Perseverance Rover, Joe landed on mars In February this year, it is equipped with two microphones, which have already provided about five hours of recording of various sounds, such as wind and sound during displacement on the planet’s surface, for example. The recordings are important for scientists to understand the Red Planet in new ways – and, of course, NASA Invites the audience to hear the sound of Mars.
Baptiste Chaide, a planetary scientist who studied the data collected by microphones, describes that these sounds make the listener feel as if they are on the planet. “Martian sounds have strong bass vibrations, so when you put on the headphones, you can really feel them; I think the microphone will be an important tool for the future of Mars and the science of the Solar System.”

Perseverance is the first robotic vehicle sent to Mars equipped with two microphones – one on the side of the rover and the other on the mast, to complement the rock and atmosphere analysis carried out by the Supercam instrument. To do this, the instrument makes laser shots at rocks and the ground and then studies the resulting dust with a camera. Since this process occurs hundreds of times per target, there are great opportunities for the rover’s microphones, which have already captured the sound of more than 25,000 fires.
As sound travels through the air, some recordings have helped scientists learn more about changes in the planet’s atmosphere — and SuperCam’s microphone is great for that, as it is on the rover’s mast. and is thus able to monitor the “micro turbulence” caused by the minimum. change in air. This information complements that obtained by dedicated sensors of the Mars Environmental Dynamics Analyzer (MEDA) instrument.
The microphone also allows the study of how sound is transmitted across the planet. Since the Martian atmosphere is less dense than Earth’s, scientists already expected high-pitched sounds would be particularly difficult to hear – so much so that recordings of sound Fourth flight of Ingenuity Helicopter was a welcome surprise, allowing the researchers to conclude two of three different models designed to demonstrate the propagation of sound on Mars.
