NASA’s InSight lander captured the ‘bloop’ sound of a meteor falling to Mars

Nobody had ever heard the sound of a meteor crashing into another planet until NASA’s InSight lander recorded the seismic waves of a space rock striking Mars.

On September 5, 2021, a rock hurtling through space crossed the red planet’s path. The meteor screamed towards the planet’s dusty orange surface, sending a shock wave through the atmosphere.

Though it may have burned up from the friction and heat of plowing through Earth’s atmosphere, the meteor survived the thin Martian air. It splintered into at least three pieces, which crashed into the planet’s surface and made craters.

The InSight lander’s seismometer, designed to measure Mars quakes and dust devils, was sensitive enough to detect the acoustic impact of the shock wave hitting the ground as well as the seismic waves from the meteor’s crash landing. NASA shared audio of the whole event on Monday. Take a listen below.

“Strangely, it’s more like a ‘bloop’ than a ‘bam!'” science writer Corey Powell said on Twitter.

NASA’s Mars Reconnaissance Orbiter, a satellite orbiting the planet, later captured images of the impact craters from the meteor.

“After three years of InSight waiting to detect an impact, those craters looked beautiful,” Ingrid Daubar, a specialist in Mars impacts at Brown University, said in a NASA press release.

Since then, scientists have combed through …read more
