This part of the show Space Odyssey: Voyage To The Planets was never shown on American TV. In the condensed version, the crew recover from the tragedy which struck them when crew medic John Pearson succumbed to terminal lymphoma induced by exposure to solar radiation, and decide that Saturn was far enough. They then head home.
This is from the British version - where the crew make the decision to head on out to Pluto instead. This is the scene of their arrival and exploration of the outermost planet.
