Astronauts to Open New Room

They plan to install spacewalking handrails and other equipment to the outside of Harmony. The spacewalkers also will take a look at a rotary joint for the space station's solar wings that has exhibited electrical current spikes in the past 16 1/27 months. The joint is necessary for turning the solar wings toward the sun.

More computer repairs are also on the crew's Saturday to-do list. Both Discovery and the space station have had some networking problems over the past few days.
