Series / Space: 1999

Go To

"We are Mankind. We came from planet Earth, and we built this base, called Alpha, to learn more about space. But human error blasted this Moon out of the Earth's orbit. And so, we have traveled the Universe searching for a place to live."
Prof. Victor Bergman

This British TV series was created by Gerry and Sylvia Anderson, the creators of Thunderbirds and other "Supermarionation" fare as well as UFO, and was produced by Lew Grade's ITC Entertainment (in co-production with Italy's RAI during the first season, explaining the presence of Italian guest stars). It originally aired in the UK between 1975 and 1977, although several season one episodes were premiered in the US (like "Another Time, Another Place") and Australia (like "Ring Around The Moon").

It consisted of two seasons, each with a different approach; season one was slow-paced and cerebral, whereas season two had more "monster of the week" episodes. Its premise was simple: on September 13th 1999, a ridiculously smallnote  explosion blows the moon out of its orbit and accelerates it to a velocity sufficient to send it hurtling out of the solar system and travelling interstellar distances in improbably short times.


During this catastrophic event, the 300 persons crewing Moonbase Alpha avoid getting smeared into jelly; once things settle down a bit, they make the best of bad situation by surviving for at least three years with no means of support. They also deal with all the usual skiffy hackery — Aliens and Monsters, mysterious events, the works — without much thought to any serious science (or, often, common sense) in the resulting plots.

The massive production cost of the show meant that a network sale in the USA was more-or-less essential. Lew Grade, the head of ITC, pulled defeat from the jaws of victory by raising the asking price at the last minute in negotiations with a previously enthusiastic NBC, who called his bluff and passed. On learning of this, CBS and ABC also declined to buy it, and Grade was forced to sell it into syndication. Regardless, the ratings were successful enough that ITC commissioned a second season, with the provisos that there should be an American producer and the budget should be cut. The second season was also popular enough that a third almost happened.


A fan-produced featurette, "Message from Moonbase Alpha" (written by regular series writer Johnny Byrne, starring Zienia Merton as series regular Sandra Benes, using footage from the series and done with permission of the copyright holders, therefore almost being canonical) eventually established that the Moonbase crew found an Earth-like planet to live on.

Space: 1999 provides examples of:

  • Absentee Actor:
    • When producer Fred Freiberger came on board he set up a system where from time to time two episodes would be filmed simultaneously for scheduling purposes, specially scripted so that key regulars would have a minimal presence in one episode while taking centre stage in another. The most notable pairing was "Dorzak"/"Devil's Planet" - Martin Landau does not appear at all in the former, while he's the main character in the latter.
    • Sandra is missing from most of the second season, because Zienia Merton left after three episodes. She was later asked to return when both Martin Landau and Barbara Bain would be missing from the same episode, leaving it without any of the regulars from season 1. She appeared in some but not all of the remaining season 2 episodes.
  • The Ace:
    • In "Dragon's Domain", Koenig says Tony Cellini used to be this, before the Ultra Probe mission messed him up.
    • Tony Verdeschi comes across as this in Season Two.
  • Action Girl: Maya is quite good at hand-to-hand combat when in her humanoid form, and some of her shape shifted forms are quite deadly.
  • Adam and Eve Plot: What ends up happening to Luke and Anna on "The Testament of Arkadia".
  • Aliens and Monsters: And a wide variety of Negative Space Wedgie flavors to choose from as well. Poor Moonbase Alpha is Always Doomed.
  • Aliens Speaking English:
    • Some even write in English.
    • A LOT of the aliens have hilariously odd names, especially for those who live in the UK. Psychons ("The Metamorph") get a pass due to the nature of the plot; however the villain of "The Infernal Machine" being named Gwent (for those who don't know, a council in Wales, though this may have been an inside joke on the part of the mostly British production team), the entire episode "The Rules of Luton" (Luton is a town just outside London), and "One Moment of Humanity", which features aliens called the Vegans are noteworthy examples (though in the last case, Vega is the name of a real star, and authors like James Blish had used the name to refer to aliens from Vega's solar system long before the common word "vegan" came into use).
    • In "The Rules of Luton", it is first played straight, then subverted, and finally justified:
      • The Judges of Luton (sentient plants) address Koenig and Maya in perfect English when sentencing them for the crime of killing plants and eating them.
