Reid Wiseman and Alexander Gerst spent much of the afternoon in the Quest airlock to configure tools and equipment for a pair of U.S. spacewalks set for October.

Wiseman and Gerst are slated to suit up for the first Expedition 41 spacewalk on Oct. 7, while newly-arrived astronaut Barry Wilmore will join Wiseman for the Oct. 15 excursion.

Among the tasks scheduled for the spacewalks will be the transfer of a previously uninstalled pump module from its temporary stowage location to the External Stowage Platform-2 and the replacement of a failed sequential shunt unit designed to regulate current from one of the station’s solar arrays.

A Russian spacewalk on Oct. 21 is also on the schedule.

Throughout the day, Wiseman participated in the Pro K study, as nutritionists monitor how dietary changes may affect the loss of bone density that occurs during long-duration spaceflight.

Wiseman has been following a prescribed diet and testing his urine samples to provide data for the researchers.

On Sunday, Wiseman and Gerst will once again review the procedures for grappling Dragon and conduct a final Canadarm2 robotics training session with the Robotics Onboard Trainer.

Over the weekend, all three crew members also will take care of weekly housekeeping chores and continue their daily 2.5-hour exercise sessions to stay fit.
