NASA’s Perseverance Rover Records Mars’ Soundscapes - Martian Playlist Available for Listening!

Have you ever wondered what the Red Planet sounds like?

Thanks to NASA's Perseverance Rover's audio recordings of Mars, scientists reduced a year worth of Mars sounds into a five-hour playlist that you can stream on the space agency's official website!

"Sounds of Mars"

The sounds will transform you into the quiet and erratic environment of the Red planet. These audio recordings have confirmed several theories about how the sounds travel on Mars as well.

Rover's audio recordings were released in 2021. However, none of these sounds were unpleasant to hear since most of them were screeches, possibly because of the electromagnetic interference.

But the newly released sounds have become more pleasant as they provided an analysis of how sound travels on the red planet, published last month.

In a report released by Gizmodo, Baptiste Chide, a planetary scientist from Los Alamos National Laboratory, said in a statement last year that the sounds of Mars seemed like it was coming through a wall since Mars's atmosphere is one percent as dense as the Earth.

However, Chide was surprised to learn that Mars turned out to be so quiet that he thought the microphone recorder was broken, as he stated in a press release by the Acoustical Society of America.

The Martian playlist comes with cool variations. You can listen to "Helicopter Flying on Mars" to feel as if you are flying over the planet. If you want some "Star Wars" action audio experience, you can listen to "Lazer Zaps Rock on Mars", or if you simply want the raw sounds of the planet, you can hit up "First Sounds from Mars."

Sounds Slowly Traveling

It is worth noting that Perseverance landed on Mars back in February 2021, which was equipped with several technologies to discover if the planet has ever had a microbial life in its ancient life.

Along with these instruments, it also had two microphones made from an off-the-shelf component that would record the first audio data on the Red Planet. One of the microphones was fastened on the spacecraft's frame and sat above one of its wheels.

The microphone was protected in mesh to keep it from Martian dust, while the second microphone is attached to the rover's SuperCam - one of the spacecraft's main cameras found on its arm above the frame.

Do not be fooled by Mar's redness because it is colder than Earth with its thinner atmosphere. NASA theorized that sound travels slower on Mars, and the recording proved this. They found out that higher-frequency sounds traveled faster compared to lower-frequency noise.

During the planet's winter, carbon dioxide in its polar regions freezes and causes loud sounds, according to NASA. Perhaps, in the future, we could listen to more variations of the Martian playlist and fully revel in the soundscapes of Mars.