      • Koenig's and Maya's sentence is a battle to the death against three other off-world criminals. The trope is subverted when Koenig tries to negotiate with these aliens in English - they don't seem to understand him, and are shown communicating between themselves using what sounds like grunts and growls.
      • In the final confrontation with the last surviving alien, he suddenly replies in English when Koenig address him. He immediately provides the justification: the Judges see it as fit that they should be able to communicate before killing each other.
  • Ancient Astronauts: In "The Mark of Archanon", the aliens of the week are found buried on the moon itself, where they've been in stasis for centuries.
  • And I Must Scream:
    • The fate of Commissioner Simmonds in "Earthbound".
    • Balor in "End of Eternity". Not only does he start the episode locked away for eternity, but at the end he's blown into vacuum.
  • Applied Phlebotinum: The Gravity Shields, for one, became important on various episodes (like "Black Sun"), and both Bergman (and later Maya) and/or Russell came with ideas to use some new device each week (the first two a scientific procedure or gadget, the latter a medical procedure or gadget).
  • Arbitrary Skepticism: After being out in space for so long and seeing all kinds of Aliens and Monsters, the Alphans still spend a good part of the first act of "The Troubled Spirit" finding it hard to believe that there is an honest-to-goodness ghost running around Alpha killing people, and that such thing as researching the psionic potential of humans is still done back on Earth. It is the fact that one of the Moonbase researcher's skepticism makes him interrupt a seance on the prologue that starts the whole mess.
  • Artificial Gravity: The moonbase is equipped with "gravity shields" that provide artificial gravity, let spacecraft take off and land on planets without refueling, and allow the moon to fly through a black hole. The shields stop working every time they would be detrimental to the plot.
  • Artistic License – Astronomy: All exterior shots of the moonbase are illuminated by bright sunlight, and always from the same angle — even when the moon is in deep space, light years from the nearest star.
  • Artistic License – Physics: This series is notorious for this.
    • For instance, Isaac Asimov complained that an explosion powerful enough to deorbit the Moon would have destroyed it.
    • Furthermore, the nuclear waste that exploded was located on the far side of the Moon, which meant that the moon would have been driven into Earth itself. This was somewhat handled in one episode novelization, which retconned Breakaway from being a massive nuclear "kaboom" to a more rocket-like reaction.
    • Also, the way the moon seems to encounter extra-solar planets every few weeks or so would not only have required it to move much faster than light, but on a trajectory with frequent course changes (star systems don't just line up like that) for which no explanation is given, though some episodes such as "The Black Sun" seem to suggest that the moon's trajectory may be influenced by wormholes and Hyperspace Lanes.
    • Additionally, despite the vast speeds needed to encounter so many planets, the moon then nearly stops near the planets for long enough to have the adventure of the week.
    • In "End of Eternity", Balor is blasted out into space, despite the rather obvious premise that the show is based on a moon-bound space station.
  • Backdoor Pilot: Interestingly enough, "Message from Moonbase Alpha" could be seen as one, with Johnny Byrne mentioning that he had a concept in hand for any potential investors about a continuation series focusing on the Alphans and their descendants, 25 years after Operation Exodus when the Moon came orbiting back towards their planet. Sadly, Byrne passing away means that the idea's future is very much unknown.
  • Big "NO!": Dionne has one in "The Last Enemy".
  • Billed Above the Title: Martin Landau and Barbara Bain.
  • Bridge Bunnies:
    • Most of the female personnel on Alpha seem to be either this or nurses. The only female regulars shown to perform any work of consequence are Dr. Russell, Sandra Benes and (in the second season) Maya. Sandra is clearly working in a subordinate position, though — and seems to have little to do other than scream, faint or both. She gets a little more to do later in season one and in the second-season episodes where she appears at all.
    • Some individual episodes have e.g. female scientists or female aliens playing an important role, but these characters are not recurring parts.
  • Captain's Log:
    • Dr Helena Russell, starting with season two.
    • Also used in two first season stories, "Dragon's Domain" (with Dr. Russell) and "The Testament of Arcadia" (with Commander Koenig). Unfortunately, in the case of "Dragon's Domain" that means several season two episodes (such as "The Metamorph") take place in the timeframe of season one...
