Eli5: Are satellites really ‘beeping’ and why?
In: Engineering
Nope. A speaker would be extra weight and entirely pointless since sound can’t propagate in space.
It costs a lot of money to launch a satellite, every gram of weight costs money, you wouldn’t put a speaker on it since it would be a waste of weight/space.
In TV and movies they want to show “hey this is a satellite and it’s transmitting” so they add sound effects
One place you **will** find a speaker in space is Elon’s Tesla Roadster, an entire commercial model car floating around in orbit, the car’s stereo system is permanently looping the song “Space Oddity”.. but you can’t hear it since sound doesn’t propagate in space.
