Steve Swanson, US astronaut, on the ISS. Astronaut photograph of NASA astronaut Steve Swanson (born 1960), Expedition 40 commander, conducting a session with the Capillary Flow Experiment (CFE) in the Harmony node of the International Space Station (ISS). CFE is a suite of fluid physics experiments that investigate how fluids move up surfaces in microgravity. The results aim to improve current computer models that are used by designers of low gravity fluid systems and may improve fluid transfer systems for water on future spacecraft. Photographed on 3rd July 2014.
