The new NASA landing system captures the first sound of the Martian wind



NASA's new Mars Lander captured the first sounds of the "really unwanted" Martian wind.

The Jet Propulsion Laboratory released on Friday sound clips of strange wind.

Low frequency rumblings were collected by the InSight landing station during the first week of operation on Mars.

It is estimated that the wind blows 16 km / h to 24 km / h. These are the first sounds from Mars, which researchers say revealed by human ears.

"It reminds me that I was sitting outside on the windy summer afternoon … In a sense, it sounds like you're sitting at InSight landing on Mars," Don Banfield told Cornell University reporters.

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

Thomas Pike of the Imperial College in London said that knocking is "quite different from what we have experienced on Earth, and I think it only gives us another way to think about how far we have received these signals."

Noise is caused by wind blazing against the InSight solar panel and the resulting vibrations of the entire spacecraft.

The sounds were recorded by the air pressure sensor inside the landing unit that is part of the meteorological station as well as the seismometer on board the spacecraft.

Low frequencies are the result of the thin air density of Mars and even the seismometer itself – it is designed to detect underground seismic waves, well below human hearing.

The seismometer will be relocated to Mars in the coming weeks; until then, the team plans to record greater wind noise.

Viking landers on Mars in 1976 lifted spacecraft that shook the wind, but it would not be right, said InSight lead scientist Bruce Banerdt of the JPL in Pasadena, California.

While InSight sounds "really unscrupulous" sounds, Banerdt shows it to be "on a planet that is in some ways Earth-like, but in some ways really alien."

InSight landed on March 26 on Mars.

"We are still in the same place last week … and here we are less than two weeks after landing and we have some amazing new science," said Lori Glaze, NASA's Planetary Science Executive Director. "It's fine, it's fun."
