Earlier this month, NASA’s Perseverance rover sent the first audio recordings of the surface of Mars, revealing the ghostly sound of the Martian wind. Now NASA has published a recording of the rover̵
In the recording, you can clearly hear the Mars rover’s metal wheels banging over rocks and gravel, plus the creak and squeak of its mobility system. There’s also a nasty, high-pitched buzzing sound, although the Perseverance team isn’t sure where that sound is coming from. NASA says the entry, descent and landing (EDL) microphone was a last-minute addition to the rover and underwent minimal testing, so it’s possible the microphone is picking up electromagnetic interference from the rover due to improper shielding.
If you listen to the recording carefully, you will hear Martians muttering “♎︎♏︎⬧︎⧫︎❒♎︎♏︎⬧︎⧫︎ □ ︎⍓︎ ♋︎ ● ︎ ● ︎ ♒︎ ◆ ︎❍︎♋︎ ■ ︎⬧︎”… that’s a joke, although I dare anyone who wants to listen to NASA’s uncut 16-minute recording. If you didn’t know it was from Mars, you could swear someone left his phone recording while rubbing a fork against a blackboard.
While it certainly doesn’t sound like music, the recordings of the Perseverance rover give its mission a more personal feel and raise questions about the future of space travel. Mars is a real place, covered with dust, rocks and craters that no human has ever seen in person. Still, we have recordings of the planet’s surface, and our library of recordings will continue to grow as the Mars rover roams the lonely little planet.
