1979 Newsround discusses Voyager-1
The Voyager-1 spacecraft may have become the first man-made object ever to leave our solar system but here's a taste of the stir it caused back in the 1970s.
This old footage from a 1979 edition of Newsround shows some of the first pictures sent back by the probe, which launched two years earlier.
In it Newsround presenter John Craven discusses the possibility of humans camping on Jupiter's moons and his guest talks about the potential for discovering bird life around the planet's rings.
