Filmed November 8th to the 19th 1974, but the episode ran short. New footage was added later (from February 25th to the 27th 1975, immediately after "The Testament of Arkadia" was finished shooting), including the scene with Dione in Sandra's quarters, as well as all scenes aboard Dione's spaceship at the episode's start. In addition, the originally-filmed ending was replaced, as the producers weren't satisfied with having Koenig simply giving Talos the coordinates of the Bethan gunship, sparing Alpha. A new ending was shot consisting of Koenig's sneaky ploy of taking matters into his own hands. See more
The moon has no atmosphere so when the Bethan gunship fires it's missiles over the moon-base towards the Deltans, there should be no noise, just flashes of light and maybe some vibration via the moon surface (but nowhere near as intense as is shown here). See more

We'll be in range to survey the left-hand planet in 24 hours.
Still too distant for visual analysis, but the spectrographic analysis looks promising.

Two planets. Be nice to have a choice, wouldn't it?
