(Star Trek: The Original Series，1966年-1969年)
《原初系列》在1966年9月8日于美国全国广播公司（NBC）首播，吉恩•罗登贝瑞制作，威廉•薛特纳（William Shatner）、李奥纳德•尼摩伊（Leonard Nimoy）、以及德佛瑞斯特•凯利（DeForest Kelley）所主演。它是一个描述一艘隶属于星际联邦（the United Federation of Planets）的星舰进取号（Enterprise，又译为企业号/奋进号）上的航员以及他们“勇敢地航向前人所未至的领域”（To boldly go where no one has gone before）的冒险故事。在一开始它并不成功，收视率低而且广告收入也不理想。然而，当这个节目第二季隐约出现了停播的恶兆时，忠实影迷们展开了一场前所未有的争取运动，说服美国全国广播公司继续制作第三季。最後一集于1969年6月3日首播。该电视系列剧在日後各台重播中受到惊人的欢迎。
为了将这第一个系列与日後其他系列作一个区分，这个系列在西方被称为Star Trek: The Original Series（星际旅行：原初系列，在台湾使用《星际争霸战》这个名称﹐在七十年代的香港译为《星空奇遇记》），缩写为ST:TOS或TOS。
也就是最早的ST，为了和后来的剧集区别开国外Fans在其名称后加了The Original Series，所以简称TOS，一共三季，开创了历史的经典之作，电影版的1-6可以看作TOS的延续，电视剧版原班人马。
Charles Augustus Howell was John Ruskin's secretary, agent and model for Dante Gabriel Rossetti, and exhumer of Lizzie Siddal. But he is also said to have been a master blackmailer and a forger of works of art.
A fictional village confronts a bizarre dilemma when their cemetery runs out of burial space, leading to uproarious situations as the townspeople unite to find creative solutions.
Cinnamon plays a long lost princess to prevent a regent from taking over in 'a small Baltic monarchy.' Of course, IMF's mission is to prevent a dictator from taking over a 'free' monarchy!
This 7-year series chronicled the adventures of the Impossible Mission Taskforce (IMF), a team of government spies and specialists who were assigned "impossible missions" by the unseen "Secretary". Although the cast varied over the years, the main characters included The Team Leader (Dan Briggs the first season, then Jim Phelps the other six), The Techno-Wizard (Barney Collier), The Strongman (Willy Armitage), The Master of Disguise (first Rollin Hand, then The Amazing Paris), and The Femme Fatale (Cinnamon Carter, Casey, Dana Lambert, Mimi Davis).
The series is best known for its opening mission assignment (conducted by a pre-recorded tape), the theme composed by Lalo Schifrin, the leader's selection of mission agents from a dossier, the opening briefing, the intricate use of disguises and a typical "mask pulloff" scene near the end of most episodes, and the relative lack of characterization of the characters.
Jim Phelps is the new leader of the Impossible Missions Force, with no explanation, or even reference made, about the departure of predecessor Dan Briggs. First up for Phelps is a mission involving the drug trade. Cresnik and Walters have cornered the heroin market and sell it at a handsome profit to gangs around the world. Phelps devises an operation which will drive a wedge between the heroin dealers and their customers.
