<\/a>Two Expedition 68<\/a> crew members are making final preparations before exiting the International Space Station<\/a> on Wednesday for the 12th<\/sup> spacewalk of the year. Meanwhile, the rest of the orbital residents kept up with advanced microgravity research operations.<\/p>\n Commander Sergey Prokopyev<\/a> will join Flight Engineer Dmitri Petelin<\/a> to begin a spacewalk at 9:20 p.m. EST on Wednesday. The duo will exit the Poisk module<\/a>\u2019s airlock and transfer a radiator from the Rassvet module<\/a> then connect it to the Nauka multipurpose laboratory module<\/a>.<\/p>\n The Roscosmos cosmonauts configured their Orlan spacesuits and reviewed their timeline today to prepare for the seven-hour spacewalk. Flight Engineer Anna Kikina<\/a> joined the pair for the spacewalk review. She will assist the spacewalkers on Wednesday as she operates the European robotic arm maneuvering the radiator from Rassvet to Nauka.<\/p>\n As the spacewalk preparations were ongoing, a variety of life science was under way aboard the orbital lab throughout Tuesday. NASA Flight Engineers Nicole Mann<\/a> and Josh Cassada<\/a> kicked off Tuesday collecting their blood samples for processing and analysis. Mann then moved on and took turns with NASA Flight Engineer Frank Rubio<\/a> nourishing biological samples for a study that explores how bones heal in space<\/a>.<\/p>\n Cassada also unloaded life support gear from inside the Cygnus space freighter<\/a> and activated the hardware inside the Quest airlock<\/a>. Rubio began his day connecting components inside the Combustion Integrated Rack<\/a>, a flames and fuels research device, before aiding Cassada with the Cygnus cargo transfers.<\/p>\n Astronaut Koichi Wakata<\/a> of the Japan Aerospace Exploration Agency (JAXA) spent Tuesday morning inside the Kibo laboratory module<\/a> servicing the NanoRacks External Platform<\/a> that places and exposes experiments to the vacuum of space outside the station. The veteran station resident wrapped up his day setting up the Liquid Behavior<\/a> investigation to study fluids in microgravity possibly advancing the design of space systems such as life support, vehicles, and fuel tanks.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0http:\/\/jscfeatures.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
