Following a busy day of robotics, the Expedition 26 crew members returned their focus Tuesday to activities inside the International Space Station as they performed science and maintenance tasks and made additional preparations for a Russian spacewalk.

Flight Engineers Dmitry Kondratyev and Oleg Skripochka held a timeline review tag up with Russian spacewalk specialists in advance of their Feb. 16 spacewalk out of the Pirs docking compartment. During their spacewalk, the two cosmonauts will install equipment for enhanced communications from the Russian segment of the station, remove debris panels and deploy a small satellite carrying congratulatory messages celebrating the 50th anniversary of Yuri Gagarin’s flight as the first human in space.

Meanwhile, Flight Engineer Alexander Kaleri loaded trash and other unneeded items into the ISS Progress 39 cargo vehicle for disposal when the craft undocks Feb. 20 and is sent to a destructive re-entry in the Earth’s atmosphere.

Commander Scott Kelly spent part of his day configuring the Combustion Integrated Rack, a facility that houses hardware capable of performing combustion experiments in microgravity. The station commander replaced a manifold bottle and unstowed items for upcoming activities with the facility.

Flight Engineer Paolo Nespoli spent much of his day unloading cargo from the second H-II Transfer Vehicle that arrived at the orbiting complex Jan. 27. Later he gathered U.S. tools to support the Russian spacewalk.

In the Japanese Kibo module, Flight Engineer Cady Coleman worked with the Binary Colloidal Alloy Test hardware for an ongoing investigation of polymer and colloidal particles. Results of this study will help scientists develop fundamental physics concepts previously cloaked by the effects of gravity.

Coleman also spent some time collecting test samples from the recirculating water loops of the Oxygen Generation System. Kelly teamed up with Coleman to analyze the water samples with a fluid conductivity meter.

The station’s residents also had several opportunities for Earth observation and photography as they soared 220 miles above the planet. Among the sites suggested by researchers for photography was the tallest mountain in Africa, Mt. Kilimanjaro in Tanzania. Scientists are particularly interested in documenting the condition of the small glaciers located at the summit, which have been receding dramatically.

The launch with crew successfully exchange the wreck,maintan increased communicative skills with explored space walk.
