CNN —Hundreds of basketball-size space rocks slam into Mars each year, leaving behind impact craters and causing rumblings across the red planet, according to new research. During its time on Mars, InSight used its seismometer to detect more than 1,300 marsquakes, which take place when the Martian subsurface cracks due to pressure and heat. Meteoroids are space rocks that have broken away from larger rocky bodies and range in size from dust grains to small asteroids, according to NASA. “We’re interested in studying that on Mars because we can then compare and contrast what’s happening on Mars to what’s happening on the Earth. Between 280 and 360 meteoroids hit the red planet each year, and they form impact craters larger than 26 feet (8 meters) across, according to the study.
