InSight ships landed on the Martian surface, using seismographs and air pressure sensors to capture the wind blowing.
NASA Jet Propulsion Laboratory (JPL) announced the wind sound on Mars captured by InSight , Guardian reported on December 7. Low-frequency noises are recorded by InSight during the first week of operation on the red planet. The wind speed is then estimated at 16-24km / h.
The sound on Mars is caused by the seismic and the air pressure sensor is collected.
This is the first sound from Mars that humans hear. " This sound is an interesting thing outside the plan. But part of our mission is to measure the movements on Mars and, of course, it also includes the movement caused by sound waves , " Bruce Banerdt , principal researcher of the InSight project at JPL, said.
This sounds reminiscent of a windy summer afternoon, according to Don Banfield, an expert at Cornell University."This is partly what you hear if you sit on the InSight train in Mars," Banfield said. Meanwhile, researcher Thomas Pike of the Royal College of London commented, this sound is different from anything that has ever heard on Earth.
In the video published by the JPL, the noise came from the Martian wind blowing into InSight's solar panels and shaking the ship. InSight's air pressure sensor and seismograph have obtained this sound. It has a low frequency because of the atmosphere on Mars, mainly composed of CO 2 , very dilute. The second reason is the seismic operation, the capital device used to measure seismic waves below the threshold of human hearing.
The noise was caused by the Martian wind blowing into InSight's solar panels and shaking the ship.
InSight ship landed on the surface of Mars on November 26."We are still excited about the landing event and less than two weeks later, we get amazing scientific data. It's great," said Lori Glaze, a NASA expert.
