“This set of sounds from the surface of Mars were recorded by the microphone on the side of NASA’s Perseverance Rover on Feb. 20, 2021,” a post from NASA reads. “In the first set, sounds from the rover itself dominate. In the second set, the sound was filtered to make sounds from Mars more audible. You can hear a little wind in the second set.”
You can listen to the two clips of audio via NASA’s post. As you’ll hear, the original audio sounds mostly like a high-pitched buzz with just a touch of wind. NASA cleaned up the original audio to filter out the noise Perseverance is making, which is the high-pitched buzz, and it just sounds like wind blowing by the microphone.
Perseverance successfully landed on Mars last Friday and its mission is to seek signs of habitable conditions for life on Mars and to search for signs of past microbial life as well. It’s not only equipped with a microphone to let NASA and the world know what it sounds like on Mars, but it’s also equipped with a special drill that will collect core sample of rocks and soil on the Red Planet that will eventually be brought back to Earth in a future mission.
