Perseverance Rover recorded Strange Sound Noises while driving on Mars

On March 17, 2021 NASA published 16 minutes of unfiltered sounds of the Perseverance Mars rover driving on Mars’ surface on Sol 16. There are strange noises from Rover’s suspension and wheels. Some of the noises noise generated by the interaction of the rover’s wheels and suspension with the surface can be heard, along with a high-pitched scratching noise. Perseverance’s engineering team continues to evaluate the source of the scratching noise, which may either be electromagnetic interference from one of the rover’s electronics boxes or interactions between the rover mobility system and the Martian surface. The entry, descent, and landing microphone was not intended for surface operations and had limited testing in this configuration before launch.
