01:00 PM, 11/20/08, Update: Spacewalk begins

Running about 45 minutes ahead of schedule, astronauts Heidemarie Stefanyshyn-Piper and Robert "Shane" Kimbrough, floating in the space station's Quest airlock module, switched their spacesuits to internal battery power at 12:58 p.m. to officially begin a planned six-and-a-half-hour spacewalk.

The goals of today's excursion are to relocate two equipment carts on the front side of the station's solar power truss; to lubricate the capture snares in one end of the lab's robot arm; and to continue cleaning and lubricating the station's damaged right-side solar alpha rotary joint, or SARJ.

This is the 116th spacewalk devoted to station assembly and maintenance since construction began 10 years ago today. It is the 17th station spacewalk so far this year and the second of four planned for Endeavour's mission. Going into today's EVA, more than 80 astronauts and cosmonauts had logged 725 hours and 40 minutes of spacewalk construction time.
