How does sound travel on Mars?
Nasa’s Perseverance rover has two microphones installed that will, for the first time ever, help understand the acoustic environment on Mars. SuperCam microphone is mounted on the mast, that moves along with the camera which can record air pressure fluctuations from 20Hz to 12.5 kHz or 50 kHz. The second microphone, the EDLCam (Entry, Descent, and Landing Camera), is fixed to the rover’s body on its port side. This second microphone can record frequencies from 20 Hz to 20 kHz. Here is what the setup looks like.
