Two microphones aboard the Perseverance Rover have “recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel and motors whirring as the spacecraft moves its arm,” NASA says.
NASA has launched an interactive resource that allows listeners to hear recordings taken millions of miles away on the surface of the Red Planet.
Although it’s subtle, you don’t have to be a planetary scientist to hear the difference between sounds on Earth and sounds on Mars.
“If you hear one new thing today, how about making it the sound of wind on Mars?”

NASA describes the astro-acoustics of Mars this way: If you were standing on Mars, you’d hear a quieter, more muffled version of what you’d hear on Earth, and you’d wait slightly longer to hear it.
Baptiste Chide is a planetary scientist who is studying the audio’s data at L’Institut de Recherche en Astrophysique et Planétologie in France.
“Martian sounds have strong bass vibrations, so when you put on headphones, you can really feel it.
“It sounds even better if you listen through headphones”

I think microphones will be an important asset to future Mars and solar system science,” Chide says.
David Gruel, one of the experts who study the rover’s audio, says wind on Mars sounds different because of Mars’ unique atmosphere. He spoke with Weekend Edition’s Lulu Garcia-Navarro in March.
The scientists took into account atmospheric pressure, density and chemistry to simulate how the Earth’s sound might change on Mars.
