NASA’s InSight Lander Records Actual Sounds of Wind on Mars

InSight is the first mission dedicated to studying Red Planet's deep interior.

NASA has been exploring Mars for years, but it was never able to capture the winds blowing on its surface.

Now, for the first time, a lander has heard these spooky sounds on Martian surface and recorded them via sensors. NASA has released audio clips of the alien wind Friday. They are basically low frequency rumbles caused by vibrations from the wind and are blowing at speeds of around 15 mph.

"Capturing this audio was an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. "But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves.”

InSight, the first mission to study the deep interior of Mars, blasted off to the space on May and landed on the planet in November 26. Since arriving at Mars in November, the lander is busy learning more about the planet.The sound of the wind on Mars has been captured by two very sensitive sensors attached to the spacecraft. The air pressure sensor and seismometer on InSight lander recorded the sound of the winds in their own distinctive way.

"The InSight lander acts like a giant ear," said Tom Pike, InSight science team member and sensor designer at Imperial College London. "The solar panels on the lander's sides respond to pressure fluctuations of the wind. It's like InSight is cupping its ears and hearing the Mars wind beating on it. When we looked at the direction of the lander vibrations coming from the solar panels, it matches the expected wind direction at our landing site."

InSight has only one seismomter called SEIS (Seismic Experiment for Interior Structure). In a few weeks, the instrument will be placed on the Martian surface by InSight's robotic arm and will be used to measure seismic waves from marsquakes as they move through the planet.
