If you want to hear what Mars has to say, you’re going to have to listen closely. Very closely. It’s not that there isn’t any sound on Mars. Of course there is. Martian ambiance – recorded on microphones attached to NASA’s Perseverance rover – is largely dominated by the gentle clipping of the mic as … Continue reading 'According to Perseverance, Mars is Quiet… too Quiet'
If you want to hear what Mars has to say, you’re going to have to listen closely. Very closely.
The soundscape of Jezero crater, where the rover made its landing last February, is further punctuated by the mechanical groans of Perseverance itself, the crackle of its ‘SuperCam’ laser instrument, and exhales of gas as the rover blows dust away from outcrops of rock for closer study. Perseverance even recorded the whirring rotors of its small companion robot, Ingenuity, a tiny helicopter being used to scout terrain ahead of the rover’s path.
But even with all this activity, Mars is unsettlingly quiet. “At some point, we thought the microphone was broken, it was so quiet,” says Sylvestre Maurice, an astrophysicist at the University of Toulouse who is studying the behavior of soundwaves in Mars’ atmosphere. The speed of sound is not a universal constant. It changes depending on the medium through which the sound is passing.low-pitched sounds travel at about 537 mph , while higher-pitched sounds move at 559 mph .Not only does sound move more slowly on Mars, but it doesn’t travel as far either, dissipating extraordinarily quickly. A sound that travels 65 meters on Earth might only go 8 meters on Mars, and a high-pitched sound wouldn’t even make it that far.
