In 1999, Moonbase Alpha, nestled in the Lunar crater Plato, is a scientific research colony and watchdog over silos of atomic waste from Earth stored on the Moon's far side. On September 13, 1999, magnetic energy builds to cause an explosive chain-reaction of the waste, blasting the Moon out of Earth orbit and off the plane of the ecliptic, out of the Solar System. The inhabitants of Moonbase Alpha are unable to return to Earth and must survive on their wandering Moon as it is displaced further into unknown space by freak space warps. Along the way, they are joined by an alien woman with the ability to change herself into any living creature at will. Written by Kevin McCorry <>

A third season of 13 episodes was planned, with production set to start in the autumn of 1977, however low sales of the series in America forced a last-minute cancellation. See more »


In many episodes, Eagle pilots fly missions in their usual gray uniforms; very rarely do they wear pressure suits ("spacesuits"), and they almost never wear helmets. Since all of their missions involve flying through vacuum, this is a ridiculous risk to take. See more »


Prof. Victor Bergman: [last message before evacuating Alpha] 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. Now, we can no longer live here, and we go to face an uncertain future on the planet that has nearly destroyed us. You, whoever you are, who find this empty vessel of Alpha, come and seek us out, if we still exist. Come and ...

When I think of Space 1999 I think of South Side Elem School, Schwinn Sting-Ray 5 Speed Bikes, My dad's Navy Blue 1974 Oldsmobile Cutlass Supreme & my parents big 25in cabniet model Zenith TV. When this show was on the air it was the hottest thing to hit TV since the original Star Trek. I remember all the toys, the big plastic EAGLES and the walkie talkie communicators and battery powered laser guns. Catherine Schell as MAYA still holds the Sexiest Alien girl ever Trophy in my opinion. I was very sad to learn from this site that Tony Anholt passed away of a brain tumor in July 2002. To this day I am at a loss as to why this series had such a short life. I suspect production costs in the UK sank it. To any of the former cast & crew who may read this, Martin, Barbara, Nick, Catherine, & so many others thanks so much for the memories and for an outstanding job. I own all the DVDs now and show it to friend's kids every now and then and they LOVE IT !
