Researchers used AI to pinpoint the meteorite’s crater on Mars’ southern hemisphere, naming it Karratha, a city close to the Pilbara region
Artificial intelligence has helped pinpoint the exact origin site of the oldest Martian meteorite, in a discovery researchers say provides clues about the planet’s early history.The meteorite, commonly known as “Black Beauty” and officially called Northwest Africa 7034, contains the oldest known Martian igneous material, which is approximately 4.5bn years old. It was found in the Sahara Desert in 2011.
The meteorite’s origin crater on Mars has been named Karratha, after the Western Australian mining town – in keeping with naming conventions set out by the International Astronomical Union that stipulate small craters must be named after cities on Earth with a population less than 100,000. Of 19 candidate craters, the team narrowed the origin site down to one that had characteristics matching the meteorite’s properties.
