NASA’s Perseverance Rover Captures Puff, Whir, Zap Sounds from Mars

Listen closely to new sounds from Mars recorded by NASA’s Perseverance Mars rover, including puffs and pings from a rover tool, light Martian wind, the whirring of the agency's Ingenuity Mars Helicopter, and laser zaps. Most of the sounds – best heard through headphones with the sound up – were recorded using the microphone belonging to Perseverance’s SuperCam instrument, mounted on the head of the rover’s mast. Other sounds, including the puffs and pings from the rover’s Gaseous Dust Removal Tool, or gDRT, blowing shavings off rock faces, were recorded by another microphone mounted on the chassis of the rover. A new study based on recordings made by the rover reveals that the speed of sound is slower on the Red Planet than on Earth and that, mostly, a deep silence prevails in the much thinner atmosphere.
