These Are the Voyages...

"These Are the Voyages..." is the series finale of the American science fiction television series Star Trek: Enterprise. The 22nd episode of the fourth season and the 98th of the series overall, it first aired on UPN in the United States on May 13, 2005. It is a frame story in which the 22nd-century events of Star Trek: Enterprise are recounted in a 24th-century holodeck re-creation that is folded into the Star Trek: The Next Generation episode "The Pegasus", which aired eleven years earlier. It features guest stars Jonathan Frakes, Marina Sirtis and Jeffrey Combs, as well as a voice cameo from Brent Spiner. Series creators Rick Berman and Brannon Braga, who co-wrote the episode, conceived "These Are the Voyages..." as a valentine to Star Trek fans.

Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, the story moves to the year 2370, when Commander William Riker grapples with making a difficult admission to his commanding officer about a cover-up. Riker, after consulting Counselor Deanna Troi, turns to the simulated events of the year 2161 for guidance, when the crew of Enterprise travels home to Earth for both decommissioning and the formation of the United Federation of Planets.

Reaction to "These Are the Voyages..." was negative. Critics and cast alike believed the Next Generation frame robbed the characters and their fans of closure, and that the death of Commander Trip Tucker felt forced and unnecessary. The final episode attracted 3.8 million viewers, the highest number since the previous season. After a strong premiere, Enterprise had grappled with declining ratings throughout its run. By the fourth season, fewer than three million viewers tuned in each week despite what some fans and critics considered an increase in episode quality. After selling the syndication rights, Paramount announced in February 2005 that the fourth season would be the show's last. With no new Star Trek episodes in the fall of 2005, the 2005–2006 season was the first year without a first-run Star Trek in 18 years since 1987.
