Slosh testing of the Eurostar spacecraft is described. The spacecraft contains 1 ton of propellant on board, with a significant influence upon its dynamic characteristics. To define these, a series of drop tests was undertaken. The nutation time constant was the principal parameter of interest. The testing involved dynamical scaling, model fabrication, and all data capture and analysis. Initial tests indicate very short time constants and corrective action is necessary. This involved designing internal baffles to modify the fluid motion.
