NASA's new ribbon captures the first sounds of the wind on Mars

NASA's Mars Mars March march, Cape Cavaveral, FL.A. won the first sounds of the "really vague" wind on Mars.

The motor-powered laboratory released audio clips from foreign winds on Friday. Low frequencies were collected by InSight pilots during the first week of Mars operations.

The wind is estimated to blow at 16 km / h to 24 km / h. These are the first sounds from Mars, discovered by human ears, according to researchers.

"It reminds me of sitting in the windy afternoon … In a sense, it would sound like if you were sitting on Mars at InSight," said Dan Banfield of Cornell University for reporters.

The scientists involved in the project agree that sound has some sort of world-class quality.

Thomas Pike of Royal College London said the rumbling was "quite different from what we experienced on Earth, and I think it only gives us another way of thinking about how far we get these signals."

Mars Sounds: NASA's heir to Mars wind

The noise is from the wind falling against the InSight's solar panels and as a result of the vibrations of entire spacecraft. The sounds were recorded with a pressure sensor inside the ice sheet that is part of the meteorological station, as well as the seismometer on the deck of the spacecraft.

Low frequencies are the result of the density of Mars's air density and even of the seismometer-it is meant to detect underground seismic waves, well below the threshold of human hearing. The threshold will move to the surface of Mars in the coming weeks; by then, the team plans to record more noise from the wind.

In 1976, the Marquise of the Vikings on Mars was trembling by spacecraft spacecraft, but it would be a good idea to consider how it sounds, said InSight, Bruce Banner, of JPL in Pasadena, California.

"Usually aliens" sounds from InSight, meanwhile, have pictures of Banerdt he "is on a planet that is somehow like Earth, but in a way really alien."

InSight landed on Mars on November 26.

"We are all still at a high level since the landing last week … and here we are less than two weeks after the landing, and we have already received an incredible new science," said Lori Glases, acting director of NASA's planetary science. "It's cool, it's fun."
