An historic day. The Robinsons - John, Maureen, Judy, Penny and Will - become Earth's first family of outer space, on its way, accompanied by pilot Maj. Don West, to colonize a planet circling Alpha Centauri; however, Dr. Smith, as an enemy agent of a foreign power, means to set them on a course of doom by reprogramming the robot to destroy their ship, the Jupiter 2, eight hours in space. The unfortunate doctor winds up caught in his own treachery and hurls off into space with the Robinson party. His excess weight first throws the ship off course, then, with the robot coming to life and bashing all the controls, they all become "hopelessly lost in space." Written by

For this episode, John Williams (as Johnny Williams) wrote a good deal of incidental music, much of which would be re-used throughout the course of the series. Especially notable is the music that accompanies the zero-gravity scene. Williams dubbed it "The Weightlessness Waltz" and it would be used again many times for fanciful sequences. See more

The Robinson family was selected from more than two million volunteers for its unique balance of scientific achievement, emotional stability and pioneer resourcefulness. They will spend the five and a half years of their voyage frozen into a state of suspended animation, which will terminate automatically as the spacecraft enters the atmosphere of a new planet.
