plan, Discovery would undock on November 5, 2007, with a landing on November 7, 2007, at approximately 05:11 EST. October 30 (Flight day 8) The two crews spent the morning preparing for the mission's third EVA, which began at 08:45 UTC. The EVA completed the installation of the P6 solar arrays onto the P5 truss, and the rest of the EVA activities were accomplished successfully, with the EVA ending at 15:53 UTC. Once the P6 solar array was attached, the process of deploying the arrays began. The first set of arrays, 2B, was successfully deployed with no issues, but during the deployment of the 4B array, the crew halted when they noticed an abnormality. Initial images taken by the crew and station cameras showed what appeared to be a tear in a small portion of the array. During a press briefing, ISS Program Manager Mike Suffredini said the crew took high resolution images of the solar array, and the managers would analyze the images overnight to determine a course of action. Sufredini mentioned that with the array in the 90% unfurled position, it was still generating 97% of the expected power to the station, only slightly less than a fully unfurled array. October 31 (Flight day 9) The crew began the day working through a variety of tasks, including preparing for the fourth EVA, installing a Zero Gravity Stowage Rack in Harmony, and working with some of the experiments on board. Nespoli and Melroy participated in a Public Affairs event (PAO), and received a call from the President of Italy, Giorgio Napolitano. The entire crew took part in a second PAO event, fielding calls from news agencies from the United States, Europe, and Russia. Around 15:00 UTC, mission control informed the crew that Thursday's planned EVA would be postponed to either Friday, or perhaps Saturday, to allow for a new EVA plan to be worked out, which would include troubleshooting of the P6 solar arrays. November 1 (Flight day 10) Shortly after awakening in the morning, the crew was informed that the managers had chosen to take an extra day to evaluate and plan the fourth EVA. Managers initially planned for the EVA to be done on flight day 11, but would use an extra day to conduct further analysis and allow the crew to have extra time to make the tools and equipment needed, and to review and practice
