InSight science team member Tom Pike says the lander acts like a giant ear as the solar panels respond to the wind.
New audio has been released from the surface of Mars, and the sound is more hauntingly familiar than you might expect. The air pressure sensor recorded the vibrations directly from changes in the air. That wind pattern is consistent with the direction of dust devil tracks that were observed in the landing area from orbit, NASA said.
The sound of wind is easily recognizable to most people on Earth but for the first time the sound of wind on Mars has been released.
In the video posted on Twitter, NASA said mission engineers will eventually move the seismometer off the lander and onto the ground.
The craft's landing comes as part of NASA's mission to explore the planet's deep interior. The air pressure sensor, which will collect meteorological data, recorded these air vibrations directly.
The Instrument Deployment Camera (IDC), located on the robotic arm of NASA's InSight lander, took this image of the Martian surface the day the spacecraft touched down on the Red Planet, and was relayed from InSight to Earth via NASA's Odyssey spacecraft, now orbiting Mars, on November 26, 2018.
The audio was captured by two different pieces of state of the art, hyper sensitive recording equipment aboard the lander.
'The solar panels on the lander's sides are ideal acoustic receivers, ' Prof Pike said.
To get the first data from the seismometer instrument package has been fantastic and even with a short test run the analysis is now full swing.
The reason for having a seismometer on the lander is to see if earthquakes (which on Mars are called Marsquakes) behave in the same way as they do on earth. These are the first sounds from Mars that are detectable by human ears, according to the researchers. And NASA will be putting two microphones on the rover it's planning to send to Mars in 2020.
"Capturing this audio was an unplanned treat", said Bruce Banerdt, the InSight principal investigator at Nasa's lab in Pasadena, California. The air sensor recorded air vibrations, while the seismometer recorded the lander's vibrations from the wind blowing across its large solar panels.
NASA's new tool - the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport - aka "InSight" touched down on Mars on November 26.
