Microphones and pressure sensors are emerging as valuable tools for planetary exploration. NASA’s InSight mission enabled long term first infrasound measurements on Mars, while Perseverance rover’s SuperCam microphone captured the first direct acoustic recordings from the Martian surface. These instruments provide new insights into atmospheric dynamics, including wind patterns, turbulence, and surface-atmosphere interactions. ESA’s ExoMars PACIS payload, which includes a microphone, barometer, and temperature sensor, is designed to monitor acoustic and pressure signals during Entry, Descent, and Landing. Such data enhance our understanding of both the atmospheric environment and dynamic surface processes like impacts and particle transport. Acoustic measurements also open promising avenues for studying solid planet processes, particularly on Venus, where direct seismic instrumentation is not currently feasible. Detecting quakes or volcanic activity via atmospheric pressure waves recorded from aerial platforms may offer a novel method for probing planetary interiors remotely.
