At the end of the second season of Star Trek: Discovery, the ship was left in the far future (the year 3188). This choice seemed to be a way of addressing the show’s continuity problems: it featured far more advanced technology than its original period should have, and it left questions about why Sarek and Spock hadn’t mentioned Discovery‘s Michael Burnham. The second-season finale attempted to address these concerns, and displacing the ship into the far future, beyond anything seen previously, could avoid future conflicts.
The 13-episode third season, set in 3188, debuted in October 2020. A fourth season is slated to debut in November 2021.
