The Source That Powered Voyagers For 44 Years In Space
The two Voyager spacecraft have been exploring the cosmos for more than 40 years. Today, Voyager 1 is the farthest spacecraft from Earth at more than 20 billion km. Even signals take more than 20 hours to get there. But have you ever wondered what kept these two spacecraft going? What’s the energy source that is powering the Voyagers? And most importantly, how long do we have before we lost contact with the two distant spacecraft? The second episode of the second season of the ‘Ever Wondered’ series will answer these questions.
