ISS MER Daily Report
STS 92/ISS 3A
GMT: 292:08:00 To GMT: 293:08:00
(3:00 a.m. 10-18-00 to 3:00 a.m. 10-19-00)
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
- 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.
- Audiotape of PMA APAS hatch opening indicated that a clunk noise was heard earlier than expected (fewer turns of the handle). Clunk is probably caused by hatch rollers disengaging from support bracket. S&M investigating the number of turns required for full travel and where disengagement normally occurs. Recent information received from Moscow indicates that "clunk" noise is expected to be heard anytime between 1 to 3 turn of the handle and that there is no concern. This issue is considered closed.
- 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 is dropping. IFI # 165 has been opened to further investigate this issue.
- Crew reported that one of the four RTAS bolts was not springy as expected. Inspection of the RTAS bolts during the EVA 4 showed that the bolts are nominal and there is no cause for concern.
- 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.
- Upon application of operating power to the S-Band Antenna Subassembly (SASA), Assembly Contingency Subsystem Radio Frequency Group (ACRFG) telemetry displays indicated PASS for POST /ECM and Environmental BIT summaries despite where fail indications are expected. IFI #0162 was generated to investigate the issue. C&T has verified that the RF input to the ACRFG was actually outside of the firmware Bit function limits of 8 dBm and +8 dBm. However, the software spec indicates that the RF input telemetry (A.K.A. Tx_Transmit_Cable_Power_Level) only be enable when the transmitter ON for 2 mS; otherwise, the RF input telemetry Bit Summary will report a PASS.
Last 24 Hours Status
- All EVA 4 activities were successfully performed.
- RTAS latch cycled
- Z1 FRGF was relocated
- Z1 tray was deployed
- MBM capture latch cycled.
- Work is continuing on FD9 Egress procedure and the configuration of the IMV valve and the MPEV caps prior to egress.
- Russians increased power allocation to 2000 W so that FGB batteries will be more loaded and wont pressure trip. PHALCON & THOR actively managing heaters to hold at about 1800 2000 W.
- Negative Power Balance indicated on SM display. Confirmed that MCC-M sent 5 commands via ECOMM. HSG reported that the SM internal cooling loop # 2, pumps 3 &4, and heaters were activated by MCC-M. Internal cooling loop will be in this configuration until DO2.
- The STAR team is working to ensure the ammonia accumulator doesnt over temp. There is a concern that the current attitude of the ISS may need to be changed before the crew is scheduled to awaken to keep the temperature below 38 deg C. .
- Node1 temperatures trending down. Average temperature is 24.5 Deg C.