  • Chuck Cunningham Syndrome: Paul Morrow, David Kano, and Tanya Alexander disappeared between seasons with no on-screen explanation (though a tie-in annual feature stated that Morrow was killed in an Eagle crash). Professor Bergman also disappeared between seasons, but not without explanation; a (deleted) dialogue exchange in "The Metamorph" (the opening episode of Season Two) confirms that Bergman died previously due to a spacesuit malfunction.
  • Comic-Book Adaptation: Numerous.
    • Charlton Comics published both a color comic and an adult-oriented black and white illustrated magazine (noted for copious Ms. Fanservice moments). One episode of the black and white comic is dissected here.
    • Power Records released several comic-and-record sets.
    • There was also a popular comic strip in the UK.
    • In the 2010s all of these were brought back in a remix/mashup form combined with new material for a series of graphic novels.
  • Compilation Movie: This series was edited into five of these (including the show's only two-parter, "The Bringers of Wonder", which became Destination Moonbase Alpha). Some additional material was also filmed for the first movie, Alien Attack (which compiled "Breakaway" and "War Games"). One, Cosmic Princess (compiling "The Metamorph" and "Space Warp" — interestingly enough, the events of both episodes happen days to weeks apart in series canon and are not connected, but the compilation makes it look like they happen one immediately after the other), was featured in an early season of Mystery Science Theater 3000.
  • Conflict Ball: "Missing Link" has several scenes of the men arguing over who should be in command while Koenig is in a coma. One would think that a base with a crew of over 300 would have a pretty clear chain of command for occasions like that.
  • Cool Old Guy: Victor Bergman. Omnidisciplinary Scientist, The Professor, mentor figure for Koenig.
  • Cool Starship:
    • The Eagle Transports, possibly the most realistic fictional TV spacecraft ever created. Ersatz 2001: A Space Odyssey Moon Buses.
    • And their military counterparts, the Mark IX Hawks from "War Games".
  • Cosmic Horror Story:
    • While the story as a whole may not be quite that bleak, many episodes touch on this. A great many of the threats that assail Alpha are alien intelligences that care absolutely nothing about their plight and actually see in them a solution to their problem. Often that solution would kill many if not all of the Alphans, and on a couple of occasions even destroy the Earth. The Alphans manage to beat them back, however, even if sometimes it has a great price.
    • On the flip side, sometimes benevolent aliens appear (and Koenig and Bergman firmly believe that something has helped them survive as long as they did, with the odds stacked so unfairly against them).
  • Custom Uniform of Sexy:
    • Downplayed for Dr. Russell. Despite her being the only female part of consequence in the first season, and Barbara Bain's obvious star status, she wears exactly the same uniform as everyone else - but unlike the other women's (which according to the producers were designed to de-emphasize their bodies), hers is almost skintight. Unlike the other women, she also seems to be wearing a bra which emphasizes her breasts. The result is that she looks much curvier than her colleagues.
    • When we first see Maya in the first episode of season 2, she is wearing rather extravagant Space Clothes, but as she joins the doctor as a female lead she dons the same uniform as everybody else. It is, however, cut slightly differently, to look a bit sexier than the standard issue.
  • Discovering Your Own Dead Body: In "Ring Around the Moon", Carter and Koenig discover each other's vacuum-preserved corpses in a crashed Eagle on the alternate moon.
  • Distant Finale: The "Message from Moonbase Alpha" featurette.
  • Everything Is an iPod in the Future: The interiors of Moonbase Alpha and the uniforms worn by the Alphans (especially the more unisex versions in season one).
  • Exact Words: In the episode "Earthbound", hibernating aliens en-route to Earth have programmed their ship to make a pit stop on the Moon. After the Moon was blasted into deep space, the ship duly diverts to land on the Moon anyway, even though the Moon is by this time light years from Earth, and maybe in another part of the Universe entirely.
  • Expanded Universe: Adaptations of the episodes were straight Novelizations at first (with multiple changes to make them both fit together within a novel and also some changes done between final shooting script and broadcast episode), then swinging towards expanding the universe as they went on with multiple original stories set between Breakaway and "Message from Moonbase Alpha". A trilogy of books ("Survival", "Alpha" and "Omega") even go as far as work on bringing Professor Bergman Back from the Dead (making the deleted line from "The Metamorph" canonical but performing changes about the situation where it happened) and stranding him away from Alpha for a while, making him the P.O.V. character of a conflict between an alien race and an invasion of the "dragons" from the episode "Dragon's Domain". The novels also expand the mythology of the "cosmic intelligence" encountered on "Black Sun" and referred to on other episodes (like "War Games").
