Rover microphones reveal secrets of the Red Planet.
Space exploration takes on a new dimension thanks to the use of microphones on board NASA's Perseverance rover. These sensors successfully detect wind gusts and even record the sounds of laser pulses from the rover's instruments. In addition, microphones recorded the sound of the rotating blades of the Mars Ingenuity helicopter and the rhythm of the MOXIE oxygen production experiment on board Perseverance.
Timothy Leighton, a professor at the University of Southampton, actively supports the idea of including acoustic sensors in research vehicles for Mars and other space destinations. "It's not just about listening to sounds," says Layton. By analyzing recorded sounds, you can get information about wind, temperature, chemical composition, and turbulence on Mars.
Leighton developed an acoustic simulator for the planetarium, which reproduces the expected sounds of various phenomena-thunder, wind and cryovolcanoes, which are found on Venus, Mars and Saturn's largest moon, Titan.
Since its landing in February 2021, NASA's Perseverance rover has become the first spacecraft on the Red Planet capable of transmitting acoustic data from the surface. The main sources of recorded sounds on Mars include the atmosphere (wind and turbulence), shock waves from instruments on board the Rover, and artificial sounds such as the rover's engines and the rotating blades of the Ingenuity helicopter.
There is already a whole "Perseverance Playlist" that includes hours of Martian sounds. Researchers note that the brightest sounds are made by flights of the Ingenuity helicopter.
Thus, it turns out that outer space can serve as a valuable source of audio recordings.
