Nationalgeographic.co.id—Planetary researchers from the Space Science and Technology Center at Curtin University have identified the meteorite’s origin crater Mars the famous. Their analysis pinpointed the origin of the Mars Northwest Africa (NWA) meteorite 7034, better known as ‘Black Beauty‘.
According to their identification, the meteorite came from a crater in the northeastern province of Terra Cimmeria-Sirenum in the southern hemisphere of Mars. The meteorite exited between 5 and 10 milliom years ago before reaching Earth.
The full report of this study was published in the journal Nature Communications by title “Early crustal processes revealed by the ejection site of the oldest martian meteorite” not too long ago. The publication is open access that can be obtained online.
As is known, NWA 7034 or ‘Black Beauty’ weighing about 320 grams is breccia regolith from Mars which was discovered in the Moroccan Sahara desert in 2011. NWA 7034 contains the oldest known Martian frozen matter, dating back about 4.5 billion years.
“Black Beauty is the only Martian brecciation (breakdown zone) sample available on Earth, which means it contains angular fragments of several types of rock cemented together that differ from all other Martian meteorites that contain a single rock type,” said researcher Anthony Lagain.

For the first time, he said, they were able to work out the geological context of the only sample of Martian breccia available on Earth.
“10 years before NASA’s Mars Sample Return mission is set to send back samples collected by the Perseverance rover currently exploring the Jezero crater.”
Lagain and colleagues analyzed a very large volume of high-resolution planetary images via machine learning algorithms to detect impact craters. They used supercomputers at the Pawsey Supercomputing Research Centre, and Curtin HIVE (Hub for Immersive Visualization and eResearch).
