Occasionally one reads about a spacecraft "dumping fuel". It may mean expelling the propellant(s) as a liquid, or depleting them by burning them up. Although usually only fuel is mentioned, often the oxidizer is also eliminated at the same time. In any case, the propellants are eliminated from the spacecraft.
How does one do this without affecting the attitude or trajectory of the spacecraft?
