The spacecraft’s seismometer and air pressure sensor picked up vibrations from 10-15 mph (16-24 kph) winds as they blew across Mars’ Elysium Planitia on Dec. 1, 2018.
The seismometer readings are in the range of human hearing, but are nearly all bass and difficult to hear on laptop speakers and mobile devices.
We provide the original audio and a version pitched up by two octaves to make them audible on mobile devices.
Playback is suggested on a sound system with a subwoofer or through headphones. Readings from the air pressure sensor have been sped up by a factor of 100 times to make them audible.
Bruce Banerdt is InSight principal investigator at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. Banerdt said in a statement:
“Capturing this audio was an unplanned treatbut one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves.”
