6:20 PM, 11/18/08, Update: Spacewalkers make progress cleaning, lubricating starboard SARJ

Despite losing a tool bag overboard while struggling to clean up a grease gun eruption, astronaut Heidemarie Stefanyshyn-Piper and fellow spacewalker Stephen Bowen made good progress cleaning and lubricating a damaged solar array rotary joint on the international space station.

Five hours into a planned six-and-a-half-hour spacewalker, the astronauts, sharing Bowen's tools, have made up lost time and presumably will complete the work originally planned for today's excursion, if not more.

Flight controllers at the Johnson Space Center, meanwhile, are assessing the impact of the lost tools, which included two grease guns, a scraper tool, a debris bag and a large trash bag.

The grease guns are being used to lay down beads of lubrication on the 10-foot-wide drive gear of the station's starboard alpha rotary joint after the bearing races have been cleaned. Bowen and Stefanyshyn-Piper, working on opposite sides of the drive gear, have had no major problems removing trundle bearings, cleaning and lubricating the bearing races.

The astronauts are running ahead of schedule despite the earlier problems.
