2493

2493 was the the year the UK-201, carrying Vicki and Bennett, left Earth. Vicki was ultimately bound for the planet Astra because her father had gotten a job there. (DW: "Desperate Measures")

Elsewhere, Don Arco moved to the Justicia system. (NSA: The Monsters Inside)

Behind the scenes
2493 is often cited as the year that The Rescue takes place, but neither episode actually confirms this. In fact, Vicki takes pains in "Desperate Measures" to point out that she's been on Dido for a "long time". The situation is confused more by statements in PDA: Byzantium!. See this examination of the question for more insight the problems of dating all things Vicki.
