[b]Third repair spacewalk set for Monday[/b]
After completing several days of analysis and refining procedures, space station managers met Sunday and gave final approval for a third spacewalk Monday to install a replacement ammonia pump as well as to restart and activate half of the station's cooling system that became inoperable two weeks ago.
The spacewalk, which will be the third aimed at bringing the station's cooling system back to full capability, is scheduled to begin at 5:55 a.m. CDT. NASA TV coverage will begin at 5 a.m. CDT.
To prepare for their planned 6.5 hour excursion, spacewalkers Doug Wheelock and Tracy Caldwell Dyson are spending Sunday night in the Quest airlock, "camping out" within a lower pressure atmosphere to purge the nitrogen from their bloodstreams as a means of avoiding the bends.
