The first season begins as the Robinson family and their pilot are about to set out from Earth for a planet circling the star Alpha Centauri. Dr. Smith saves himself from the post-launch crisis of his own making by prematurely reviving the crew from suspended animation. The ship survives, but the damage caused by Smith's earlier sabotage of the robot leaves the crew Lost in Space. The Jupiter-2 crash-lands on an alien world, later identified by Will as Priplanus, where they spend the rest of the season and survive a host of adventures. Smith remains with the crew and acts as a source of comedic cowardice and villainy, exploiting the eternally forgiving nature of Professor Robinson.
