The Jupiter 2 is the main spaceship on Lost in Space. It resembles a flying saucer on the exterior with a dome on top and a large viewport. The hull of the ship is made of titanium, although parts of it, including the hatch, are made of cosmium steel. In the first few episodes, it glows in most flight scenes, but this was dropped later on. It was launched on October 16, 1997, towards a planet of the star Alpha Centauri for the purpose of colonizing it. Its crew consisted of the Robinson family, Major Don West , and an enviormental control The Robot. The Jupiter 2 mission cost about 30 billion dollars.
