ISS038-E-025016 (3 Jan. 2014) — NASA astronaut Rick Mastracchio, Expedition 38 flight engineer, conducts a session with the Capillary Flow Experiment (CFE-2) in the Harmony node of the International Space Station. 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.
