For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASA’s Perseverance Mars rover used its SuperCam microphone to listen to the Ingenuity helicopter on April 30, 2021 as it flew on Mars for the fourth time.
 
With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the mission wasn’t sure if the microphone would pick up any sound of the flight. Even during flight when the helicopter’s blades are spinning 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 helicopter’s hum can be heard faintly above the sound of those winds.
 
Scientists made the audio, which is recorded in mono, easier to hear by isolating the 84 hertz helicopter blade sound, reducing the frequencies below 80 hertz and above 90 hertz, and increasing the volume of the remaining signal. Some frequencies were clipped to bring out the helicopter’s hum.

The musicians for NASA Explorers: Apollo took inspiration from science fiction, Apollo audio from the NASA archives and the excitement surrounding NASA’s upcoming human exploration of the Moon with the Artemis program. You can listen to the NASA Explorers: Apollo audio series here:

This set of sounds from the surface of Mars were recorded by the microphone on the side of NASA’s Perseverance Rover on February 20, 2021. In the first set, sounds from the rover itself dominate. In the second set, the sound was filtered to make sounds from Mars more audible. You can hear a little wind in the second set. 
 
This is the first time a Mars rover has been equipped with a microphone. The images in this video were taken by Perseverance's Navigation Cameras, or Navcams, on the same day as the microphone sounds, Feb. 20, 2021.
