Earlier this month, NASA’s Perseverance rover despatched over the first audio recordings of the Martian floor, revealing the ghostly sound of Martian wind. Now, NASA has printed a recording of the rover’s drive by Mars’ Jezero Crater, giving us an concept of the racket Martians would hear in the event that they got here throughout the Perseverance rover throughout its journey.
Within the recording, you may clearly hear the Mars rover’s steel wheels banging throughout rocks and gravel, plus the creaks and squeaks of its mobility system. There’s additionally a nasty, high-pitched buzzing sound, although the Perseverance workforce isn’t certain the place that noise is coming from. NASA says that the EDL (entry, descent, and touchdown) microphone was a last-minute addition to the rover and underwent minimal testing, so it’s attainable that the mic is simply choosing up electromagnetic interference from the Rover resulting from improper shielding.
If you happen to pay attention intently to the recording, you may hear Martians mumbling “♎︎♏︎⬧︎⧫︎❒︎□︎⍓︎ ♋︎●︎●︎ ♒︎◆︎❍︎♋︎■︎⬧︎” … that’s a joke, although I dare anybody to pay attention by the uncut 16-minute recording offered by NASA. If you happen to didn’t understand it was from Mars, you might swear that somebody left their cellphone recording whereas rubbing a fork towards a chalkboard.
Whereas it actually doesn’t sound like music, the Perseverance rover’s recordings make its mission really feel extra private and lift questions on the way forward for area journey. Mars is an actual place, lined in mud, rocks, and craters that no human has ever seen in individual. But we’ve got recordings from the planet’s floor, and our library of recordings will proceed to develop because the Mars rover wanders across the lonely little planet.
