The Sounds of Mars

YouTube caption

NASA's Perseverance Mars rover carries two microphones which are directly recording sounds on the Red Planet, including the Ingenuity helicopter and the rover itself at work.

For the very first time, these audio recordings offer a new way to experience the planet.

Earth and Mars have different atmospheres, which affects the way sound is heard.

Justin Maki, a scientist at NASA's Jet Propulsion Laboratory and Nina Lanza, a scientist at Los Alamos National Laboratory, explain some of the notable audio recorded on Mars in this video:

"This is one of my absolute favorite sounds. This is the sound of a helicopter flying on Mars. We used this sound to actually understand the propagation of sound in general through the Martian atmosphere, and it turns out that we were totally wrong with our models. The Martian atmosphere can propagate sound a lot further than we thought it could."

From Dense Discovery: "Flip through video footage (like commercials, news, sports, talk shows, and much more) from the '90s in this wonderfully retro TV experience. (Or change the decade through the TV sets on the right and dip into the '60s, '70s, '80s, or 2000s.)