  • Failure Is the Only Option: Any attempts by the Alphans to find a new place to live or to go back to Earth are constantly thwarted by an uncaring, overpowering universe.
  • Fanservice:
    • When the crew adopt, or are forced to adopt, native dress while visiting planets, those clothes sometimes are more a bit on the Stripperific side.
    • Maya has quite a few fight scenes where she performs high kicks while wearing a skirt, showing a lot of leg and just barely avoiding outright upskirt shots.
    • Some of the aliens encountered wear quite revealing clothes. An example is Maya, who wears a dress with Absolute Cleavage in her first appearance. Once she joins the crew she wears the same uniform as everybody else, of course.
    • In one episode, Sandra's uniform is torn open, leaving her entire back bare and revealing that she isn't wearing a bra.
    • In one episode, a crewmember is possessed by an alien that craves energy from the environment, which drives him to the base solarium to seek heat and light. This gives an opportunity for shots of bikini-clad women.
    • The second-season episode "The Taybor" starts with a scene in the solarium, which seems to be occupied only by women in skimpy bikinis.
    • Averted with the unisex uniforms of the first season, which were deliberately designed to avoid sexualizing the women. This was in marked contrast to the precursor UFO and most other Sci-Fi shows of the times. In the second season the women's uniforms are somewhat more feminine, with skirts as an alternative to trousers, though they still stay far short of the fanservice department.
  • Fashionable Asymmetry: Most Alpha personnel wear off-white uniforms, but with a left sleeve that's a different — sometimes jarringly different — color. This serves the purpose of differentiating various crew categories.
  • Fix Fic: The "Message from Moonbase Alpha" featurette.
  • Freeze-Frame Ending: Every episode, although when some end on shots of space it's not always easy to tell.
  • Gaussian Girl: In season two, almost every close-up shot of Dr. Russell is very soft-focus and low contrast. Commander Koenig also sometimes gets the same treatment.
  • Glamour Failure: The two-part episode "The Bringers of Wonder" has huge, disgusting aliens note  who mentally project an image of humanity to fool the inhabitants of Moonbase Alpha. They can only be seen in their true forms by commander Koenig (who has been subjected to an experimental medical treatment) or by someone looking at video recordings of them or affected by "white noise" auditory anesthesia.
  • Gravity Sucks: In "Black Sun", the eponymous Sun's gravity is dragging an asteroid onto an collision course with Alpha, then somehow dragging it back into space moments before collision. It's explained in the episode that the black sun is not draining power from Alpha; they are diverting all but utterly essential energy into the gravity shields to protect them.
  • Irony: Of the Tragic kind. Commissioner Simmonds in "Earthbound" doesn't want to leave to luck his one chance to come back to Earth on an alien ship with only one cryogenic unit left. So, he takes hostage the Alpha base and Captain Zantor to secure his spot. After this goes horribly wrong, Captain Koenig reveals that the one candidate the computer picked for the trip was... Commissioner Simmonds.
  • Human Alien:
    • Many aliens are suspiciously similar to humans. This goes to the point where "The Last Enemy" has aliens that are basically humans in biker jackets.
    • Averted for other aliens who are machine intelligences, bodyless Energy Beings, or godlike spirits.
    • Might have been justified with Maya, who is a Voluntary Shapeshifter, except that she cannot hold a form for long, so her humanoid form is her true form.
  • Humanity Came From Space: In "The Testament of Arkadia", the Alphans find the original human homeworld.
  • Humans Are the Real Monsters: The Alphans encounter many Higher-Tech Species (usually of the Crystal Spires and Togas sort) who fear contamination or conquest by our backward, warlike species.
  • Infinite Supplies:
    • While Alpha has its own mining and production facilities, this isn't enough to avoid the trope.
    • Averted in the Season One finale, "Testament of Arcadia". Commander Koenig tells the fanatics who want to settle on a dormant planet that the amount of supplies that they'd take would doom the rest of the Alphans. Justified in that whatever force has diverted the Moon towards the planet Arcadia has also drained the Moonbase's energy supplies to a critical level, bringing their food production capabilities to a screeching halt.
