A Dutch article about this [1] said:

> According to the Chinese space agency CNSA, the sounds are caused by the interaction of different metal parts.

In the video, they also quote the person leading the Mars programme:

> The sound is made by wheels rotating on the surface of the Mars rover. Basically, the sound of different metal objects bumping into each other.

Hmmm, I've heard plenty of metal things bumping into each other, this sounds more like 0.1 bits/s sloshy MPEG audio.

What I'd like to know is, is this actually how it sounded there, or are we mostly hearing compression artifacts?


It should indeed sound distant and muffled with the composition and temperature of Mar's atmosphere. Saw a neat pseudo-documentary on this not too long ago: https://youtu.be/OeYnV9zp7Dk?t=551


Kind of ridiculous to demonstrate what things sound like while playing eerie random background music over it.


Yeah, I thought it sounded like flanging.


Why would it be compression artifacts when they are also sending hires video signal?

This page has some simulations:

Would you say Dutch news is more objective than American news?


No, it's just the news I happen to follow because I am Dutch, and it contained the info they were asking after.
