InSight probe captured sound of Mars winds

  • Listen to the sky NASA reveals the sound of wind on Mars

A spacecraft that touched down on Mars ten days ago to conduct experiments and measure "marsquakes" has recorded the first ever sounds of Martian winds.

NASA estimates the winds were blowing slowly at around "5 to 7 meters a second" from the northwest to the southeast of the surface of the planet on December 1.

Less than two weeks have passed since InSight touched down on the Surface of the Red Planet and we're already receiving unbelievable data that we can contemplate.

To "hear" the low frequency rumble of the Martian wind on the lander being picked up by the SEIS-SP is really eerie and provides a strangely human connection to this very different environment.

This is the only time when vibrations from the lander will be recorded by the seismometer, since it will be moved by the craft's robotic armed and placed on the Martian surface, along with other instruments.

The wind sound can be heard on the video above.

Nasa said that the air pressure sensor used to collect meteorological data recorded these air vibrations directly. It's like InSight is cupping its ears and hearing the Mars wind beating on it.

Windy, if NASA's InSight Lander is to be believed.

Earlier it was reported that the InSight probe made a successful landing on Mars at the end of November 2019.

An external seismometer which will be deployed by InSight's robotic arm, took in the vibrations caused by wind blowing over InSight's solar panels. Because most people won't readily have access to these items, NASA also has included a higher frequency version of the clip that makes it audible when played on a laptop or smartphone's speakers.

The latest release from the InSight team is truly a first of its kind.

The photo is one of many that came back from Mars this week showing the planet and the craft itself.

An upcoming mission, the Mars 2020 rover, will have two microphones on board for clearer sound recording.
