International Space Station Daily Report
ISS On-Orbit Status 01/30/08 All ISS systems continue to function nominally, except those noted previously or below. Stage EVA-14 by CDR Peggy Whitson & FE-2 Dan Tani was completed successfully in 7hr 10min, accomplishing its objectives. During the spacewalk, Whitson (EV1) & Tani (EV2), supported by FE-1 Yuri Malenchenko as intravehicular (IV) crewmember, removed the failed Stbd (right-side) BMRMM (Bearing Motor Roll Ring Module) and replaced it with a new spare, followed by more investigation and photo documentation of the Stbd SARJ (Solar Alpha Rotary Joint). [The S4-1A BMRRM removal & replacement task was completed successfully. There was an S-band communication problem toward the beginning of the EVA that was cleared with a BSP (Baseband Signal Processor) power cycle. The communication dropout happened before the crew got into critical operations and was recovered in time to have very little effect on the overall EVA timeline. After the new BMRRM was installed all the power channels were reconfigured and the BGA was rotated and checked out successfully. Afterwards, the BGA was in autotrack and performing nominally. The removed BMRRM was brought back inside and will be stowed for return on the next available Shuttle flight. Per plan, there was time for the EVA crew to remove and inspect under several starboard SARJ covers. Eight of the remaining thirteen covers were inspected, leaving five more to be inspected on a later EVA. Photos taken during this activity are being downlinked for review by the SARJ troubleshooting team.] [Official start time of the spacewalk was 4:56am EST, 34 minutes ahead of the timeline, ending at 12:06pm. Total EVA duration (PET = Phase Elapsed Time) was 7h 10min. It was the 101st spacewalk for ISS assembly & maintenance and the 73rd from the station (28 from Shuttle, 51 from Quest, 22 from Pirs) totaling 443h 13min, and the 5th for Expedition 16 (totaling 35h 21min. During the spacewalk, her sixth, Peggy Whitson set a new record of aggregated EVA time by a woman of 39h 46min when she exceeded her previous mark of 32h 36m. After today's EVA, a total of 123 spacewalkers (92 NASA astronauts, 21 Russians, and ten astronauts representing Japan-1, Canada-4, France-1, Germany-1 and Sweden-3) have logged a total of 631h 35min outside the station on building, outfitting and servicing. It was also the 123rd spacewalk by U.S. astronauts.] Whitson and Tani began their overnight Campout prebreathe and lockout in the A/L at ~2:50pm EST. With METOX (Metal Oxide) canisters for CO2 removal in the A/L, the two spacewalkers will perform start PBA mask prebreathe for denitrogenation, while readying their equipment, then depress the A/L to 10.2 psi for the campout. 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.] 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 were also scheduled for their regular post-EVA PMCs (Private Medical Conferences) with the ground. No CEO (Crew Earth Observation) targets uplinked for today. CEO photography can be viewed and studied at the websites: ISS Orbit (as of this morning, 8:38am EST [= epoch]): Significant Events Ahead (all dates Eastern Standard, some changes possible.): |
