Space 1999

September 9th, 1999: Commander John Koenig arrives at Moonbase Alpha to supervise a manned probe mission to the newly discovered planet Meta. Nine astronauts have been killed by a mysterious illness and Dr. Helena Russell is convinced that radiation is the cause. An investigation of the Moon's nuclear waste disposal areas reveals no sign of radiation leakage but intense heat is registered and Professor Victor Bergman suggests that increased magnetic output is the real threat. One of the nuclear waste areas explodes and the only way to avert a major disaster is to disperse the remaining nuclear waste canisters, but a sudden increase in magnetic radiation sets off a chain reaction which alters the Moon's gravitational field and throws the satellite out of Earth orbit.
