Lost in Space (1965) Season 1

The astronaut family of Dr. John Robinson, accompanied by a pilot and a robot, set out in the year 1997 from an overpopulated Earth in the spaceship Jupiter 2 to travel to a planet circling the star Alpha Centauri. The Jupiter 2 mission is sabotaged by Dr. Zachary Smith (an agent for an unnamed foreign government) who slips aboard the spaceship and reprograms the robot to destroy the ship and crew. However, Smith is trapped aboard, and his excess weight alters the craft's flight path and places it directly in the path of a massive meteor storm. Smith manages to save himself 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.

01. The Reluctant Stowaway
Sep 15, 1965

In the year 1997 the Robinson family take off to colonize Alpha Centauri. A spy from a foreign country AKA Dr. Smith becomes trapped aboard trying to sabotage the project. The ship is whisked off course and into a meteor storm due to Dr. Smith's extra weight upsetting the navigational computers. Smith desperately tries to save himself by reviving the crew. The result: the Robinson family becomes lost in space.

However back at the Jupiter two, Dr Smith who stayed behind because he believed them to be lying, realises that the orbit is strange, bringing immense cold followed by extreme heat. He sends the Robot to tell them, and they then attempt to travel back to the Jupiter 2. However in their way is a huge in-land sea which previously had been frozen solid. The immense heat and cold make the vegetation charred. They survive the heat and return to the Jupiter Two where they are most safe.

15. Return from Outer Space
Dec 29, 1965

Lost in Space's only Christmas program. Will uses an alien transporter to send himself back to earth. However, many people believe the Robinson family to be dead after hearing the ship went off course. Nobody on Earth believes him, and they lock him up with the intention of sending him to a boys' home. Will escapes the family home he's in, and wanders around these clueless bunch of townspeople, but finds carbon tetrachoride — needed for the food processors on the Jupiter. Eventually he convinces another boy, Davey, to let him out, and let him return to the planet he came from. He returns to Priplanus with this bottle. Of course no one believes his adventures until he produces the bottle, plainly labeled as coming from Earth.

26. All That Glitters
Apr 06, 1966

In this retelling of "The Midis Touch", Dr. Smith gains the power to turn anything into platinum. Penny is given a gift by a thief on the run, who tells her to protect it for him. She and Dr. Smith discover that it leads them to a ring which, when worn, allows the person to turn anything to platinum, which Dr. Smith does and enjoys. However, when it turns even his food to platinum, he is unable to remove the ring, which is now a solid bar. He leaves the camp as he fears turning everything into platinum, and he will eventually starve to death. A galactic lawman is on the trail, looking for the stolen device to use for his own nefarious purposes.
