We Now Know Exactly Which Crater the Martian Meteorites Came From

Post by fred8615 »

Mars is still quite mysterious, despite all we’ve learned about the planet in recent years. We still have a lot to learn about its interior and surface evolution and how changes affected the planet’s history and habitability. Fortunately, an impact on the red planet sent clues to Earth in the form of meteorites.

The geological information contained in these meteorites would be even more valuable if we knew exactly where they came from. A team of researchers say they’ve figured it out.

According to a new study, the Martian meteorites came from Tooting crater, a large crater in Mars’ Tharsis region. The Tooting crater is 28 km (17 mi) in diameter and 1200 meters (3900 ft) deep. It’s only a million years old, which is young for an impact crater.

The new study is titled “The Tharsis mantle source of depleted shergottites revealed by 90 million impact craters.” It’s published in the journal Nature Communications. The lead author is Dr. Anthony Lagain, from Curtin University’s Space Science and Technology Centre in the School of Earth and Planetary Sciences.
