NASA is releasing 'Sound of Mars' more than 75 million kilometers away



The Mars probe 'Perseverance ' launched in July 2020 succeeded in arriving on Mars in February 2021. And NASA has released the 'Sound of Mars' recorded by Perseverance on SoundCloud, a voice file sharing service.

Below is the first 'Martian sound' recorded 18 hours after Perseverance landed on Mars. I'm a little muffled because the Perseverance mic was housed in the deck, but I can hear a 'go' wind.

And in the recording 12 Mars Sun days after landing, you will hear a 'cracking' laser radiating the perseverance to investigate the location and hardness of the surrounding rocks.

Furthermore, the 16-minute audio recorded 16 minutes after the landing on Mars is like this. The noise generated by the wheels and suspension of the rover is heard along with the high-pitched noise. According to NASA, the engineering team is investigating the cause of the treble noise, but it is probably due to electromagnetic interference from the electronics box or the sound of the wheels rubbing against the ground on Mars.

By the way, the wheel of Perseverance is this.

'I found it really noisy when the wheels of Perseverance were driving over the rocks of Mars,' said Vandi Verma, a senior engineer at NASA's Jet Propulsion Laboratory.

Also, camera and microphone lead engineer Dave Gruel said, 'If you hear this sound from your car, stop and tow it. But what you're listening to and where it was recorded. Given that it's a thing, it makes perfect sense to hear this sound. '
