huffpost – Sounds of Mars: NASA Releases First-Ever Audio From Another Planet

For the first time ever, NASA has recorded audio on another planet – and the beat is pretty solid.

The Perseverance rover contains two microphones, an experimental microphone and a scientist, to record sound as it explores the Jezero Crater for evidence of ancient microscopic life. Last week, the rover picked up the sound of the wind after it landed on Mars.

The space agency released two versions of the recording, both of which were best heard with decent headphones. (If you’re listening through computer speakers, you may need to turn up the volume.) One of these contains filtered rover noise so that all you hear is purely the sound of a breeze on Mars:

The other includes the rover’s mechanical audio to give this breeze an extra vibe:

NASA also released audio from its InSight lander, but those clips were captured as vibrations from a seismometer rather than microphones and were not technically sound. Two other microphones sent to Mars had problems: the Mars Polar Lander mission failed and the Phoenix Lander’s microphones never turned on.

The space agency said the sounds on Mars would be a bit different because of the atmosphere, which would lead to “a quieter, more muffled version of what you’ll hear on Earth” as well as higher heights disappearing. or even disappear.

“Some sounds that we are used to on Earth, like whistles, bells or birdsong, would be almost inaudible on Mars,” the space agency said.

Additionally, NASA has released audio clips of what common Earth sounds would sound like on Mars, which you can check out here. Some sound like muffled versions of Earth sounds. But others, like ocean waves, take on a more ominous tone.

Also on Monday, the space agency released high-quality footage of Perseverance entering the Red Planet and landing on the surface:
