The Surprising Absence of Medieval and 1950s-Style Time Travel Episodes in Star Trek Series

Throughout the extensive run of the Star Trek franchise, time travel has been a recurring theme, but it often took a unique turn across different series. A curious observation is the scarcity of time travel episodes that explore medieval European or 1950s New York settings. In fact, prior to the late 24th century settings in Voyager and Enterprise, there were a mere two notable exceptions in Deep Space Nine.

Time Travel in the Original Series and TOS Episodes

The first example of this type of time travel can be found in the original series, specifically in the two-part episode "Turnabouts," where the starship Defiant is transported through a time crack. During this journey, Benjamin Sisko, Jadzia Dax, and Julian Bashir find themselves in the late 21st century, encountering a society that is reminiscent of a dystopian future with people confined to ghettos. It is worth noting that this episode, like many TOS episodes, included elements salvaged from other series due to budget constraints, showcasing the studio's eagerness to maximize resources.

The second TOS episode that delves into this theme is "Tomorrow is Yesterday," where the crew finds themselves in a past where they encounter the original Enterprise once again, setting the stage for a classic adventure. These episodes, while flawed in their historical accuracy, represented an early attempt to explore the concept of time travel within the series.

Time Travel in The Next Generation and Treasure Hunts

While the original series had a few attempts, the transition to The Next Generation brought about a significant change in the storytelling approach. TNG had a substantial budget increase, which allowed for more elaborate and diverse storylines. As a result, fewer episodes focused on time travel to the past, opting instead for other narrative arcs. However, the series did not entirely ignore the concept; notable episodes include "Cause and Effect," "Time's Arrow," and "Tapestry."

Interestingly, TNG opted more frequently to simulate past environments using the Holodeck rather than actual temporal travel. This approach offered a controlled and more plausible environment for the crew to interact with historical figures and events, providing a semblance of time travel within the constraints of the show's universe.

Time Travel in Deep Space Nine and Beyond

The series Deep Space Nine (DS9) introduced a variety of time travel episodes that again focused on distant futures, with few exceptions. Notable examples include "Past Tense" where Sisko and Dax return to a recreated 20th century Earth, and "Little Green Men" where events from Forest of the Deep are reenacted. It is intriguing to note that these episodes often used existing technology and sets to create a sense of the past, highlighting the production team's creativity in tackling time travel narratives.

Voyager and Enterprise both embraced the concept of time travel more directly, with longer episodes that explored different time periods. In Voyager, for instance, the episode "Future’s End" offered a vivid depiction of the 1990s, which was far more contemporary to the series' airdate in the early 2000s, making the time travel concept more relatable and engaging for viewers.

Cost Considerations in Time Travel Episodes

A potential explanation for the limited number of time travel episodes focusing on more recent or medieval settings is the production costs. Episodes set in the distant past or medieval times require more extensive set design and wardrobe, raising production costs. On the other hand, episodes set in the 1990s or earlier can often leverage existing sets and costumes, making them more cost-effective. This economic factor might have contributed to the relatively sparse number of past-time travel episodes in later series.

In conclusion, while time travel in Star Trek has been a hallmark of the franchise, the choice of setting for such stories has varied throughout the years. The budgetary constraints of the original series and subsequent preferences for more sophisticated storytelling might have influenced the frequency of these episodes. The franchise's enduring legacy remains a testament to its ability to continuously innovate and captivate audiences with its compelling narratives.
