The Martian atmosphere interacts with the surface, redistributing dust and sand particles (Kahre et al., 2017). Small particles are lifted by convective vortices and by strong wind gusts, and are subsequently transported before settling again (

The "Mars Microphone" is one of the five measurement techniques of SuperCam, an improved version of the ChemCam instrument that has been functioning aboard the Curiosity rover for several years. SuperCam is located on the rover's Mast Unit, to take advantage of the unique pointing capabilities of the rover's head. In addition to being the first instrument to record sounds on Mars, the SuperCam Microphone can address several original scientific objectives: the study of sound associated with laser impacts on Martian rocks to better understand their mechanical properties, the improvement of our knowledge of atmospheric phenomena at the surface of Mars such as atmospheric turbulence, convective vortices, dust lifting processes and wind interactions with the rover itself. The microphone also helps our understanding of the sound signature of the different movements of the rover: operations of the robotic arm and the mast, driving on the rough surface of Mars, monitoring of the pumps, etc. The SuperCam Microphone was delivered to the SuperCam team in early 2019 and integrated at the Jet Propulsion Laboratory (JPL), Pasadena, CA with the complete Su-perCam instrument. The Mars 2020 Mission launched in July 2020 and landed on Mars on February 18, 2021. The mission operations are expected to last until at least August 2023. The microphone is operating perfectly.

Wind-induced noise is observed by the SuperCam Mars microphone on Perseverance.• Microphone and air temperature data are used to estimate the wind speed at high frequencies, using a machine learning model.• The wind speed estimate is used to examine the relationships between turbulent intensity, pressure drops, temperature and energy flux.
