News – Don't hear anything people have never heard before: the winds of Mars!

7 December 2018, Friday 17:19 – You want to hear something amazing? Become one of the first to hear the winds in Mars, thanks to NASA's new InSight lander!

Less than two weeks have passed since InSight touched the surface of the Red Planet, but we're sending amazing things for us.

Of course, the images it quotes are great! They showed the land, its components and its surroundings clearly, and they were just the beginning!

NASA InSight breaks up this raw photo using the sleeve-mounted device distribution camera. 2.2 m wide solar panel, 2.2 m wide solar panel, two TWINS temperature and wind sensor (center left), UHF antenna (bottom center), SEIS seimometer (bottom left) and white dome (center left) now cover the pressure sensor .

The latest version of the InSight team is truly a first! It's the first time people hear the noise in Mars!

The clip is only 20 seconds, but it's worth it! Listen below!

This noisy noise was caused by the wind flowing on the solar panels of InSight, which was recorded by the ship's sensitive seismometer. The weather station of InSight was recorded below – especially the low frequency infrared detected by the atmospheric pressure sensor.

The vibrations have slipped into the audible range of people and accelerated so that we can make sense of them, but it feels as if the deck is sitting on the deck of the ship to hear the whistling under your ears!

We saw the surface of Mars with pictures. We've even touched on Mars, because we found the Martian meteors here on Earth. We studied the atmosphere of Mars from land, rovers and satellites.

Nevertheless, we have never heard wind sounds on Mars. Wow!

According to NASA, "The capture of this voice was an unplanned treat," says InSight chief researcher Bruce Banerdt. "But one of the things that our mission is dedicated to is to measure the movement in Mars and, naturally, the movement caused by sound waves."

According to NASA:

The two very sensitive sensors on the spaceship detected these wind vibrations: a seismometer on the ship's deck, waiting to be deployed by an air pressure sensor inside the driver and the robotic arm of InSight. The two instruments recorded wind noise in different ways. The air pressure sensor, which is part of the Auxiliary Load Load Sensor Subsystem (APSS), which collects meteorological data, records these air vibrations directly. The seismometer recorded wind vibrations, each 7 feet (2.2 meters) in diameter caused by the wind moving on the solar panels of the spacecraft, and dangling outwards from the side of the landing side like a gigantic pair of ears.

This is the only phase of the mission, where the seismometer, called the Inner Structure Seismic Test (SEIS), can detect the vibrations generated by the land directly. Within a few weeks, the robotic arm of InSight will be placed on the surface of Mars, then covered with a domed shield to protect it from wind and temperature changes. Although Mars is channeled to the surface, it will still detect ground motion. For now, it is now possible to record the vibrational data that scientists can use to cancel noise from the ground while SEIS is on the surface, allowing them to identify better real marches.

Stay tuned for more from InSight!
