NASA's Mars Perseverance rover beams back first sounds ever recorded on another planet By Sophie Lewis NASA rover sends video and audio from Mars NASA's Perseverance rover, which landed on Mars less than one week ago, has beamed back the first-ever audio recordings from the surface of the red planet. NASA released the audio clips Monday, along with never-before-seen video footage of the rover landing last Thursday, and the most sophisticated images yet taken of Mars. Along with 25 onboard cameras, the rover also carries two microphones. One failed to work during the rover's descent, but the other captured the sounds of the Martian wind blowing past, as well as the whirring noise of the rover itself.
