Hear a Meteoroid Striking Mars

September 26, 2022

NASA’s InSight lander detected seismic waves from a meteoroid and was able to capture the sound of the space rock striking the surface of Mars for the first time. The meteoroid – the term used for incoming space rocks before they hit the ground – entered Mars’ atmosphere on Sept. 5, 2021, exploding into at least three shards that each left craters behind. Mars’ atmosphere is just 1% as dense as Earth’s, allowing far more meteoroids to pass through and impact the Red Planet’s surface.
