Moonbase Alpha and its inhabitants encounter members of a lost Earth Expedition on the far-flung world of Ultima Thule in Death’s Other Dominion.
Written by Anthony Terpiloff and Elizabeth Barrows, this episode first debuted on 2 October, 1975.
There’s no suggestion of where Ultima Thule is in the galaxy, and how long Alpha has been travelling, but that really isn’t the point of these stories. The survivors on the planet are led by Dr. Cabot Rowland (the always enjoyable Brian Blessed) who invites them to the surface, even as his ally, Jack Tanner (John Shrapnel) warns them away.
Gearing up for arctic conditions, Koenig (Martin Landau), Alan (Nick Tate), Russell (Barbara Bain) and Bergman (Barry Morse) go to investigate.
They are rescued from the snow storms by Cabot and his people, and we learn that they live for an eternity at a strange cost. They’ve been missing for fourteen years, and they haven’t aged much since that time, and they reveal for how long they have been there (more than fourteen years), and the physical results it has affected upon them.
The Alphans back at Moonbase attempt to get in touch with their landing party, but Cabot interferes, in order to execute a plan. Tanner tries to warn them, but he has also gone mad, and there is something strange going on with Cabot’s experiments.
As Koenig and his team attempt to come to terms with what they have learned about the residents of the planet Cabot makes his move on the Alphans, will the people of Ultima Thule rise up, finally? Will Bergman and Russell become Cabot’s new acolytes? And will the Alphans decide to stay?
It all comes to a conclusion when Cabot attempts to travel to Alpha aboard an Eagle to make his pitch. When he leaves the planet, and the ecosystem that is keeping him alive, and eternal, fails, horrifically.
Alpha continues onward.
Johnny Byrne pens Voyager’s Return which first aired on 9 October, 1975.
As they tumble through space, the moon comes across the Voyager One probe, powered by a Queller Drive, it emits a dangerous field which decimates one of the base’s Eagles (how many do they have?) and it is being followed by a fleet of ships from a planet ruined by the drive, with the intention of confronting those who destroyed their world.
The show was actually created before Voyager One was even launched so they were able to take liberties with it, including the creation of the dangerous Queller Drive.
Bergman wants to access all the information that Voyager may have, but Russell cautions against drawing too close because of the drive. Koenig comes up with the plan to land it on Alpha so they can examine it. Conveniently enough, the designer of the Queller Drive is aboard Alpha, under the name of Linden (Jeremy Kemp).
Linden’s creation claimed a number of lives including the parents of his assistant, Jim (Barry Stokes), who does not know Linden’s real identity. This adds a little dramatic tension to the story about whether or not the young man will learn who his boss is.
And we meet some more aliens, and again, Alpha takes everything in stride; no sense of wonder, awe or fear of the new life they have discovered.
These aliens plan to follow Voyager back to Earth, and destroy the planet, and all its inhabitants, wherever they may be, including on Moonbase Alpha.
Can Koenig come to a peaceful resolution? And honestly, after the moon broke orbit, what kind of shape can Earth be in anyway?
Linden is the problem, and the answer…
The moon continues on its journey through Space:…. 1999!
