When Margo is looking at Brazil's launch platform on her laptop, the image is of real-life Alcântara Space Center in northeastern Brazil.
When Commander Poole insists that her future grandchild will watch Star Trek with her, she says they will watch "all three series." This indicates that of the five Trek shows that existed by 2003 in this timeline (the original Star Trek, Star Trek: The Next Generation, Star Trek: Deep Space 9, Star Trek: Voyager, and Star Trek: Enterprise), only the original series, plus the two on which For All Mankind creator Ronald D. Moore worked (The Next Generation and Deep Space 9) exist in the show's alternate timeline, and that the later less well-reviewed series were not created.
This episode takes place in October 2003.
