the procedures. The crew took some time out to gather in the Harmony module to speak with former President George H. W. Bush and his wife, Barbara, who were visiting Johnson Space Center. The rest of the day was devoted to assembling and configuring the new equipment and tools that would be required for the solar array repair, including a tool termed a "cufflink". The tear in the array is located at one of the hinges, which carries the load of the array, so the cufflink will be a load-bearing strap to relieve the pressure from the snagged area, transferring the load from the hinge, to the cufflink. The cufflink is made up of two wires, with two tabs at the end, that are threaded through existing reinforced aluminum holes in the solar array panels. The EVA plans call for the space station's robotic arm to grapple the shuttle's orbital inspection boom, with an extension on the end, to allow Parazynski to reach the solar array while positioned on a foot restraint at the end of the system. Wheelock will be watching to let the team know the clearances, and to assist Parazynski and the robotics team with positioning. With the changes to the timeline, the crew would be shifting their sleep schedule, to allow for a daylight landing on Wednesday, rather than the early morning landing that was originally planned. The fifth EVA that was planned for the Expedition 16 crew during the mission was delayed, and will be performed by the station crew after the shuttle departs. November 2 (Flight day 11) The shuttle and station crews spent the day discussing the new EVA plan with managers on the ground, reviewing the procedures, completing the tool configurations, and going over the timeline for the fourth EVA, scheduled for Saturday. The crew also positioned the station's mobile transporter and robotic arm on the end of the truss, to allow the apparatus to reach the solar array. Saturday's EVA would be the first operational use of the Orbiter Boom Sensor System (OBSS) to reach a worksite, although the task was tested and demonstrated during STS-121 to show the boom could provide a stable work platform for EVA activities. November 3 (Flight day 12) After being awakened by the theme music from Star Wars, the station and shuttle crews got to work preparing for the mission's fourth EVA. The spacewalk began
