A few days after landing on Mars, the spacecraft InSight was able to transmit to Earth what had never been achieved before: sound of the wind on the surface of the "red planet".
The unpublished audio was released by NASA, which specified that the wind was between 5 and 7 meters per second, northwest to southeast, and was recorded and aired on December 1five days after the arrival of the vessel.
The audio was produced thanks to two extremely faithful sensors, one of pressure and another of earthquakes, which record the vibrations in the base and arm of the InSight. Its sound has been increased by two octaves to make it more audible and it is recommended to use a speaker to listen better.
In a teleconference reproduced on NASA's official website, Bruce Banerdt, a researcher at NASA's Jet Propulsion Laboratory (JPL) at InSIght, said:Recording this audio was an unplanned gift. "
InSight has broadcast several images since its arrival on Mars.
Another mission scientist, Tom Pike, said that "InSight acts like a giant ear."
InSight $ 993 million It reached Mars on Nov. 26, after traveling 480 million miles for seven months at 20,000 km / h, three to four times faster than a rifle bullet.
It is the first time since 2012 that an artifact has landed on the red planet, after NASA's Curiosity vehicle, the only one currently active on the surface of the red planet, did so.
How is InSight on Mars and what will it do?
The probe lasted about two years analyzing the interior of Mars to try to unveil the mysteries of its formation billions of years ago. Knowledge that later would allow to better understand the formation of the Earth, the only rocky planet from which its interior was actually studied.
