Sloshsat FLEVO is a mini satellite for the study of liquid dynamics and liquid management problems in space. The behavior of water in an instrumented tank in the satellite will be monitored to help understand how sloshing affects the attitude and orbit control of space vehicles. The micro-gravity disturbance by liquid in a tank is determined as well. Of the total mass of 129 kg of Sloshsat FLEVO, 33.5 kg is liquid water in a smooth 87-Uter tank. Sloshsat FLEVO is to be launched from the Space Shuttle, and operated for two weeks from the ground via the Space Shuttle communication channels. The satellite is currently being completed. This paper describes mission objectives, project, all spacecraft subsystems, testing, operations, safety aspects, and status.
