Captain Adelaide Brooke is the famed commander of Bowie Base One, the first human colony on Mars, famous for mysteriously exploding. Orphaned during the Dalek attacks (the events of “The Stolen Earth”/“Journey’s End”), Adelaide grew up fascinated with space after staring into the eyestalk of a Dalek hovering outside her window who flew back to base and left her alive, rather than killing her as by all accounts, it should have. She dedicated her life to science and exploration, though she also had a family- a daughter and eventually, a granddaughter. When the Doctor stumbles upon Adelaide and her crew, he knows their death will galvanize the planet, particularly Adelaide’s granddaughter, and push the human race out to the stars, making the events on Mars a fixed point in time. Adelaide has a degree in mathematics as well as a doctorate in physics and she has extensive training as an astronaut, having worked for NASA before starting her work at Bowie Base One.
