A new task added to Wednesday’s spacewalk sent the shuttle crew to bed 30 minutes early on Tuesday. The second spacewalk will also start earlier at 7:15 a.m. EDT.
Spacewalkers Michael Good and Steve Bowen will relieve a snagged cable that is preventing full use of the laser imager and video camera. The equipment is located on the Orbiter Boom Sensor System.
Good and Bowen are "camping out" in the Quest airlock overnight at a reduced air pressure to purge nitrogen from their circulatory systems. This reduces the likelihood of developing the bends during spacewalk activities.
