European Space Agency astronaut Alexander Gerst conducts a session with the Capillary Flow Experiment in the Harmony node of the International Space Station June 19, 2014 in Earth Orbit. The CFE is a suite of fluid physics experiments that investigate how fluids behave in microgravity which could benefit water and fuel delivery systems on future spacecraft. Scientists designed the CFE-2 to study properties of fluids and bubbles inside containers with a specific 3-D geometry.
