8:00 PM, 11/22/08, Update: Spacewalk ends

Astronauts Heidemarie Stefanyshyn-Piper and Stephen Bowen closed out a grueling six-hour 57-minute spacewalk at 7:58 p.m. today, repressurizing the space station's Quest airlock module. Five of six bearing assemblies wee replaced on the station's right-side solar array rotary joint and the sixth will be installed during a final EVA Monday.

This was the 117th spacewalk devoted to station assembly and maintenance since construction began in 1998 and the third of four for the shuttle Endeavour's crew. Total station assembly spacewalk time now stands at 739 hours and 23 minutes while the Endeavour crew's total climbs to 20 hours and 34 minutes.

This was the third EVA in a row for Stefanyshyn-Piper and the fifth of her career. With today's excursion, her personal EVA total stands at 33 hours and 42 minutes, moving her up to No. 25 on the list of most experienced spacewalkers.

"Let me just congratulate both of you," shuttle commander Christopher Ferguson radioed from the other side of the airlock hatch. "For what could possibly be Heide's last EVA, I knew Steve was going to have to push her in the airlock but I didn't know it was going to happen until you both got in! So welcome back both of you, great job."
