Welcome to another Science Hindsight 2020 episode. The Voyager 2 spacecraft has been in the news recently, which made me want to revisit the origins of this historic mission. Voyager 1 and 2 launched in 1977 and have helped to give us a better understanding of our solar system, visiting Jupiter, Saturn, Uranus, and Neptune. Before leaving the solar system entirely, Voyager 1 looked back and snapped the famous 'family portrait' with the iconic Pale Blue Dot photo. For the 30th anniversary of the Pale Blue Dot, the photo has been remastered, and this episode follows the journey of these incredible spacecraft as they continue to transmit data almost 12 billion miles away.
