?list=PLTiv_XWHnOZpzQKYC6nLf6M9AuBbng_O8For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASAs 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 Perseverances Mastcam-Z imager with audio from a microphone belonging to the rovers SuperCam laser instrument.
The laser zaps rocks from a distance, studying their vapor with a spectrometer to reveal their chemical composition. The instruments microphone records the sounds of those laser strikes, which provide information on the physical properties of the targets, such as their relative hardness. The microphone can also record ambient noise, like the Martian wind.
With Perseverance parked 262 feet (80 meters) from the helicopters takeoff and landing spot, the rover mission wasnt sure if the microphone would pick up any sound of the flight. Even during flight, when the helicopters blades spin at 2,537 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 helicopters hum can be heard faintly above the sound of those winds.

Ps...You will need headphones, buds to hear the humming
