Free sound samples from NASA

Would you like to hear what lightning on Jupiter sounds like? How about the beeping sound transmitted by Sputnik in 1957, or the first sound recording taken on Mars? Head over to NASA’s ​​Audio and Ringtones page, where you can listen to dozens of recordings. My favorite is Juno’s 2021 flyby of Jupiter’s moon Ganymede, which sounds like an old science fiction radio play. — MF
