NASA shares new audio recordings of the Persevering Mars rover | science and planet

In the video, scientists Nina Lanza and Justin Mackie said they were stunned by the range of sound waves on Mars. This is evident, for example, from the part of the sound in which a helicopter can hear the take-off creativity. The atmosphere on Mars dampens the high frequencies, which is why you often hear low tones on the Red Planet. However, sound waves travel a much greater distance than we originally thought. Our models were wrong,” it seems.

Furthermore, the video also shares the wind noise, laser noise, and driving and rotation noise of the Mars rover. With the latter sounds, Lanza points out that the metallic sound is caused by the metal wheels of perseverance as they ride over the rocky surface of Mars.

The Mars chariot has two microphones. One hung on the side of the rover, while the other was mounted on the mast where other measuring equipment was also installed. According to the scientists, the microphones are “ready copies” that are available to everyone and are not specifically designed for space travel. The video shows that the sounds date back to the spring of 2021.
