If a meteoroid crashes into a planet, and no one is around to hear it, does it make a sound?
-esque “bloop” sounds are heard three times as the meteoroid enters the atmosphere, explodes into pieces, and slams into the surface.
“After three years of InSight waiting to detect an impact, those craters looked beautiful,” said Ingrid Daubar of Brown University, a co-author of the paper and a specialist in Mars impacts,. The team confirmed three other impacts had occurred. One on May 27, 2020 and two others on February 18 and August 31, 2021.

Mars is right next to our solar system’s main asteroid belt, which caused researchers to wonder why they haven’t detected more of these meteoroid impacts on the Red Planet. More meteoroids pass through Mars’ atmosphere without disintegrating since it is only about one percent as thick as Earth’s.
