\u201cRegarding STS-400, Gerst expects folks to have completed their CoFR (Certification of Flight Readiness) for STS-400 as part of their STS-125 preparations. Don\u2019t expect to have an FRR for STS-400 unless it is called up. Plan would be to conduct this FRR at the L-2 (days) if needed.\u201d<\/p>\n

Several processing get-wells \u2013 such as the damaged radiator \u2013 are known and not expected to cause any issues with tracking the target launch date of the 11th, with the memo only updating an issue with the IMAX Cargo Bay Camera (ICBC), which is part of the Hubble payload.<\/p>\n
\u201cThe payload team is working some low level ICBC issues (ICBC aperture door). Have seen motor current spikes and door chattering and motor continued to run after door opened,\u201d added the memo.<\/p>\n
\u201cMotor and camera in general are located close to COS (Cosmic Origins Spectrograph) instrument and there is concern if it overheats it would contaminate the instrument.<\/p>\n
\u201cDid additional troubleshooting and believe it is a gravity affect and will go away in orbit. Ops working options to power off if needed. ICBC Camera lenses and iris openings. One of them doesn\u2019t open to the full open position, only goes to 85 percent. Only need 0.5 f-stop so no impact and will fly as is.\u201d<\/p>\n
STS-125 Processing Latest:<\/p>\n
Regular pad processing remains on the timeline for Atlantis, with closeouts of the vehicle taking place ahead of flight.<\/p>\n

\u201cHST SM-4 end-to-end testing was successfully completed Thursday Final EMU (EVA Mobility Units) stow and airlock closeouts were completed Thursday,\u201d noted end of week processing information on L2.<\/p>\n
\u201cFinal Ordnance installation (S5009) picked up yesterday and working through Friday. FSS (Fixed Service Structure) fuel scrubber liquor change out (in SCAPE) was completed last night during S5009. S1287 Orbiter Aft Closeouts continue throughout the week and conclude with the Aft Confidence test, planned for Monday.\u201d<\/p>\n
A couple of new IPRs (Interim Problem Reports) were noted on the processing information \u2013 one of which has already been closed, while the other is under investigation.<\/p>\n
\u201cNEW IPR: During open loop checks, system experienced multi-path RH (Right Hand) side \u201cB\u201d dropped below 1.0 VDC for 200 milliseconds. Reloaded codes and performed open loop test again,\u201d added the report.<\/p>\n
\u201cThe result was a successful test with data verifying the low voltage was caused by multi-pathing. Most probable cause was the configuration of the Right Hand SRB skirt platform not being extended. This IPR will be closed as an explained condition.<\/p>\n
\u201cNEW: Eastern Range holdfire circuit voltage is lower limits, should be NLT 32 volts. During hold fire checks the hold\/proceed signal from eastern range was not making it to the system. Troubleshooting to date is indicating the Range side is good. KSC Comm is continuing to investigate the issue on their end. Constraint S0007 (launch countdown).\u201d<\/p>\n

While IPRs are usually closed ahead of the time they become a constraint to the flow pressing forward, good news has already been confirmed on an investigation on both Atlantis and Endeavour, relating to a stud that was found to be broken on Discovery\u2019s FRCS F5R thruster.<\/p>\n
\u201cThis prompted us to check the other orbiters. Atlantis is good to go, I expect Endeavour to be good to go, but can not confirm that right now, we have not checked,\u201d noted Launch Director Mike Leinbach.<\/p>\n
\u201cForward RCS vernier thruster stud inspections (OV-103 issue) are complete with no anomalies,\u201d confirmed processing, with a late Friday update also confirming the investigation to the identical hardware on Endeavour had resulted in no negative observations.<\/p>\n
Even if a problem had been found, it would have likely resulted in a waiver, given Discovery had probably flow a couple of missions prior to the broken stud being found.<\/p>\n
Had problems been found on Discovery\u2019s sisters \u2013 with enough concern to require replacement hardware in that location \u2013 the call would have been to rollback, destack and remove of the FRCS in the Orbiter Processing Facility (OPF).<\/p>\n
Repairs on the damaged radiator on Atlantis will begin on Saturday, following the accident involving a liberated socket from a torque wrench, which impacted two areas \u2013 resulting in two cracks \u2013 on the thin aluminium face sheet, before bouncing off two engineers working at the pad, both of whom we\u2019re unhurt.<\/p>\n
\u201cCaused a couple dents. Starting to stage repair Friday, repair is due on Saturday, and we can go into Sunday if needed,\u201d added Mr Leinbach. \u201cThe impact did not damaged the freon tubes.\u201d<\/p>\n
\u201cRadiator repair for scheduled for Saturday; plan is to perform a standard repair, which involves complete removal of the damaged area and installing a plug and doubler,\u201d confirmed Friday processing information, which highlights the weekend work on Atlantis.<\/p>\n
\u201cWeekend work: Radiator repair, Aft IEA and left-hand forward skirt closeout, LOX\/LH2 dew point\/conditioning, Orbiter Boom Sensor System final stow, and Launch Countdown Preparation.\u201d<\/p>\n
