Characters

 * Fourth Doctor
 * Frank Borman
 * William Anders
 * Jim Lovell

Continuity

 * The TARDIS is packed full of wrapped boxes. The Doctor notes that the downside to having a ship that dimensionally transcendental is that it's hard to clean. The Tenth Doctor would come to the same conclusion, after calculating that a simple cleaning session for the TARDIS would take more than six years. (COMIC: A Rose by Any Other Name)
 * The Doctor notes that while UNIT has a large collection of UNIT artefacts, they understand very few of them. A Zygon in the Black Archives would note the same fact in the 21st century. (TV: The Day of the Doctor)
