Astronauts at the International Space Station Monday conducted a spacewalk outside the station for the first time in half a year, the Associated Press reported. According to the AP, the spacewalk began late because of a leaky valve on the Russian side of the station. The crew reopened the air lock and checked the seals to ensure a tight fit before Russians Gennady Padalka and Yuri Malenchenko could go outside. The two spacewalkers will attach shields to protect against careening space waste, the AP said. The panels were supposed to go up during a February spacewalk, but it was put on hold. The men will also move a crane and release a small satellite.
