The Jupiter 2 is a rare example of a once common archetype from science fiction - the 'flying saucer'.(see the original 1960s version of the ship, which is illustrated here)
This ship is designed to transport a single family to nearby Alpha Centauri in order to start a colony. Cryosleep tubes are therefore installed on the ship, as are a 'space pod' (shuttlecraft) and 'chariot' (amphibious, caterpillar-tracked vehicle).
Lost in Space was produced as a TV series by Irwin Allen, and ran for three seasons between 1966 and 1968. A reimagined movie version was produced in 1998. A further reboot of the show is currently in development.
