Spacewalker Mike Foreman installed a set of cables along the Destiny laboratory for the station’s future space-to-ground antenna. He then swapped out a handrail on the Unity node with a bracket that will be used to route an ammonia cable to the Tranquility node when it arrives next year. Meanwhile Robert L. Satcher, Jr. lubricated the latching snares on the station’s mobile base system. The pair now is nearly two hours ahead of schedule.
