New NASA lander captures first sounds of Mars wind


NASA's new Martian ship has captured the first voices of the "truly extraterrestrial" Mars wind.

Jet Propulsion Laboratory released the sound clips of foreign winds on Friday.

Low-frequency crabs were collected by the InSight off-road vehicle in their first weeks of Mars.

The wind is estimated to be from 16 km / h to 24 km / h. According to the researchers, these are the first sounds that Mars can be perceived by the human ear.

Don Banfield of Cornell University told reporters, "It reminds me that I was sitting outside on a windy summer afternoon … In a sense, we can tell you how this would be if you were stranded on InSight in Mars."

Scientists involved in the project acknowledge that sound has another world quality.

Thomas Pike, of Imperial College London, said the valor was olduğun quite different from everything we've experienced in the world, and I think it's another way of thinking about how far we can get these signals, Imperial he said.

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

Sounds were recorded by an air pressure sensor that was part of a meteorological station, as well as by a seismometer on the deck of the spacecraft.

Low frequencies are a consequence of fine air density of Mars, and even more so of the seismometer itself – this means detecting underground seismic waves far below the human hearing threshold.

The seismometer will be transported to the surface of Mars in the coming weeks; Until then, the team plans to record more wind noise.

In 1976, the Viking builders of Mars shook the wind-driven spacecraft, but it would be a strain to think about it, said JPL's leading scientist in Pasadena, California, Bruce Banerdt of InSight.

Meanwhile, gerçekten truly extraterrestrial bazı sounds from InSight say Banerdt is & in some ways like the Earth, but on some planet that's really unfamiliar in some ways #.

InSight landed in Mars on November 26th.

"We're all still higher than last week's descent … and are less than two weeks after landing, and there's already an incredible new science," said Lori Glaze, NASA's director of planet science. Said. . "Great, fun."
