STS 92/ISS 3A |
GMT: 293:08:00 To GMT: 294:08:00

OVERALL SYSTEM STATUS:
All ISS systems are in nominal flight/stage configuration with the exception of the following:
Previously Reported Status
- FGB Smoke Detectors 1, 3, 4, and 5 have been powered OFF.
- SM Smoke Detector 7 is failed.
- SM Solar Array #II portion of inboard panel segment not deployed.
- SM Batteries #4 and #5 are off line.
- The Orbiter Ku band has failed and the S-band is used to downlink the SWIS data through Ground
Stations.
- Docking was nominal, with the exception that no "close" indication of X4 connector was received. The only active function that passes through this connection is a 1553 Bus. Good mate has been confirmed via the functionality of the 1553 data bus, so the problem for this reading is on the Orbiter side of the interface. Further investigation of this issue will be done post mission.
- Loss of Orbiter Payload Cabin 3 bus took out Orbiter Space Vision System (OSVS), keel camera, and OIU 1. Backup SVS was recovered to support Z1 installation.
- Vacuum Access Jumper leak check failed the pressurization and leak test of the Z1 dome. Initial assessment is that leakage observed in the VAJ was due to temperature rebound after VAJ was isolated from space vacuum. Damaged O-ring also a possible suspect was replaced by the crew using one from the 35-foot VAJ. The 35-foot VAJ is now missing an O-ring; IFI 163 was opened regarding this issue and is expected to be close to PRACA.
- Crew was unable to completely seat one of the four ports ETSD bolts. Only three of four bolts are required for structural integrity. No impacts unless problem with bolt removal. It is suspected that the bolt did not seat due to insufficient torque applied.
- Crew was unable to hard dock Articulating Portable Foot Restrain (APFR) in WIF Z1-21 due to hard interference between WIF Flange and APFR Bolts. A thermal shield that was installed on the Load Limiter of the APFR appears to be the culprit. APFR was placed in WIF Z1-20 and boom deploy task was completed free float. Later Crew removed the thermal covers from APFR and IAPFR. APFR was installed in WIF 21 and IAPFR in WIF 4 during the EVA 3.
- Plasma Contactor Unit (PCU) #2 did not discharge pressure at a rate expected. PCU 2 has been power cycled and Latch Valve 2 has been closed and pressure has dropped to 4.1 PSI. IFI # 165 was opened and closed to PRACA 2292.
- During EVA 3 Crew had trouble mating P609/J609 connection. The crew Left P609 unmated with the thermal bootie covering it and wired tied to adjacent connector P608. P609 is not used until 5A.1 to provide APCU power to the MPLM via PMA2. IFI #164 has been opened to further investigate this issue. The IFI was closed to PRACA 2291.

Last 24 Hours Status
All EVA4 tasks were successfully completed.
Egress from ISS fell behind schedule for several minor stowage problems and a Node1 closeout panel (1F89465) failing to be re-installed. FGB has been egressed. Egress from the node will occur at approximately 8:00 am CDT. 10-20-00, with undocking occurring 1 orbit later. Undocking predicted at 10:09am CDT Friday.
The activation and checkout of all 4 CMGs was successfully completed.
Crew found the missing seal from the 35 ft VAJ. In summary the 5-ft VAJ had a damaged O-ring, which was replaced by one from one end of the 35-ft VAJ. The O-ring from the other end of the 35- VAJ was found floating by the crew. The damaged O-ring along with the one that crew found are being returned. Plans are to manifest two O-rings on 4A.
The FCT had the crew cap the Deck MPEV per the procedure, but the cap is to be removed prior to egress. The MPEV still meets 2 seals to vacuum safety requirement.
Crew unable to install closeout panel after Y-jumper installation. Panel currently stowed in front of the ECS pallet.
Safetys concerns regarding the FGB main engine prop valves withstanding transfer/storage pressures due to the non-firing of the FGB main engine Pyros were discussed during a telecon with the Russians. Representatives from KhSC/Prop and MER PROP specialist discussed the potential to expose the FGB main engines to higher pressures during the transfer. Based on a review of the schematic, the PROP team believed that the manifold motor isolation valves could back relieve and expose the main engines to the higher pressures. KhSC experts explained the design of the valve and believes that the schematic PROP has is incorrect. With the understanding that the valve is positioned incorrectly in the MER schematic, there is no concern with the planned transfer. KhSC requested a FAX stating our position on the performance of the transfer on Sunday. ISS MER Prop will follow up with this request Friday morning after verifying that our schematic indicates a wrong valve position. Propellant transfer will take place Sunday evening (Moscow time).
PCU 1 powered up to get a pressure reading. Tube pressure reading was approximately 1 PSI
N14B Y-Cable was installed. The NOD1P1-01 closeout panel (1F89465-1) could not be reinstalled during the N14B Y-Cable Installation. IFI #166 has been opened to investigate this issue.
Node Ingress temperature was 23C.
