The Mars Perseverance rover records the first audio of a dust storm

Perseverance has captured the sound of dust grains impacting NASA’s rover, and the recording could be key to understanding how dust is transported around Mars.

The recording comes from a microphone in the perseverance vehicleThe ‘s SuperCam instrument on September 27, 2021, during the rover’s mission Sol 215. (A sun is a Martian day and about 40 minutes more than a day on Earth). Other instruments also detected the dust storm, which appears in images from Perseverance’s NavCam and in temperature and pressure measurements from Perseverance’s Mars Environmental Dynamics Analyzer (MEDA). Additionally, the scientists were able to use the microphone to accurately measure wind speed based on the sound intensity of the gusts.
