Russian cosmonaut Vladimir Dezhurov and US astronaut Frank Culbertson, who commands the third regular ISS (International Space Station) expedition, have successfully completed their space walk. According to the mission-control center, both men, who are now busy drying their space suits, will relax later on. Experts are quite happy about their performance because Dezhurov and Culbertson have installed a Kurs radar antenna, which will enable cargo ferries and manned spacecraft to dock with the ISS's Russian-owned Pirs (Pier) mooring port. The two men laid cables, subsequently connecting the antenna with the Kurs system's equipment. After that, Dezhurov and Culbertson tested a boom near the Pirs mooring port, also filming and photographing the station's new solar batteries. According to mission controllers, one solar-battery section failed to unfurl; consequently, experts will be able to open it with the help of the afore-said video footage and photos. Dezhurov and Culbertson asked mission controllers for permission to try and open that solar-battery panel. However, they were not allowed to do this. The next expedition is going to accomplish this objective, mission-control center people noted. One unopened solar-battery panel doesn't affect onboard power supply a great deal, mission controllers noted. The third crew member, Russian cosmonaut Mikhail Tyurin, kept an eye on his colleagues during their EVA (Extra-Vehicular Activity), also providing them with some helpful tips. This is the expedition's last space walk, mission-control center officials stressed, adding that the three men will be replaced early this December.
