MOSCOW, June 30 (UPI) -- The crew of the International Space Station prepared Wednesday for a July 1 space walk to fix a gyroscope, Russian engineers said.
Sometime in the first hour or two of Thursday Russian cosmonaut Gennady Padalka and U.S. astronaut Michael E. Fincke will begin a six-hour session on the station's outer surface, Novosti reported.
Padalka and Fincke checked spacesuits July 28, subsequently relaxing July 29. On Wednesday the men checked but did not try on their spacesuits.
Experts also found out the cause of the first unsuccessful space walk that was to have taken place in the early hours of June 25. According to experts, Fincke didn't turn the injector handle completely, thus causing spacesuit pressure to drop sharply at the beginning of that space walk.
The injector is a built-in pump, which sends oxygen from the oxygen tank into the spacesuit itself.
