25 DAY IN THE LIFE: LIVING AND WORKING IN SPACE AND ON THE GROUND CHAPTER 2 Figure 4. Expedition 7 (July 8, 2003) Science Officer Ed Lu exercises on a Cycle Ergometer Vibration Isolation System in the US Laboratory. Each crew member is scheduled for two exercise sessions per day. The workday never really ends for the flight control teams. Most of the teams—Houston, Huntsville, Munich, Tsukuba—split the day into three shifts of 9 hours, with an hour of overlap for the teams to hand over. In Moscow, the flight control team works a full 24-hour shift, handing over just before morning DPC, at the start of the workday in Moscow. The flight control teams on console are responsible for putting together the detailed timelines for the upcoming 7 days based on ISS Program requirements and direction from the increment flight control team. As discussed above, before the end of each crew workday, the ground teams will review and discuss any major changes for the next day’s timeline so that the crew can be informed as to what will be discussed during the evening DPC. The team may make additional changes while the crew sleeps, or may simply “fill in the blanks” by attaching procedures and messages to provide all the detail the crew and flight control teams will need to execute the timeline. The console team also typically reviews and updates the “3-day-out” and “7-day-out” timelines each day, so that they are continually looking ahead a few days to make sure all the details needed to complete each day’s objectives are captured in the plan. A standard process described in Chapter 1, with milestones throughout each 24-hour day and 7-day week, allows all of the control teams a chance to make inputs to each plan review before the final timeline approved and put on board for execution. The detailed plan for the day might not be finalized until a few hours before the crew awakens, even if the major objectives for that day were selected weeks, or even months, ahead of time. The increment lead flight controllers continue to hold JOPs as well, now focusing on assuring all details needed to support planned operations are ready to go, including the procedures, flight rules, analysis, and any associated agreements with international partners or
