Listen to the wind on Mars for the first time thanks to InSight lander

The audio was received by the atmospheric pressure sensor and the seismometer on the InSight board. The air pressure sensor directly detects airborne vibrations while the seismometer detects vibrations caused by the wind on Mars, blowing through InSight's solar panels. Scientists estimate that the wind blows between 10 and 15MPH.

"The InSight Inspector acts as a huge ear," says Tom Pike, part of InSight's research team. "Reactor solar panels respond to fluctuations in wind pressure, as InSight clings to their ears and hears that the wind on Mars is on it." When we look at the direction of the earth vibrations coming from the solar panels, the expected direction of the wind in our landing. "

<p>You can hear the sound in the video above. NASA recommends using a headset or subwoofer because the terrain is pretty low. But the video also boosts the audio with two octaves to make it easier to listen. Seismometer recording is possible only during these early stages of the InSight mission, as once it is placed on the surface of Mars, a dome will protect it from the wind, and scientists will actively filter the vibrational noise originating from the land. This is because the main purpose of the seismometer is to find marshes or earthquakes on Mars.</p>
<p>It's incredibly cool that we can now "hear" Mars, and in the near future there will be more audio. When the Mars 2020 engine lands on the planet, two microphones on board will record even more Martian sounds. You can view individual videos from the InSight recordings below.</p>
