NASA\u2019s Perseverance Mars rover used one of its two microphones to listen as the Ingenuity helicopter flew for the fourth time on April 30, 2021. A new video combines footage of the solar-powered helicopter taken by Perseverance\u2019s Mastcam-Z imager with audio from a microphone belonging to the rover\u2019s SuperCam laser instrument.<\/p>\n<p>The laser zaps rocks from a distance, studying their vapor with a spectrometer to reveal their chemical composition. The instrument\u2019s <a href=\"https:\/\/phys.org\/tags\/microphone\/\" rel=\"tag\" class=\"\">microphone<\/a> records the sounds of those laser strikes, which provide information on the physical properties of the targets, such as their relative hardness.

Even during flight, when the helicopter\u2019s blades spin at 2537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter\u2019s hum can be heard faintly above the sound of those winds.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft.
