The "Insight" detector of NASA found 4 meteorites that hit Mars

Due to the thin and small asteroid belt near the solar system, Mars is more likely to be hit by meteorites than the earth.Recently, with the help of the "Insight" Mars probe, scientists have a more comprehensive understanding of Mars's characteristics.

Comprehensive Reuters and the Associated Press reported that the researchers reported on September 19 local time that the "Insight" detected the seismic waves and sound waves generated by 4 meteorites in the impact of Mars, and then calculated the position of the meteorite pit they left.Scientists perform such measures for the first time outside the earth.

Researchers describe the basic situation of 4 meteorites.One landed in Mars in 2020, and the other three landed in Mars in 2021; their size is relatively moderate, weighs about 200 kg, diameter is about 50 cm, and the left meteor pit is about 7.2 meters wide.Their landing site is between 85 kilometers and 290 kilometers from the "insight".One of them exploded into at least three pieces after landing, and each piece of fragment left its own meteorite pit.
