"In 2011, a small meteorite was found in the Sahara Desert. Designated
Northwest Africa (NWA) 7034 or “Black Beauty”, the blackened chunk of volcanic
crystal turned out to be a little piece of Mars, flung into space by an
asteroid impact.
But where on Mars had it come from? If we knew that, the meteorite could give
us crucial clues into how our Earth-like neighbour had formed.
The red planet is covered in countless asteroid impact craters, and until
recently it seemed there was no way to tell which one was the home of Northwest
Africa 7034.
In new research, we sifted through more than 94 million craters to identify the
origin of the rocky Martian visitor: a crater in our neighbouring planet’s
southern hemisphere, created by an asteroid impact between 5 million and 10
million years ago."
