We know what Mars looks like, but there's a lot of mystery around what Mars sounds like. NASA Administrator, Jim Bridenstine, shared a video about the new audio to Twitter Friday.

Listen to Martian wind blow across NASA's InSight lander.

This latest collection of images from the spacecraft's landing site at Elysium Planitia comprises 17 novel snapshots and was received by mission controllers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, on December 4 - or sol 8 of the InSight Mars mission.

InSight isn't exactly a recording studio on Mars, but an air pressure sensor inside the lander and a seismometer on the lander's deck were both able to pick up wind vibrations. The wind was estimated to be blowing 10 to 15 miles per hour from northwest to southeast, which matched the direction of dust devil streaks observed from another NASA spacecraft in orbit.

NASA increased the pitch of the audio by two octaves for those who couldn't hear the original, and for those listening on a laptop or a phone.

"Capturing this audio was an unplanned treat", InSight principal investigator Bruce Banerdt said.

InSight science team member Tom Pike says the lander acts like a giant ear as the solar panels respond to the wind. "It's like InSight is cupping its ears and hearing the Mars wind beating on it", he said. Readings from the air pressure sensor have been sped up by a factor of 100 times to make them audible.
