Listen in to the surprising sounds of Mars getting dinged by a meteoroid.
and has recorded ‘“marsquakes” big and small on the red planet over the past few years. Listening in to the shaking of the planet gives scientists a better idea of what’s going on deep under the Martian surface.
It can also give them a glimpse of what’s going on in the planet’s immediate neighborhood, as the meteoroid research shows. Sounds from the rock hitting the atmosphere, exploding, and hitting the ground all shook the ground just enough to be picked up by InSight’s instruments. Researchers had been keeping an ear out for impacts from space rocks for a while in the InSight data, but September 5th, 2021, was the first time they noticed an impact using the instrument. With the information from InSight, scientists were able to pinpoint where they thought the rocks had crashed into the ground. When they sent a Mars Orbiter to check out the possible landing site, they found three craters.
“After three years of InSight waiting to detect an impact, those craters looked beautiful,” said Ingrid Daubar of Brown University in
