Dian's specialty is in the propellants field. The shuttle burns liquid oxygen and liquid hydrogen in its main engines, and uses nitrogen tetroxide and hydrazine in the engines it uses to maneuver while in orbit. Dian was appointed to the Air Force Academy the year before the military academies admitted women for the first time, and by serving as a role model, was instrumental in her Congressman's efforts to get women accepted into the academies. Dian is not married and has no children, although she has taken in foster children. When not behind a desk or in front of a computer, Dian can be found scuba diving, reading and writing science fiction, giving speeches as a Toastmaster, or being involved in politics to promote equal opportunities and rights.
Every obstacle yields to stern resolve.
He who is fixed to a star does not change his mind.
