Last Glove Check


Peggy Whitson takes photos of the spacewalkers' gloves, which will later be closely examined by the ground team to check for damages incurred during the spacewalk.

Installing New Lithium-Ion Batteries


This diagram shows how the new lithium-ion batteries and adapter plates are configured with the old nickel-hydrogen batteries.

Before & After


This diagram shows the configuration of batteries and adapter plates before and after the spacewalk. Adapter plates were removed from the HTV-6 cargo craft and installed at the station's integrated electronics assembly (IEA) to complete the replacement of nickel-hydrogen batteries with lithium-ion batteries.

Mission Control


NASA's mission control in Houston monitored the spacewalk while helping to guide the astronauts through all their tasks.
