What was it supposed to be,wind noise?

Am I the only one that didn't think Mars has an atmosphere?

Mars' Atmosphere: Composition, Climate & Weather
https://www.space.com/16903-mars-atmosphere-climate-weather.html

The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. Here's a breakdown of its composition, according to a NASA fact sheet:

Carbon dioxide: 95.32 percent
Nitrogen: 2.7 percent
Argon: 1.6 percent
Oxygen: 0.13 percent
Carbon monoxide: 0.08 percent
Also, minor amounts of: water, nitrogen oxide, neon, hydrogen-deuterium-oxygen, krypton and xenon

"Carbon dioxide: 95.32 percent"

Egads!
It looks like "climate change" has already come and gone there...

@thackney

Yeah,but is carbon dioxide thick/heavy enough to create wind noise?I remember at least one report claiming it was wind blowing,but without something thick enough/heavy enough to create an atmosphere,how can there be wind noise?

Marvin the Martian gas?

Yes.

@thackney

Thanks! I had no idea of it's weight/mass compared to that of oxygen.
