  • How is Voyager's vintage technology still flying?

    How is Voyager's vintage technology still flying?
    Apr 25 2023
    Voyager 1 and Voyager 2 launched back in 1977 with only a five-year mission to take a gander at Jupiter and Saturn’s rings and moons. Obviously, the Voyager spacecrafts have persisted a lot longer than five years: 46 years, to be exact. They’re still careening through space at a distance between 12 and 14 billion miles from Earth. So how have they lasted four decades longer than expected? -- Follow us on Twitter: https://twitter.com/AskPopSciPod Produced by Jess Boddy: https://twitter.com/JessicaBoddy Music by Billy Cadden: https://open.spotify.com/artist/6LqT4DCuAXlBzX8XlNy4Wq Art by Katie Belloff: https://twitter.com/Katie_Bellz Learn more about your ad choices.
