News – Listen to something that no one has heard before: the winds on Mars!



FROM THIS WORLD | What's happening in space – the biggest news that comes to Earth from space

Friday, 7 December 2018, 17:19 – Want to listen to something amazing? Be one of the first people who've ever heard the winds on Mars thanks to NASA's new InSight landing!

It was less than two weeks since InSight touched the surface of the Red Planet, but already sent amazing things to wonder about.

Of course, the images you've already uploaded are great! They demonstrate the clear details of the airplane, its components and its surroundings, and these are just the beginning!


NASA InSight broke this raw photo using the handheld-mounted camera.

The latest edition of the InSight team is really the first! The first time people heard the sounds of the winds on Mars!

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

This rustling noise was the vibrations caused by the wind flowing through the InSight solar panels that were recorded by the sensible landing seismometer. Below is recorded by the InSight meteorological station – specifically the low-frequency infrasound recorded by the atmospheric pressure sensor.

The vibrations have been shifted to the sound range of people and accelerated so we can understand them, but it really sounds like sitting on the deck of the tendon and hearing your ears playing your ears!

We saw the surface of Mars through the pictures. We've even touched pieces from Mars, because we've found Martian meteorites here on Earth. We studied the atmosphere of Mars with terrestrial routers and satellites.

Never before have we been able to hear the sounds of the wind on Mars. Eh!

"Capturing this audio is an unplanned treatment," said InSight chief researcher Bruce Banner, according to NASA. "But one of the things our mission is dedicated to is measuring the motion of Mars, and naturally this involves movement caused by sound waves."

According to NASA,

Two very sensitive sensors of the spacecraft found these wind vibrations: a horn sensor and a seismometer sitting on the deck of a landing ship waiting to be deployed by InSight's robotic arm. Both instruments record wind noise in different ways. The Air Pressure Sensor, part of the APSS, which collects meteorological data, records these vibrations directly. The earthquake detects earth vibrations caused by the wind, moving over the solar panels of the spacecraft, each half a meter (2.2 meters) in diameter, and going to the side of the rack like a giant pair of ears.

This is the only mission phase, during which the seismometer, called seismic internal structure experiment (SEIS), will be able to detect vibrations generated directly from the land. In a few weeks, it will be placed on the surface of Mars by the robotic arm of InSight, and then covered with a dome shield to protect itself from wind and temperature changes. This will still detect the movement of the earth, though channeled through the surface of Mars. Currently, he records vibration data that later scientists will be able to use to remove ground noise when SEIS is on the surface, allowing them to find better mining carcasses.

Continue to watch to come more than InSight!
