 Since the Voyager Science team released audio from interstellar space, I've seen a lot of questions about why we don't have more audio from deep space missions. I'm Amy Schirrititel, and this is a vintage space video. Unfortunately, no mission has ever successfully captured sound from space, but this isn't for lack of trying. NASA's Mars polar lander carried a microphone on board, but when it crashed in 1999, the microphone was destroyed and the whole mission came to an end. There was also a French mission designed just to capture sounds on the red planet, but it never flew. NASA's Mars Phoenix lander did carry a microphone which landed successfully on the surface, but the microphone never returned good data. So what we don't know what exactly space sounds like, scientists have been able to simulate what any sound would sound like on a different planet. They do this by taking atmospheric data and figuring out how the sound waves would move and change in a different atmosphere. In the case of Voyager 1, scientists were able to take information about the amplitude and frequency of plasma waves and turn that into audio. For more on sounds and space, check out the links below.
