NASA releases audio recordings of first wind sounds, laser strikes captured on Mars


NASA’s Jet Propulsion Laboratory (JPL) launched two historic audio recordings from the floor of Mars on Wednesday.

Within the first audio clip, recorded utilizing the Perseverance Mars rover’s two microphones, listeners can hear wind.

Of their publish on SoundCloud, NASA described the sound as “listening to a seashell or having a hand cupped over the ear.” 

They obtained the audio from the instrument on Feb. 19, round 18 hours after touchdown on the planet’s Jezero Crater.

“The rover’s mast, holding the microphone, was nonetheless stowed on Perseverance’s deck, and so the sound is muffled,” they defined. 

Within the second clip, listeners can hear laser impacts on a rock goal in audio that was taken on March 2. 

“The sounds of 30 impacts are heard, some barely louder than others. Variations within the depth of the zapping sounds will present data on the bodily construction of the targets, similar to its relative hardness or the presence of weathering coatings,” NASA wrote in a caption. “The goal, Máaz (‘Mars’ in Navajo), was about 10 toes (3.1 m) away.”

Each recordings had been taken utilizing the rover’s SuperCam, which is a rock-vaporizing instrument mounted on the “head” of the rover’s mast that may assist scientists hunt for fossils on the purple planet.

Within the clip with audible wind, the mast on which the microphone sits was nonetheless stowed, muffling the sound, which Institut Supérieur de l’Aéronautique et de l’Espace (ISAE-SUPERAO) researcher and planetary scientist Naomi Murdoch mentioned throughout a joint information convention with Centre Nationwide D’Etudes Spatiales (CNES) and NASA on Wednesday.

“To begin with, on the floor of Mars, we’ve got a really low atmospheric strain. It is really 150 instances decrease than on Earth. As well as, the environment is made up of carbon dioxide,” Murdoch defined. “And, these two components collectively imply that sound would not propagate in the identical approach on the floor of Mars because it does on Earth.”

“For that purpose, the SuperCam microphone is especially delicate. And this permits us to report sounds regardless of the robust attenuation within the Martian environment,” she mentioned.

The Mars 2020 rover marks the third time the microphone was despatched to Mars.
