"Where No One Has Gone Before" is the sixth episode of the American science-fiction television series Star Trek: The Next Generation, which originally aired October 26, 1987, in broadcast syndication in the United States. A high-definition, remastered version of the episode received a limited theatrical release for one day (along with the episode "Datalore") to celebrate the 25th anniversary of the series on July 23, 2012.

Kosinski and his assistant, an alien from Tau Alpha C who claims his name is unpronouncable and asks them to refer to him as Kosinski's Assistant. As Kosinski and the Assistant explain the tests to the engineering crew, Wesley Crusher (Wheaton) quickly grasps what the tests are designed to accomplish and the Assistant expresses admiration for his problem-solving abilities. The test quickly goes awry when the Enterprise speeds up, surpassing the
