Cue Simon & Garfunkel — Mars is all about the sound of silence.

NASA’s Perseverance rover has been recording the ambient sounds on Mars for the past year, and scientists have trimmed those recordings to a five-hour “Martian playlist.” The main takeaway? It’s very quiet on Mars. In fact, the few natural noises on the Red Planet, including wind, are about 20 decibels quieter than the same noises on Earth.