    • This also includes a lot of the changes between season one and two. You can perhaps justify the new jackets, tools and weapons away as just something they already had in storage, but somehow they found the resources to install/renovate whole sections and departments.
  • Jump Scare:
    • Invoked in many episodes making the show surprisingly frightening, especially for younger viewers. Typically a visual shock would be coupled with the sudden sound of screaming. Notable examples include the paintings in "End of Eternity", and the burned ghost in "Troubled Spirit".
    • "The Immunity Syndrome" also attempted it with the Skeleton Crew reveal.
  • Lighter and Softer: The second season, to the point of Mood Whiplash for some viewers (given the somewhat pessimistic tone of the first).
  • Limited Sound Effects: The alien sound effects were rather good. However, they soon became rather familiar, with everything from a Negative Space Wedgie to an planet-based lifeform making the same sound across two seasons.
  • Mad Scientist's Beautiful Daughter: Maya's role in the episode where she's introduced, "The Metamorph". She has full confidence in her father Mentor's good intentions, until Koenig convinces her he's a dangerous madman. Then she turns coat.
  • Maybe Magic, Maybe Mundane: There is never a direct answer about what made the Moon change course towards Arkadia, remain in orbit for some time, drain a large amount of power from Moonbase Alpha, and then send it back on its merry way; or if the beings that lived on Arkadia are really Ancient Astronauts (or more specifically humanity's ancestors); or if Luke's and Anna's sudden bout of fanaticism is actually their own choice. What remains is a tale pretty similar to that of Adam and Eve.
  • Misplaced Wildlife: "The Metamorph" shows Mentor having a "lion" on an alien planet. It is later shown that said lion is a form assumed by Maya, who also assumes the forms of other Earth animals. It is not explained how she can know what these animals look like.
  • Monster of the Week: The second season became this, upping the action quota and de-emphasizing the psychodrama, to the dismay of some fans and the delight of others.
  • Neck Lift: Peter Bowles as Balor in "End of Eternity".
  • No Immortal Inertia:
    • The youthful villain of the episode "The Exiles" has spent 300 years in cryosleep; part of the technology involves a membrane, so thin it's invisible, covering his body. When Helena claws at the membrane, the years quickly catch up to him and he dies of old age.
    • Also done in the episode "Death's Other Dominion": something about a certain ice world kept the survivors of an exploratory ship unaging for centuries. When one of them tries to leave... the effect is quite gruesome, and the fact that he's holding Helena's hand at the time doesn't help.
  • No Pronunciation Guide:
    • The pronunciation of "Koenig" is all over the place. Depending on who is talking it's either "Kay-nig", "Ko-nig" or "Kuh-nig" (approximating the original German pronunciation). The commander himself pronounces it "Ko-nig".
    • Helena isn't immune either; being called "HELLena" or "HeLEEna" at various points.
  • Now or Never Kiss: Tony Verdeschi and Maya in "The Beta Cloud", along with him telling her that he loves her, which later comes back to haunt him.
  • Obstructive Bureaucrat: even before his definitive Face–Heel Turn, Commissioner Simmonds is only too willing to undermine Koenig, including offering to punish Koenig in front of alien guests.
  • Omnidisciplinary Scientist:
    • Professor Bergman, who is expected to have answers to any conceivable scientific or philosophical question.
    • In the second season Maya takes over this role.
  • Operation: [Blank]: "Operation Exodus", the plan to evacuate Moonbase Alpha. The struggle to locate a proper planet to evacuate the Alphans to is an important part of the plot in many episodes.
  • Opposite-Sex Clone: How Maya escaped from "The Taybor":
    Hag-like Maya: All right, Taybor. I will stay with you. It will be your pleasure to look at me in this form, a female reflection of yourself — forever!
  • Power Perversion Potential: Deliberately invoked and lampshaded by Maya, and played primarily for comedic value.
  • Pre Cap: The introduction to each first-season episode contains a montage of action shots from the episode, often of Eagles blowing up or people being thrown across rooms by explosions. This gives away nothing of the plot since it is presented without context. This is similar to the brief pre-title sequence used in the Anderson's Thunderbirds, and their only re-use of the idea.
  • Promotion to Opening Titles: Prof. Victor Bergman soon got his own appearance in the opening credits.
