EVA-13 by CDR Peggy Whitson and FE-2 Dan Tani was completed successfully in 6h 56m, accomplishing its objectives. During the spacewalk, Tani (EV1) & Whitson (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, inspected the Stbd (right-side) 1A BGA (Beta Gimbal Assembly) and BMRMM (Bearing Motor Roll Ring Module), followed by a detailed investigation and photo documentation of the Stbd SARJ (Solar Alpha Rotary Joint). Found no obvious signs of external damage on cables or hardware of the BGA & BMRMM that might have caused the repeated tripping of circuit breakers (RPCs/Remote Power Controllers), making it more likely that the issue is internal to the hardware or its electrical system;
Prior to the spacewalk, FE-1 Malenchenko verified closure of the protective Lab window shutter. Malenchenko also completed the pre-egress reconfiguration of the Russian STTS (onboard telephone/telegraph subsystem) to its EVA settings. After the crew's return, Yuri reconfigured the STTS for nominal ops. (The "Voskhod-M" STTS enables telephone communications between the SM (Service Module), FGB, DC1 Docking Compartment and U.S. segment (USOS), and also with users on the ground over VHF channels selected by an operator at an SM comm panel, via STTS antennas on the SM's outside. There are six comm panels in the SM with pushbuttons for accessing any of three audio channels, plus an intercom channel. Other modes of the STTS include telegraphy (teletype), EVA voice, emergency alarms, Packet/Email, and TORU docking support.) During the spacewalk, Yuri provided IV support, prepared the DCS 760 camera setup for post-ingress photographing of the EVA gloves and subsequently assisted the spacewalkers in ingressing, CL (Crew Lock) repressurization and post-EVA activities. The FE-1 also performed the routine servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM (Service Module). (Regular daily SOZh maintenance consists among else of replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.) During Campout, after wakeup and before breakfast, FE-2 Dan Tani again accessed the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and completing questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for later downlink. (To monitor the crewmember's sleep/wake patterns and light exposure, Dan wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.) After returning on board from outside, Whitson and Tani doffed the EMUs, after taking photographs of the gloves and overgloves while still pressurized. As part of post-EVA tasks, the spacewalkers also reported on size fit of their EMUs and components. Later today, CDR Whitson will downlink the EVA imagery to the ground and reconfigure the DCS 760 for regular use (e.g., removing its thermal blanket). Afterwards, Peggy and Dan are also scheduled for their regular post-EVA PMCs (Private Medical Conferences) with the ground. CEO photo target uplinked for today was Khartoum, Sudan (Greater Khartoum (population 8.3 million, 2007 est.) includes Khartoum (2.2 million) in the acute angle between the Blue and White Niles, and Omdurman (3+ million) on the west side of the White Nile. Omdurman is the largest city in the Sudan and the fastest growing, partly because of refugees fleeing western Sudan. The growth of cities, especially in the Third Word, is best documented by remote means from the air or space. Looking a touch right for Khartoum and at nadir for Omdurman, shooting city margins).
