Perseverance: discover the very first sound ever recorded on the planet Mars

2021-02-22T21:13:21.780Z


The NASA Perseverance robot, which landed on the Red Planet on February 18, recorded the wind blowing on a microphone with a microphone.


A dull, curious noise… coming from Mars.

The NASA Perseverance robot, which landed on the Red Planet on February 18, recorded with a microphone the first sound coming from the planet Mars.

"It is indeed the sound of the wind which was recorded by a microphone and sent back to us," announced a member of the NASA team, during a much-awaited presentation on February 22, 2021.

Now that you've seen Mars, hear it.

Grab some headphones and listen to the first sounds captured by one of my microphones.

Perseverance, whose landing video aired on February 22, is the first robot with two microphones, capable of recording the sound environment in which it is located.

“One microphone that was attached to the rover did not collect actionable data during the descent, but the other device survived the dynamic descent to the surface and obtained sounds from Jezero Crater on February 20.

About 10 seconds after the start of the 60-second recording, a Martian breeze is audible for a few seconds, as are the mechanical sounds of the rover operating on the surface ”, we can read on the NASA website.

As short as it is, this recording is therefore a true technical feat.

The Insight probe had recorded "sounds" in 2018, but they did not come from a microphone, as reported by the Numerama site.

At the time, this was aggregated data from a seismometer and an air pressure sensor, which were manipulated and worked to recreate sound.

"What we have dreamed of for years"

“So far robots have replicated touch on Mars, cameras have given us sight, robotic arms have provided touch, and mineral sensors have allowed us to taste and smell the planet Mars.

But hearing is the last of the five senses that we have not yet experienced on Mars ”, NASA explained on its site, before the launch of Perseverance.

Several videos and photos have been shared since the robot's landing on the planet Mars.

A “fantastic” feat for the NASA team who oversaw the project.

"This is the first time that we have been able to capture an event such as a landing on Mars," Michael Watkins, director of the Jet Propulsion Laboratory where the rover was built, told a press conference.

"It's really fantastic".

The Best is Yet to Come.

"These images and videos are what we have dreamed of for years," said Allen Chen, who was in charge of the landing for NASA.

These will be used by NASA teams to better understand what happens during such a landing.
