Mars is an asteroid punching bag, NASA data reveals

Meteorite impacts pepper Mars at a rate up to 10 times more frequent than previous estimates, according to two new research papers that identified the seismic shock waves of these impacts detected by NASA’s now-defunct Mars InSight lander. The new rate is staggering. According to the findings, between 180 and 260 impacts per year occur […]
