None of us will probably ever make it to the red planet but if you want to get a feel for what Mars would sound like (or hear what it’s like from inside an airlock), saddle up with this video from Cody’s Lab.
He drops a camera inside a vacuum chamber and then turns down the pressure to mimic what it’s like on Mars. He actually makes it so that there’s no air inside the chamber at all, which means that sound can’t be created. It’s pretty chilling to hear that sort of silence (even if we hear silence all the time).
Even if he taps on the glass, we get nothing. Space is so quiet.
