The pilot episode that introduces the main cast and sets the stage for the series. Located on the moon is Moonbase Alpha, a multinational scientific research facility. One of its duties is to also monitor and coordinate the activities surrounding two large lunar dumping sites where nuclear waste from Earth is disposed of. The Alphans are trying to launch a fast-tracked manned probe to an 'approaching' planet named Meta. The Meta Probe is in jeopardy since two of the mission crew have come down with a mysterious illness. The Alphans tie the illness to the nuclear waste about the time the smaller site unexpectedly explodes. While the Alphans try to avert a similar explosion in the larger waste site, it explodes also, and pushes the Moon out of the Earth's orbit, leaving the Alphans stranded on a moon destined to wander the universe.

Originally conceived as a new season of UFO
(1969). The plot would have had the aliens from that series trying to destroy SHADO's moon-base by knocking the moon out of orbit. See more
A tremendous explosion on "the dark side" of the Moon supposedly throws the Moon out of orbit and into deep space. There really isn't a "dark side" to the Moon. Though it is true that only one side of the Moon ever faces the Earth, all parts of the Moon get sunlight as it orbits Earth every month. Even if they meant the "far side" of the Moon, the situation is no better. If they actually meant "dark" side (ie: the side facing away from the Sun at that moment) then the explosion would have flung the Moon into the Sun. If they meant to say "far" side, then the explosion would have flung the Moon into the Earth. See more
Professor Bergman, it's Jim Nordstrom. We've just passed through the laser barrier, and we should be ready to start Doctor Russell's manual check on the radiation seals in a couple of minutes.
