InSight detects meteorite seismic and audio waves and calculates crater locations.
NASA's InSight lander is helping scientists grasp this Martian feature.
Researchers on Monday detailed how InSight detected seismic and acoustic waves from four meteorites hitting its surface and determined the position of the craters they left.
NASA's Mars Reconnaissance Orbiter confirmed the crater locations.
These seismic measurements provide us a new instrument for studying Mars or any other planet we can deploy a seismometer on, said InSight's main investigator.
InSight tracked one small space rock in 2020 and three in 2021.
Mars has 1% of Earth's atmosphere. Between Mars and Jupiter is the asteroid belt.
InSight's seismometer detected 1,300 quakes on Mars.
