a rock like this existed on Earth," a geologist at the Lunar and Planetary Institute in Texas told the Washington Post. It looks like a polished rock, dark brown with a clay-colored stripe — but it's actually one of the oldest Mars meteorites ever found, blasted by an impact from the surface of Mars billions of years ago:

Technically speaking it's a collection of eight rock fragments, the largest of which is about the size of a fist. Nearly two pounds of the meteorite was discovered in the Sahara in Mali in 2022, and most is now held by a museum in Maine. Within two years, an initial examination determined the meteorite hailed from Mars; scientists are now finally digging deeper, with stunning results.
