The sound was received in InSight by both an air pressure sensor and a seismometer. When the air pressure sensor directly sensed the air vibrations, the seismometer recorded the vibrations that the Mars wind blows from the solar panels of InSight. Scientists estimated the wind was between 10 and 15MPH.
Tom Pike, a part of the InSight team of scientists, said, 39 InSight 's workout acts like a giant ear. "The solar panels on the sides of the ship react to the pressure fluctuations of the wind. InSight flaps its ears and seems to hear the Mars wind blowing.
