NASA Space Station On-Orbit Status 3 August 2005
SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by SpaceRef.com (copyright © 2005) to enhance access to related status reports and NASA activities.
All ISS systems continue to function nominally, except those noted previously or below. Flight Day 9 of the STS-114/LF-1 mission.
EVA-3 objectives successfully accomplished!
After crew wakeup at 11:40pm EDT last night, CDR Krikalev and FE/SO Phillips spent most of the day supporting the third spacewalk by Shuttle Mission Specialists Steve Robinson and Soichi Noguchi.
FE Phillips terminated the recharging of EVA batteries in the A/L BSA (battery stowage assembly) and brought the A/L crew lock (C/L) to pre-EVA configuration. [In preparation for EVA-3, the crew had reviewed objectives and timeline, configured and checked out tools required, and pre-positioned the SSRMS (Space Station Remote Manipulator System) for the spacewalk activities by relocating it from the Lab PDGF (Power & Data Grapple Fixture) to the MBS (Mobile Base System) PDGF.]

The FE also performed the periodic checkout of the Airlock s RSP (Respiratory Support Pack), #1002. [The RSP is designed to breathe for an incapacitated crewmember in the event of a respiratory health event on board ISS.]
Before the EVA, Sergei took the ARISS (amateur radio ISS) Sputnik-SM Kenwood D700 ham radio station in the SM out of repeater mode and set it to packet mode, to prevent possible frequency conflicts with the MISSE 5 materials payload.
The EVA began at 4:48am, about 38 min later than planned. The spacewalkers, again egressing from the Shuttle airlock and keeping the ISS A/L C/L compartment as backup point of ingress, successfully accomplished all main objectives. These were: installation of the large ESP-2 (External Stowage Platform 2) at the Quest A/L, including its electrical power-up, removal & return of ESP-2’s grapple fixture, installation of the external materials exposure experiment MISSE 5 on the P6 truss, enabling of a subsequent robotic survey of thermal protection samples in the payload bay (by opening the lid covering the samples), and the much-publicized removal of two protruding felt-strips used as glued-in fillers between tiles. Other ISS related tasks included inspection of solar BGA (beta gimbal assembly) restraint bolts and photography of the FPP (floating potential probe). Installation of the ISS truss-mounted camera has been deleted from this EVA to accommodate the addition of the gap filler tasks, and the get-ahead task of removal & return of the failed ISS thermal RJMC (radiator roll joint motor controller) was deferred to a later EVA. [After being flown to the Orbiter underbelly worksites by MS Wendy Lawrence and PLT Jim Vegas Kelly skillfully operating the SSRMS (Space Station Remote Manipulator System), EV2 Steve Robinson easily removed both tile gap fillers by gloved hand. The RJMC will be retrieved in time for ground failure analysis prior to new unit delivery/replacement on the 12A mission in early 2006.]
After EV1/EV2 egress, the Shuttle airlock was repressurized to 14.7 psi and used as a corridor for internal cargo transfers throughout the EVA to maximize overall mission productivity. It was depressed again at the end of the spacewalk for hatch opening, followed by crew ingress and repressurization to 14.7 psi.
The spacewalk ended at 10:49am, for a total duration of 6h 1m. It was the 61st EVA devoted to ISS assembly operations and the 28th from the Shuttle (33 from the ISS A/L and Pirs DC-1), giving 53 astronauts and cosmonauts a cumulative total of 368h 20m of station spacewalk time.
At EVA termination, Phillips checked the C/L for leaks during its repressurization and later returned its interior to post-EVA configuration.
CDR Krikalev took readings from the newly installed GANK-4M gas analyzer in the Service Module (SM), where he had recently (7/27) adjusted a coefficient setting in the CO (carbon monoxide) sensor.
Both ISS crewmembers continued cargo transfers between the station and MPLM Raffaello , including EVA equipment from the Shuttle and ISS airlocks for return to Earth.
In the Lab, John Phillips removed and replaced six HEPA (high-efficiency particulate air) bacteria filters. [Three of the old filters will be returned to Earth on LF-1 for engineering analysis. The other three were stowed for eventual disposal on Progress.]
Sergei completed the daily routine maintenance of the SM’s SOZh environment control & life support system, including its toilet system (ASU) and the weekly inspection of the BRPK air/liquid condensate separator apparatus.
Both crewmembers conducted their regular 2.5-hr. physical exercise program on the CEVIS cycle ergometer, TVIS treadmill, RED resistive machine and VELO bike with bungee cord load trainer. [Sergei s daily protocol prescribes a strict four-day microcycle exercise with 1.5 hr on the treadmill and one hour on VELO plus load trainer (today: Day 4 of a new set).]
Sleep period begins this afternoon at 3:10pm EDT for all nine crewmembers again. Wakeup will be tonight at 11:40pm.
CMG-1 (control moment gyroscope #1) spinup was completed successfully, and the newly installed gyro was added to the US attitude steering law yesterday at ~4:54am. [The ISS is now back on three-CMG attitude control. After LF-1, CMG-3 will be added, restoring full four-gyro control for the station.]
With the extra flight day added, Shuttle/ISS undock time will be on FD12 (Saturday, August 6) at 3:22 am EDT, for a landing at KSC on FD14 (Monday, August 8), with deorbit burn at 3:35am and touchdown at 4:37am EDT).
