New NASA probe captures the first sounds of the Martian wind



NASA's new space probe captured the first sounds of the "really non-mundane" Martian wind.

The Jet Propulsion Laboratory has released audio clips of the alien wind on Friday.

Low-frequency rumors were collected by the InSight module during its first week of operations on Mars.

It is estimated that the wind blows between 16 and 24 km / h. These are the first sounds of Mars that are detectable by human ears, according to the researchers.

"It reminds me of sitting on a windy summer afternoon … In a way, it's like you're sitting in the InSight landing module on Mars," Don Banfield of Cornell University told reporters.

Scientists involved in the project agree that sound has a supernatural quality.

Thomas Pike of Imperial College London said the crash is "quite different from anything we have experienced on Earth, and I think that gives us another way of thinking about how far we are getting those signals."

The noise is of the wind blowing against InSight's solar panels and the resulting vibration of the entire spacecraft.

The sounds were recorded by an air pressure sensor inside the probe that is part of a weather station as well as by the seismograph on the spacecraft deck.

Low frequencies are the result of the rarefied air density of Mars and, even more so, of the seismograph itself – it serves to detect underground seismic waves well below the threshold of human hearing.

The seismograph will be moved to the Martian surface in the next few weeks; until then, the team plans to record more wind noises.

The 1976 Viking landers on Mars picked up the quake of the spacecraft caused by the wind, but it would be overkill to consider it solid, said Bruce Banerdt, chief scientist at JPL's InSight in Pasadena, Calif.

InSight's "really non-mundane" sounds, meanwhile, have Banerdt's image that he "is on a planet that is, in a way, Earthlike, but in a way really alien."

InSight landed on Mars on November 26.

"We've all been on the rise since landing last week … and here we are less than two weeks after landing, and we already have incredible new science," said Lori Glaze, interim director of planetary science at NASA. . "It's cool, it's fun."
