Crew Completes Post-Spacewalk Duties

After the completion of a successful six-hour, 27-minute spacewalk Monday, the Expedition 25 crew members aboard the International Space Station worked on a variety of post-spacewalk activities and science experiments Tuesday.

Flight Engineers Fyodor Yurchikhin and Oleg Skripochka discussed their excursion outside the Pirs docking compartment with Russian spacewalk specialists. They also conducted post-spacewalk maintenance on their Orlan spacesuits, performing system checks, drying them and discharging their batteries.

Commander Doug Wheelock stowed U.S. spacewalking tools and equipment that were used during Monday’s spacewalk to prepare for the two spacewalks scheduled during the upcoming STS-133 mission.

Flight Engineer Shannon Walker set up hardware and equipment for a session of the Space Linear Acceleration Mass Measurement Device (SLAMMD). SLAMMD follows Newton's Second Law of Motion by having two springs generate a known force against a crew member mounted on an extension arm, the resulting acceleration being used to calculate the subject's mass, in effect weighing the individuals.
