Solving the mystery of meteorites coming from Mars

Six Martian Meteorites It can be traced back to the craters from which it erupted millions of years ago. The discovery should help researchers learn more about the Red Planet.

If a meteor from space hits Mars, it will cause an explosion. Debris overcomes the planet's gravity. It could. These meteorites could eventually hit Earth. Anthony Lajean of Curtin University in Australia and his team have now identified these planetary fragments in Martian craters.

Choose from 80,000 holes.

“There are about 80,000 craters on Mars that are more than 3 kilometers in diameter,” Lagin says. “Any of these craters could be the origin of Martian meteorites.” New Scientist Quoted. However, the researchers' model narrowed the possibilities to 20 holes. Age of meteorites It is coordinated with the age of the drill.

The researchers then examined Meteorite structureTo find out what force they were subjected to when they were thrown into space. They also entered this information into the form. So they were able to identify some of the candidates from which they chose… 5 holes as favorite Selected.

Meteorites are made of lava rocks.

All meteorites are pieces. solidified lavaIf the craters are indeed the origin of the meteorites, we can learn a lot about the volcanic nature of Mars. Two meteorites that came from the same crater suggest that the area Volcanically active for a longer period It was previously assumed.

So far, only 200 Martian meteorites have been found on Earth. They are the only Martian rock that researchers can examine in close, detailed detail. However, that should change in the future. In Mars Sample Return Missions Mars samples are scheduled to be returned to Earth from the Red Planet.

Space organizations NASA and ESA For example, we are working together on such a task, but financial challenges continue to hinder the project. Chinese Space Agency CNSA It is also planning a sample return mission. This is scheduled for around 2030.
