NASA shares first ever recording of Mars wind courtesy of InSight


Those listening on a laptop or their phone might not be able to hear the original sound of the wind blowing across the lander's solar panels because the pitch is so low.

NASA's new Mars lander has captured the first sounds of the "really unworldly" Martian wind. It is just incredible to hear the first ever sounds from Mars.

The noise is of the wind blowing against InSight's solar panels and the resulting vibration of the entire spacecraft.

On December 1, InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 15 miles per hour (16 to 24 kph).

InSight's seismometer and another sensor picked up the noise, and it was not planned.

To get high-quality data from the incredibly sensitive seismometer onboard the lander, the team needs to be able to cancel out all the commotion coming from the Martian surface, looking only at signals coming from inside the planet. But the ICC, located underneath the lander's deck, is demonstrating that Mars is still unpredictable.

These vibrations were detected by an ultra-sensitive seismometer developed in the United Kingdom and an air pressure sensor sitting on the lander's deck. But the video also raises the audio two octaves to make it easier to hear.

These pictures are crucial to InSight's mission-they will help NASA decide where to set up InSight's seismometer and heat-flow probe.

'It's like InSight is cupping its ears'.

"Today we can see the first glimpses of our workspace", says Bruce Banerdt, the mission's principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California, speaking in a press statement.

"Humans are multisensor people, and now we have two of our sensors turned on with this mission", with both audio and visual data streaming back to Earth, Don Banfield, the science lead for the air pressure sensor, said during the news conference. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft's solar panels, which are each 7 feet (2.2 meters) in diameter and stick out from the sides of the lander like a giant pair of ears. One has been included specifically to record the sound of a Martian landing for the first time.
