Two episodes of Star Trek at once? Let’s party like it’s 1999. First up is “Rosetta,” in which Discovery goes to a mysterious planet and the landing party has some strong feelings. Then (at 20:46, for those who want to skip the “Discovery” talk) we cover the season premiere of “Star Trek: Picard,” which gets us really excited about starships, the Borg, and how wine bottles are designed in the early 25th century.
