Jupiter II - Spacecraft featured on the science fiction series LOST IN SPACE/CBS/1965-68. Launched on October 16, 1997, the "Jupiter II" was bound for the Alpha Centauri galaxy with hopes of finding a planet to support the burgeoning population of earth. Its crew included: Professor John Robinson (Guy Williams), his wife, Maureen (June Lockhart), their eldest daughter, Judy (Marta Kriston), younger daughter, Penny (Angela Lockhart), young son, Will Billy Mumy), the ship's pilot, Major Donald West (Mark Goddard) and a reluctant stowaway, Dr. Zachary Smith (Jonathan Harris), an enemy agent whose sabotage attempt got the ship hopelessly lost in space.

In appearance, the Jupiter II was shaped like a flying saucer with a ring of lights on its underbelly. It's interior consisted of two levels. The upper level housed the guidance controls and suspended animation tubes originally designed to hold the hibernating crew as they traveled across the galaxy. The lower deck featured living quarters, galley, laboratory, a storage area for the ship's bulky robot, and a compartment containing a shuttlecraft vehicle called the "Space Pod" used for ship-to-planet travel. A small elevator platform and ladder  provided  passage  between levels.

TRIVIA NOTE: The special effects team of  L.B. Abbott  and  Howard Lydecker designed a variety of models of the ship including a  full-scale  model for interior shooting and small-scale models for space travel scenes.

The Lost in Space jigsaw puzzle made by Milton Bradley in 1965 featured a full color photo of the Jupiter II.

A new and improved Jupiter II design appeared in the motion picture remake Lost in Space (1997). See also - ROBOTS: "Robot the robot"
