Among the many instruments aboard Perseverance are two microphones. Although Mars’ atmosphere is a fraction of what we have on Earth, it’s still enough to transmit sound waves, albeit rather weakly.
According to USA Today, Perseverance has recorded about hours of sound: wind, wheels rolling over Martian gravel, the sounds of the probe’s motors, and so on. But NASA has already come up with an interactive experience that allows us to hear what Earth sounds might sound like on Mars. (Have some headphones handy.)
