Listen to the wind on Mars for the first time, thanks to the InSight landing module


The audio was picked up by an air pressure sensor and by the seismograph on board the InSight. The air pressure sensor detected the air vibrations directly, while the seismograph recorded the vibrations caused by the Martian wind blowing in the solar panels of InSight. Scientists estimate that the wind blows between 10 and 15 mph.

"The InSight lander acts like a giant ear," said Tom Pike, who is part of InSight's scientific team. "The solar panels on the sides of the probe respond to fluctuations in the pressure of the wind, it's as if InSight is putting its ears and hearing the wind from Mars beating it." When we look at the direction of the probe vibrations coming from the solar panels, expected wind direction at our landing site. "

<p>You can listen to the audio in the video above. NASA recommends using headphones or a subwoofer because the tone is too low. But the video also raises the audio in two octaves to make it easier to hear. Recording of the seismograph is only possible during these early stages of the InSight mission, because once placed on the Martian surface, a dome will protect it from the wind and scientists will actively filter the vibrating noise from the probe. This is because the main purpose of the seismograph is to detect marsquakes or earthquakes on Mars.</p>
<p>It's incredibly cool that we can now "hear" Mars, and more audio will be on the way in the near future. When the rover Mars 2020 arrives on the planet, two onboard microphones will record even more Martian sounds. You can check videos separately from the InSight recordings below.</p>
