Russian flight ground control center spokesman Valery Fallon said: "The International Space Station this week four (20) of the work is very busy. Astronaut must be completed for another spacewalk, the oxygen of electronic devices to do maintenance on a regular basis, There are a lot of other work. "

"Endeavor" crew Haidemali Stefan Nisihaining - Pieper and Shane Kim Brokaw on the same day the implementation of the tasks of the second spacewalk, space station repair solar panel rotary joint.

In the 18 completed the first spacewalk, the unexpected loss of Pieper kit to make her second spacewalk extra care.

"10 years have been hard to believe," Shayierman said, "this week is a four-day International Space Station."

Following the "dawn" for the space station, "foundation", the United States, Russia, Canada, Japan and European countries in the development and fabrication of the components within 10 years off one after another, the docking will be to build the International Space Station for the moment there are 3 bedrooms, a bathroom and A space in the kitchen of their homes.

Up to 20, the astronauts completed a total of 116 spacewalks, spending 725 hours to build the space station.

The space station "backbone" - aluminum truss is now extended to 89 meters in length, solar panels after the start area of 2675 square meters, covered basketball court 6. Space Station as a whole has already reached 313 tons.

Space station will cost a total of about 1,000 billion U.S. dollars.
