One set of Expedition 40 crew members is working advanced microgravity science while another set is wrapping up its stay in space.

NASA astronaut Reid Wiseman started his morning on a pair of fluid physics experiments. He first photographed samples of colloids, or microscopic particles suspended in liquids, for a version of the Binary Colloid Alloy Test experiment subtitled Low Gravity Phase Kinetics-Critical Point (BCAT-KP-1). Results may contribute to more advanced consumer products with unique properties and longer shelf lives...
