Mission ULF-6's EVA-1 was completed successfully by EV1 Greg Chamitoff & EV2 Drew Feustel in 6h 19m, accomplishing all objectives. Beginning this morning at 3:10am EDT, the spacewalk ended at 9:29am. [EV1 & EV2 began their "campout" yesterday around noon in the U.S. Airlock (A/L) at ~12:51pm with hatch closure and depressurization of the Crewlock (CL) from 14.7 to 10.2 psi, followed by mask prebreathe (~12:51pm-1:36pm) and sleep from 2:26pm-10:26pm. After wake-up at nighttime and the usual hygiene break/with mask prebreathe for Taz & Drew at 11:01pm-12:11am, the A/L hatch was closed again by Ron Garan & Mark Kelly for EVA preps in 10.2 psi (12:11am-1:41am), followed by EMU purge (1:41am-1:56am) and prebreathe in the EMUs (1:56am-2:46am). Afterwards, with CL depressurization and EV1/EV2 switching to suit power, EVA-1 began at 3:10am. The excursion lasted 6h 19m.]
