Sounds of Mars

The Perseverance rover carries two microphones, letting us directly record the sounds of Mars for the very first time. One, an experimental mic, may capture the landing itself. The other mic is for science. Both mics may even capture the sounds the rover makes.

Even though Earth and Mars are entirely different planets, it may be comforting to know that if you were on Mars, you might still sound pretty much like yourself. 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. On Mars, the atmosphere is entirely different. But, the biggest change to audio would be to high-pitch sounds, higher than most voices. Some sounds that we’re used to on Earth, like whistles, bells or bird songs, would almost be inaudible on Mars.
