Abstract A key objective of cryogenic fluid management of the spacecraft propulsion system is to develop the technology necessary for acquisition or positioning of liquid and vapor within a tank in reduced gravity to enable liquid outflow or vapor venting. Resettlement or reorientation of liquid propellant can be accomplished by providing the optimal impulsive acceleration to the spacecraft such that the propellant is reoriented over the tank outlet. Characteristics of slosh waves of various frequencies excited by the resettling flow field are discussed. Slosh wave excitations shift the fluid mass distribution in the container which impose time dependent variations in spacecraft moment of inertia. This information is important for spacecraft control during the course of liquid reorientation.
