Famous Mars crater that ejected a meteorite with 4.4 billion year old fragments identified by artificial intelligence in stunning image
- Researchers used machine learning to identify the crater on Mars from which the ancient Black Beauty meteorite flew.
- The meteorite contains the oldest Martian fragments ever found, at 4.48 billion years old, and it shows similarities between the very old crust of Mars and the Earth’s crust.
- “We’re also adapting the algorithm that was used to determine the Black Beauty’s ejection point from Mars to reveal other secrets of the Moon and Mercury.”
- The researchers named a specific crater on Mars after the city of Karratha, which contains one of the oldest earth rocks.
A new study that harnessed the power of artificial intelligence has identified a specific crater on March which was thrown by the ancient meteorite Black Beauty.
The researchers named the Martian crater after the Australian city of Karratha, which contains one of the oldest terrestrial rocks.
The discovery offers unknown details about the Martian meteorite NWA 7034, nicknamed “Black Beauty”, which researchers say was found in Africa in 2011.
“For the first time, we know the geological context of the only Martian breccia sample available on Earth,” says Dr. Anthony Lagen. The image shows the distribution of 90 million craters on the surface of Mars, obtained using the crater detection algorithm.
“For the first time, we know the geological context of the only Martian breccia sample available on Earth, 10 years before NASA’s Mars return mission is due to send back samples collected by the Perseverance rover, which is currently exploring Jezero Crater,” Lead Author doctor . Anthony Lagaine of the Curtin University Center for Space Science and Technology in the School of Earth and Planetary Sciences speaks in statement.
Brecciated simply means that the meteorite contains angular fragments of several rock types cemented together, which makes it unique – all other Martian meteorites contain the same rock type.
Powerful supercomputers have allowed scientists to identify the crater on Mars from which the famous meteorite flew.

On the right is the dataset and methods used to determine the location of the meteorite ejection.
“Finding the area where the Black Beauty meteorite formed is critical because it contains the oldest Martian fragments ever found, which are 4.48 billion years old, and shows similarities between the very old Martian crust, which is 4.48 billion years old. about 4.53 billion years, and today’s terrestrial continents, says Lagain.
“The region we identify as the source of this unique Martian meteorite specimen represents a veritable window into the planets’ earliest environment, including Earth, which our planet lost to plate tectonics and erosion.”
Mars is the fourth planet from the Sun with a “nearly dead” dusty, cold, desert world with a very thin atmosphere.
Mars is also a dynamic planet with changing seasons, polar ice caps, canyons, dormant volcanoes and evidence that it was even more active in the past.
This is one of the most studied planets in the solar system and the only planet that people have sent rovers to explore.
One day on Mars lasts just over 24 hours, and a year is equal to 687 Earth days.

The researchers used one of the fastest supercomputers at the Pawsey Supercomputing Research Center and Curtin University’s Center for Immersive Imaging and Electronic Research to analyze a huge amount of high-resolution images using machine learning to detect craters.
“We’re also adapting the algorithm that was used to pinpoint the Black Beauty’s ejection point from Mars to unlock other secrets of the Moon and Mercury,” study co-author and Professor Gretchen Benedix, also of the Curtin Center for Space Science and Technology at the School. Earth and planetary sciences, explains.
The researchers note that the Earth’s geological record of how it formed and differentiated has been largely destroyed by its evolution.
However, we can get some clues from studying other planets.
“We can investigate [Mars] with the spacecraft, and the samples are available for in-depth analysis on Earth in the form of Martian meteorites, says Benedix.
“This will help unravel their geological history and answer burning questions that will help future exploration of the solar system, such as the Artemis program to send people to the Moon by the end of the decade, or the BepiColombo mission in orbit around Mercury in 2025. .’

The researchers hope to use this discovery to learn more about the evolution of the Earth. Pictured: Karratha crater on Mars (center) inside Dampier crater.
