began for the astronauts at 15:19 UTC. The day's primary activity, EVA No. 2, began rewiring work to bring the station's permanent electrical power systems into use. To allow this changeover, station controllers had to power down about half the systems on the ISS. The EVA started at 19:41 UTC with Bob Curbeam and Christer Fuglesang exiting the Quest airlock, 30 minutes early. EVA No. 2 was planned to activate channels 2 and 3 of the four-channel electrical system, and the work progressed smoothly. About two hours into the spacewalk the first current was flowing through the reconfigured system, using the power from the P4 solar arrays for the first time. The EVA was completed in exactly 5 hours, finishing at 00:41 UTC. December 15 (Flight day 7) Flight day 7 was a light work day for the crews of Discovery and the ISS after the previous days' activities. Spacewalkers Bob Curbeam and Christer Fuglesang enjoyed some R&R, while the rest of the crew performed cleanup and preparatory tasks for Flight day 8's planned EVA #3. The traditional joint photo session and joint news conference were held by the crews. During this event Swedish first time astronaut Christer Fuglesang was interviewed by Crown Princess Victoria and also set a 20-second Frisbee world record in space, broadcast live on Swedish TV4. In an attempt to free a stuck solar panel, Thomas Reiter exercised vigorously on a machine which is known to cause oscillations in the solar arrays; it was not successful. Mission controllers continued to look at other solutions to the solar panel folding problem so as to enable complete retraction, including an extended or additional EVA. December 16 (Flight day 8 – EVA #3) Flight day 8 began for the astronauts at 14:48 UTC. Astronauts Bob Curbeam and 'Suni' Williams completed the rewiring work on the International Space Station. The EVA began at 19:25 UTC and proceeded normally. As an "add-on task" to the EVA, astronauts Curbeam and Williams also continued work on the retraction of a sticking solar array, enabling the retraction of another six sections of the P6 array. At the end of the EVA there were another 11 "bays", or 35% left to retract. Upon completion of the EVA, the astronauts returned to the ISS via the Quest airlock. Another significant event during the EVA was the loss of 'Suni' Williams' digital camera. At the post-EVA press
