The orientation in which Jupiter, Saturn, Uranus and Neptune were in during the time was crucial to the mission as the gravity of these planets could be used to get further away from Earth with ease, this occurs once every 175 years. The Voyager space programme is regarded as most successful space exploration mission in human history and rightly so it has helped us discover and learn quite a lot about space. Both the probes are still functional as of 2023.
