Editing Lost in Space (section)

==Series synopsis==
===Overview===
On October 16, 1997, amidst overpopulation on Earth, the United States is gearing up to colonize space. The ''Jupiter 2'', a futuristic saucer-shaped spacecraft, stands on its launchpad undergoing final preparations. Its mission is to take a single family on a five-and-a-half-year journey to an Earth-like planet orbiting the star [[Alpha Centauri]].

The Robinson family consists of a married couple, John ([[Guy Williams (actor)|Guy Williams]]) and Maureen ([[June Lockhart]]), and their three children: Judy ([[Marta Kristen]]); Penny ([[Angela Cartwright]]); and Will ([[Bill Mumy]]). John is a professor. The family is accompanied by U.S. Space Corps Major Donald West ([[Mark Goddard]]). The Robinsons and Major West are to be [[Cryogenics|cryogenically frozen]] for the voyage, and they are set to be unfrozen when the spacecraft approaches its destination.

Dr. Zachary Smith ([[Jonathan Harris]]), a physician working for ''Alpha Control'', which is conducting the launch, is revealed to be a saboteur working on behalf of an unnamed nation or organization, with which he communicated under the code name ''Aeolis-14-Umbra''. After disposing of a guard who catches him aboard the spacecraft, Smith reprograms the ''Jupiter 2''{{'}}s [[Robot (Lost in Space)|B-9]] environmental control robot ([[Bob May (actor)|Bob May]], voiced by [[Dick Tufeld]]) to destroy critical systems on the spaceship eight hours after launch. To his horror, however, Smith becomes trapped aboard, and after launch his extra weight throws the ''Jupiter 2'' off course, causing it to encounter asteroids. This, plus the robot's rampage, causes the ship to prematurely engage its hyperdrive, and the expedition becomes hopelessly lost in the infinite depths of outer space.

===Season 1===
The first season begins as the Robinson family and their pilot are about to set out from Earth for a planet circling the star Alpha Centauri. Dr. Smith saves himself from the post-launch crisis of his own making 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.

===Season 2===
At the start of the second season (from this point on filmed in color), the repaired ''Jupiter 2'' launches into space once more, to escape the destruction of Priplanus following a series of cataclysmic earthquakes. The Robinsons crash-land on a strange new world, to become planet-bound again for another season.

===Season 3===
In the third season, a format change was introduced. In this season, the ''Jupiter 2'' travels freely in space in seven episodes, visiting a planet but leaving at the end, or encountering an adventure in space. They visit new worlds in several episodes, with both crash and controlled landings, as the family attempts to either return to Earth or else at least reach their original destination in the Alpha Centauri system. A newly introduced "Space Pod" provides a means of transportation between the ship and passing planets, allowing for various escapades. This season had a different set of opening credits and a new theme tune, which had been composed by [[John Williams]] as part of the show's new direction.<ref>{{cite news |last=Greiving |first=Tim |url=https://www.latimes.com/entertainment/arts/la-et-cm-john-williams-early-life-20180718-story.html |title=John Williams' early life: How a NoHo kid and UCLA Bruin became the movie music man |work=[[Los Angeles Times]] |date=July 18, 2018 |url-status=live |archive-url=https://web.archive.org/web/20190206065718/https://www.latimes.com/entertainment/arts/la-et-cm-john-williams-early-life-20180718-story.html |archive-date=February 6, 2019 |access-date=April 11, 2019 }}</ref>
