The Expedition 24 crew members were busy with a variety of science experiments and maintenance activities Wednesday as they orbited the Earth aboard the International Space Station.
In the Japanese Kibo module, Flight Engineer Doug Wheelock set up equipment in the Fluid Physics Experiment Facility for a study of the Marangoni effect, which is the flow of liquids caused by surface tension.
Flight Engineer Tracy Caldwell Dyson changed out hardware and removed samples from the Multi-user Droplet Combustion Apparatus, which is part of the Combustion Integrated Rack (CIR) in the U.S. Destiny laboratory. The CIR is an experiment facility that helps researchers study how different materials combust in the microgravity environment aboard the station and can be operated by crew members or remotely by researchers on Earth.
Flight Engineer Shannon Walker analyzed water samples from the station’s Water Recovery System.