  • Recycled Soundtrack: And then some, with music from other Gerry Anderson shows (and assorted library pieces) being used to bolster the few episode scores Barry Gray composed for season one. (Derek Wadsworth also only did about five episodes in season two, and they were reused as well.)
  • Red Shirt: When a previously unknown face is seen in an Eagle cockpit, there's a large chance that Eagle will blow up.
  • Remember the New Guy?: Tony Verdeschi and Bill Fraser in Season Two.
  • Retool: From Season One to Season Two, into a more "action-packed" series and less cerebral plots. Also removing some of the main characters of said first season, some of them unexplained.
  • Reverse Polarity: in "Black Sun", the innovation behind Bergman's protective shield is to reverse the "pressure" of the Black Sun, instead of just negating it. How reversing differs from negating is not explained.
  • Running Gag: In season 2, Tony Verdeschi's terrible attempts at brewing beer.
  • Sci-Fi Writers Have No Sense of Scale:
    • The moon is variably described as being billions of kilometers, miles, and light-years from Earth, resulting in roughly equal difficulty in returning despite the fact that the first case would put the moon closer to Earth than Saturn, while in the latter case the moon would be vastly more distant from the Milky Way galaxy than the Great Wall, currently the largest known feature of the universe.
    • The moon passes between star systems at speeds fast enough to go through a star system per week, yet remains close enough to each and slow enough to reach a planet via shuttle for days at a time.
    • In "Black Sun", a survival Eagle is equipped with 5 weeks' supplies. As a sublight vehicle, there is no chance it will get anywhere in five weeks. They also intend that a gravity shield which protects Alpha will slow the approach of the entire Moon to the Black Sun (though, to be fair, neither Koenig or Bergman were really expecting it to work for very long).
  • Screaming Woman: frequently. Somewhat justified, since none of the crew signed on expecting the dangers they encounter. If no woman was present, a screaming man often made an acceptable substitute. Screams were sometimes overdubbed, leaving you wondering who it was who screamed.
  • Shiny-Looking Spaceships: Averted with the Eagle Transporters, thoroughly unglamorous work vehicles, kind of like dump trucks in space.
  • Skeleton Crew
    • "The Testament of Arkadia" had a cave with skeletons seated around a table.
    • "The Immunity Syndrome" plays straight the 'turn the captain's chair round to reveal the corpse' trope. In context it wasn't much of a surprise, so of the three fully grown men present, one wonders which it was who screamed..
  • Slurpasaur: In the episode "New Adam, New Eve", in a change from the usual People in Rubber Suits, giant lizards are encountered in a cave. Commander Koenig makes short work of them with his laser.
  • Space Clothes: Not as bad as some examples, but the unisex, beige jumpsuits are still very '70s. The second season actually manages to tone this aspect down by adding a jacket to the basic moon base uniform.
  • Space Is Noisy: Spectacularly in "The Last Enemy".
  • Spell My Name with a "The": Inverted for the Moonbase's main computer which is called just "Computer" (even on some moments where adding a "the" would be correct) by the characters.
  • Spiritual Successor: The moonbase setting, with the living quarters, control room and Eagle launch pads, seems like an expanded version of the moonbase in UFO. The original concept of the show was a Moonbase-centric, 1999-situated continuation of UFO, but in the actual show the subject matter and typical plots are very different.
  • Starfish Aliens: Any of the alien encounters that isn't a Human Alien or Rubber-Forehead Alien.
  • Stock Sound Effects: A Main Mission Red Alert alarm (heard in "Black Sun") sounds exactly like a tape recording of an antiquated mechanical alarm played through a bad loudspeaker.
  • Sudden Name Change: Sandra goes by the name Sandra Benes for the entire first season and the first episodes of the second season. After her absence from the cast for part of the second season, she is renamed to Sahn, with no explanation given. This could simply be a pet name for "Sandra", but in late season two episodes her name tag says "Sahn", with no surname. A possible explanation is that the producers wanted to portray her as an Asian rather than a European (the actress was half English, half Burmese and could pass as both).
  • Teach Him Anger: A peculiar example in "A Moment of Humanity". The reason why a robotic takeover of a planet has not gone as far as to kill their masters is because they don't know how to feel (or act) violently, so they abduct some of the Alphans and try to force them (in various ways, including seduction) to act violent around them so they can learn.
