Commander Peggy Whitson and Flight Engineer Yuri Malenchenko completed their increment's first spacewalk Friday at 10:49 a.m. EST. Their 6-hour, 55-minute spacewalk began just over an hour early at 3:54 a.m.

The two spent early Friday morning disconnecting and stowing cables, removing a light on one of the station's transport carts and taking a cover off the Harmony node's Common Berthing Mechanism, or CBM. On Monday, the Pressurized Mating Adapter 2 (PMA-2) will be moved from the Destiny lab and attached to Harmony's CBM.

The spacewalkers also removed a base-band signal processor that will later be refurbished and a remote power controller module that will be replaced. They then transferred tools in preparation for upcoming spacewalks.
