Space Station Live: The Science of Slosh.

NASA Commentator Amiko Kauderer talks with Jacob Roth, a co-principal investigator of the SPHERES Slosh experiment, which is investigating how fluids behave in weightlessness. Roth and his colleagues are making use of the SPHERES satellites, which were already on board the station for other science, to manipulate an instrumented container that records the movement of the fluid inside. The research is focused on improving our understanding of how propellants within rockets behave in order to improve the safety and efficiency of future fuel tank designs.