  • Terra Deforming: In one episode, the Alphans make contact with Earth, where it's a couple of centuries later due to relativity or something, and the entire population lives in domed cities because the outside environment is toxic. That exact phrase "Who needs nature" has become something of a Catchphrase, and you get the sense that nobody on Earth is too bothered about the loss of the ecosystem, in a manner similar to Silent Running.
  • Token Minority:
    • Ben Ouma, Moonbase Alpha's computer expert in "Breakaway", the first episode. Personal conflicts with the rest of the cast actor meant that actor Lon Stratton only appeared in one episode. Rather than recast the role, the character of Ouma was replaced with David Kano.
    • David Kano, Moonbase Alpha's computer expert in the rest of the first season, was played by Jamaican-born Clifton Jones. He averts his "mere token" status fairly well for a '70s series, and he certainly gets a lot more to do per episode than, say, Lt. Uhura.
    • Doctor Matthias, as well, has an important role in many episodes, being one of only two doctors on the base. Unlike Kano he returns for season two, although the character only appears in two episodes of the final season, making him the only black person on Alpha.
    • Sandra is a curious case. Her actress, Zienia Merton was half Burmese, half English, and in the later episodes of the second season the creators seemed to try to emphasize her Asian roots with a different makeup and hair style, even renaming her to Sahn.
  • 20 Minutes into the Future:
    • The story kicks off on September 9th, 1999.
    • "Voyager's Return" deals with an interstellar space probe launched from Earth in 1985.
  • Vapor Wear:
    • The thin fabric of the first-season uniforms makes it rather obvious that most of the women aren't wearing bras. This is not played for fanservice, and is not as noticeable with the thicker uniforms in the second season.
    • In one episode, Sandra suffers Clothing Damage that shows that she isn't wearing anything under her uniform.
    • The dress worn by Maya in her first appearance at first appears to have a bare back and Absolute Cleavage; in fact, the top part is made of nude-coloured fabric, but so sheer that it is obvious that there is no undergarment beneath.
    • Some of the clothes worn by female aliens, or by female Alpha crewmembers when adopting native dress, are cut in a way that implies this.
  • Voluntary Shapeshifting: Maya, who has the ability on her own. Her father, who's played by BRIAN BLESSED, has a computer that can do this to larger objects and, potentially, a whole planet.
  • Wagon Train to the Stars: With the added problem that there is no way of controlling nor stopping this train.
  • We Will Not Have Pockets in the Future: The uniforms conspicuously lack pockets, probably because it would ruin their lines. Nobody ever seems to need to carry around any small objects.
  • What Happened to the Mouse?: The first baby born on the moonbase in the episode "Alpha Child" is never mentioned again. This is an inevitable consequence of Space: 1999 being written, as was the norm back then, to be shown in any episode order after the scene-setting episode 1.
  • X Days Since: Episodes in the second season usually begin with the narration "X days after leaving Earth's orbit". The totals, however, frequently don't agree with numbers used during the first season, or with each other.
  • Zeerust:
    • The main computer is pictured in a way typical of the time before the public was exposed to computers: it seems to be a sort of oracle that can solve any problem given enough input data.
    • On the other hand, the input and output devices used by the computer are very primitive: enormous wall-mounted keyboards (with unmarked keys) that seem to require experts to operate (the fact some people spontaneously develop the capacity to input information on Computer at all — let alone at an insanely quick speed — is the first sign that something is not right on a couple of episodes), and output printed on narrow paper tape that has to be torn off and read aloud by an operator.
    • Many shots of high-tech equipment featured the large, open-reel tape drives typical of 1970s computers (but in real life made obsolete long before 1999).
    • On the same page, it's easy to notice that various "portable terminals" that appear throughout the series (such as for example on "Testament of Arcadia" ) are actually calculators of the type that were cutting-edge technology in 1975.
    • The first season's beige, unisex uniforms with flared trouser legs and broad, shiny belts — and the no-bra look for the women — seem very much like The Seventies today.

Trope-based episodes:

  • Worth It: Part of the speech that gives the Title Drop to "A Moment Of Humanity": for one of the humanoid robots to feel it, it believes as it dies, was worth the destruction of his entire race.
  • Yandere: Shermeen in "A Matter of Balance"
