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.

Gerry Anderson wanted to make his own version of Star Trek. In the opening episode you might even think he almost succeeded.

Although made in Britain and funded by ITV. This first episode had an American writer and director. Two main stars of the show were American as well. Then husband and wife team of Martin Landau and Barbara Bain.

It is September 1999. Commander John Koenig has been sent to Moonbase Alpha as a troubleshooter. The moon is a dumping ground for nuclear waste.

Koeing needs to urgently find out why some form of madness has been affecting some of the astronauts as they prepare to launch a probe to the Planet Meta.

The crew finds out that magnetic radiation from the nuclear waste has caused the illness. The nuclear waste causes an explosion on the dark side of the moon that rips it away from Earth's orbit.

Moonbase Alpha is now drifting in space looking to find somewhere safe to go to.

This first episode clearly had a lot of money spend on it. The special effects are very good, there is use of miniaturised television screens. There are a lot of antiseptic white sets which is rather handy, as there are a lot of white men standing or failing about in the multinational crew.

Professor Victor Bergman (Barry Morse) provides calm and science. The science is definitely a bit hokey. Bain looks like she has been given an overdose of Valium. Philip Madoc's Russian commander character sounds like he grew up in the Rhonda Valley.
