CHAPTER 2 DAY IN THE LIFE: LIVING AND WORKING IN SPACE AND ON THE GROUND 26 commercial providers (Figure 5). It may take quite a bit of coordination and detailed development work to put the procedures and supporting material together as well as testing or simulating the process before a specific operation. The JOP coordinates that work, and the individual lead flight controllers spend most of their days building those detailed products for final review and approval before they get attached to the appropriate plan. Although many activities have become routine, the dynamic and evolving nature of the ISS necessitates the continuous development or modification of many procedures. Figure 5. The Increment 40 JOP, working in Mission Control Center Houston, reviews current and future activities, and coordinates all the key elements between the engineering and science teams as well as the international partners.

Increment 44 Lead Flight Director Mike Lammers (sitting) discusses crew activities with fellow Russian Flight Director Alexei Buchilin (far right) and his interpreter Paul Kharmats. The Russian Space Agency houses several of its team members as part of the Moscow Support Group in Houston, while a number of NASA flight controllers work in Moscow as part of the Houston Support Group. See also the Introduction. The increment team, meanwhile, is looking out at the weeks ahead, and working to find homes for all the activities that the ISS partnership has agreed are priorities for this mission. This is an ongoing process. The increment manager, representatives of the ISS Program office that ensure the right activities are being performed, and their team in the Increment Management Center regularly review the Increment Requirements Definition Document (see Chapter 1). Those priorities are allocated to different stages in the increment via the Current Stage Requirements Document, which breaks down the 6-month Increment Requirements Definition Document period into the stages defined between major mission events—
