Welcome back to Tech Vault. NASA's InSight mission touched down on Mars in November 2018 to peer inside the planet, mapping its layers and faultlines. And on Dec. 24, 2021, the lander made a remarkable detection, catching seismic waves from a sizable meteoroid impact. Photos taken from orbit made the signal even more intriguing, because scientists tied the seismic detection to the sight of a large, fresh crater.
Working backward from the size of the crater, scientists estimated that the asteroid that slammed into the Red Planet was between 16 feet (5 m) and 40 feet (12 m) wide before it met its fate. Had it struck Earth, a rock of that size would likely have burned up in Earth's atmosphere, but Mars' thin atmosphere doesn't do much to protect the surface. Thanks to the meteor's size, the impact dug deep enough into the Martian surface to throw up boulder-size chunks of rock and water ice. Check this video out!
