NASA’s InSight lander ‘hears’ Martian wind

Adjust Comment Print

InSight lander's sensors are created to detect quakes and air pressure through wind vibrations.

"In some sense, this is what it would sound like if you were sitting on the Insight lander on Mars". While the air pressure sensor recorded the air vibrations directly, the seismometer captured the 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.

In the video posted on Twitter, NASA said mission engineers will eventually move the seismometer off the lander and onto the ground.

What does Mars sound like? It will explore the planet's deep interior and analyze seismic activity or "marsquakes".

A second version of the audio was also released with the audio pitched slightly higher, where the sound is more perceivable to the human ear.

The raids came a day after Italian police arrested Settimo Mineo, the new head of Sicily's Cosa Nostra mafia. In Germany, federal police said there had been multiple arrests in the early morning raids.

The audio was captured by two different pieces of state of the art, hyper sensitive recording equipment aboard the lander.

"The InSight lander acts like a giant ear", said Tom Pike, InSight science team member and sensor designer at Imperial College, London.

Sort of. The probe's instruments detected vibrations of the Martian air over its solar panels in frequency that human ears can hear.

With the lander, NASA hopes to study the "vital signs" of Earth's neighboring planet, including its "pulse" (seismology), "temperature" (heat flow), and "reflexes" (precision tracking).

More images from InSight's arm were scheduled to come down this past weekend. The raw images the craft sends back to NASA are hosted on the InSight mission site where anyone can take a look at them all and see what the craft's instruments see while on Mars. The low-frequency rumblings were collected by the InSight lander during its first week of operations at Mars.
