Earlier this month, NASA’s Perseverance rover sent over the first audio recordings of the Martian surface, revealing the ghostly sound of Martian wind. Now, NASA has revealed a recording of the rover’s force thru Mars’ Jezero Crater, giving us an conception of the racket Martians would hear in the occasion that they got here across the Perseverance rover for the duration of its dawdle.
In the recording, you would possibly perhaps perhaps presumably clearly hear the Mars rover’s steel wheels banging across rocks and gravel, plus the creaks and squeaks of its mobility machine. There’s furthermore a deplorable, high-pitched buzzing sound, even supposing the Perseverance crew isn’t obvious where that noise is coming from. NASA says that the EDL (entry, descent, and landing) microphone used to be a last-minute addition to the rover and underwent minimal testing, so it’s probably that the mic is correct picking up electromagnetic interference from the Rover due to the execrable shielding.
In the occasion you hear closely to the recording, you would possibly perhaps perhaps presumably hear Martians mumbling “♎︎♏︎⬧︎⧫︎❒︎□︎⍓︎ ♋︎●︎●︎ ♒︎◆︎❍︎♋︎■︎⬧︎” … that’s a joke, even supposing I dare anybody to hear thru the uncut 16-minute recording supplied by NASA. In the occasion you didn’t be conscious it used to be from Mars, you would possibly perhaps perhaps presumably announce that any individual left their phone recording whereas rubbing a fork against a chalkboard.
While it certainly doesn’t sound devour song, the Perseverance rover’s recordings manufacture its mission feel more deepest and elevate questions concerning the future of affirm dawdle. Mars is a true affirm, coated in grime, rocks, and craters that no human has ever considered in individual. But we occupy recordings from the planet’s surface, and our library of recordings will continue to develop as the Mars rover wanders spherical the lonely small planet.
