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
Did You Know?
Alpha Centauri, a.k.a. Alpha Centauri AB, is currently classified (as of 2012, at any rate) as a binary star, approximately 4.37 light years from Earth, with its two suns designated as A (the larger) and B (the smaller). Proxima Centauri, a.k.a. Alpha Centauri C, is .2 light years from Alpha Centauri AB. At one seventh the size, its sun is much smaller than ours and not visible to the naked eye, but its distance from Earth is 4.24 light years, making it the closest sun to ours. It was discovered in 1915. An Earth-mass planet had been detected in orbit around Alpha Centauri B, but, It is not in the habitable zone, orbiting very close to the host star. It's surface temperature is estimated to be 1200 °C (about 1500 K) - far too hot for liquid water and also above the melting temperatures of many silicate magmas. See more
When Doctor Smith revives Major West from suspended animation, he takes off the Major's right hand glove to attach a type of reviving mechanism. When West wakes up, Smith drags the groggy West to the flight panel so West can fly the ship. When the camera looks down at Major West's hands controlling the flight stick, he is shown wearing gloves on both hands not one. See more
