(October 2017) (Learn how and when to remove this template message) </Td> </Tr> <P> On October 16, 1997, 32 years in the future from the perspective of viewers in 1965, the United States is about to launch one of history's great adventures: man's colonization of space . The Jupiter 2 (called Gemini 12 in the unaired pilot episode), a futuristic saucer - shaped spacecraft stands on its launch pad undergoing final preparations . Its mission is to take a single family on a five - and - a-half - year journey (altered from 98 years in the unaired pilot) to a planet orbiting the nearest star, Alpha Centauri (the pilot show had referred to the planet itself as Alpha Centauri but this error was corrected for the series), which space probes have revealed possesses ideal conditions for human life . All of this is presented as a news report of a real space expedition, with news commentators informing us of the missions backstory . </P> <P> The Robinson family, supposedly selected from two million volunteers for this mission, consisted of Professor John Robinson, played by Guy Williams, his wife, Maureen, played by June Lockhart, their children, Judy (Marta Kristen), Penny (Angela Cartwright), and Will (Billy Mumy). They are accompanied by their pilot, U.S. Space Corps Major Donald West (Mark Goddard), who is trained to fly the ship when the time comes for the eventual landing . Initially the Robinsons and Major West will be in freezing tubes for the voyage, with the tubes opening when the spacecraft approached its destination . Unless there is a problem with the ship's navigation or guidance system during the voyage, Major West was only to take the controls during the final approach and landing on the destination planet, while the Robinsons were to strap themselves into contour couches on the lower deck for the landing . </P> <P> Other nations are racing to colonize space, and they would stop at nothing, not even sabotage, to thwart the United States's effort . It turns out that Dr. Zachary Smith (Jonathan Harris), Alpha Control's doctor, and later supposedly a psychologist and environmental control expert, is moonlighting as a secret agent for one of those competing nations . After disposing of a guard who catches him on board the spacecraft, Smith reprograms the Jupiter 2's B - 9 environmental control robot (voiced by Dick Tufeld) to destroy critical systems on the spaceship eight hours after launch . Smith, however, unintentionally becomes trapped aboard at launch and his extra weight throws the Jupiter 2 off course, causing it to encounter a meteor storm . This, plus the robot's rampage which causes the ship to prematurely engage its hyperdrive, causes the expedition to become hopelessly lost in the infinite depths of outer space . </P>
