\u201cLeft OMS Pod Lower Fuel Tank Temp: After going to B heaters, increased to near the SM limit of 95 deg F. Prop sent up a TMBU (Table Maintenance Block Uplink) as a precaution. OMS\/RCS are watching the issue but are not concerned. Similar signatures observed on STS-115, 117.\u201d<\/p>\n

The full overview of Atlantis\u2019 TPS will be collated over the next 24 hours, due to the complexity of the DAT tools for outlining any ROI (Region Of Interest) which can number in the hundreds.<\/p>\n
However, the key communication of Flight Day 10 came via DAT engineers noting no ROIs are deemed as a problem for the orbiter\u2019s safe re-entry \u2013 which was noted to the Orbiter Project Office (OPO) and the MMT midway through Wednesday.<\/p>\n
\u201cThe MMT continues to meet daily with no significant issues being worked; the mission continues to proceed as scheduled,\u201d outlined the MMT on the morning of FD10. \u201cAll level 1 LDRI (Laser Dynamic Range Imager) and IDC (Digital Camera) imagery has been review and there are no concerns, level 2 screening is continuing. Next status will be reported at the FD10 OPO tag today.\u201d<\/p>\n
It was during the OPO tag up meeting later in the day that the DAT confirmation came through, passing the orbiter\u2019s TPS as acceptable for re-entry.<\/p>\n
When and where Atlantis lands remains questionable, with three opportunities available for landing at the Kennedy Space Center (KSC) on Friday, before Edwards Air Force Base (Dryden) and White Sands are called up as additional options on Saturday, should KSC\u2019s weather remain doubtful on the outlook.<\/p>\n
\u201cThere will be three landing opportunities at KSC on Friday at 1004L, 1141L, and 1319L. KSC will be the only landing site brought up for Friday,\u201d confirmed the MMT. \u201cEdwards, White Sands, and KSC will be available for Saturday landing opportunities, if required.\u201d<\/p>\n
The weather for a KSC landing on Friday remains questionable, though a series of powerdowns have been conducted to preserve consumables, allowing for the mission to continue through to EOM+3 (End Of Mission, plus three days), if required.<\/p>\n
Endeavour, STS-400\/127 Status:<\/p>\n
Despite the clearance for entry, Endeavour will \u2013 as previously reported \u2013 remain on STS-400 standby, holding in the countdown prior to PRSD (Power Reactant Storage and Distributation) loading.<\/p>\n
\u201cSTS-400 Late LON S0007 Launch Countdown: CTS (Call To Stations) occurred at 0540L this morning,\u201d noted Wednesday processing information (L2). \u201cFD9 late inspection will drive MMT go\/no-go direction for PRSD load. The inspection results are expected sometime this afternoon or evening.<\/p>\n
\u201cA no-go decision (as is now officially the status) will result in a 24-hour hold in S0007, and the launch team will remain in a LON posture until completion of the de-orbit burn.<\/p>\n
\u201cIf landing is waived off on Friday, the 24-hour holds will continue until the de-orbit burn has been completed. S0024 Hyper QD (Quick Disconnect) de-mates will be performed in S0007 post-PRSD load.\u201d<\/p>\n
Once stood down from STS-400 requirements, Endeavour\u2019s role will official move to her primary STS-127 mission to the International Space Station (ISS) next month. The expected date for her rollaround to Pad 39A is pending the completion of repairs on Pad 39A, after STS-125\u2019s launch damaged part of the SRB flame deflector and associated Mobile Launch Platform (MLP) hardware.<\/p>\n
\u201cWork to repair the SRB flame deflector continues. Pneumatic line welding is complete. NDE and cleaning are in work,\u201d added Endeavour\u2019s processing status, with the poor local weather affecting elements of STS-127\u2019s preparations. \u201cS0600 Payload Ops: STS-127 payload delivery was rescheduled due to unacceptable weather and will be attempted again tonight.\u201d<\/p>\n

Sandbags and plastic tarping were used on Pad 39B, following a leakage of rain water at the base of camera mounts on the MLP raised deck.<\/p>\n\u201cThe water has run under the raised deck to a deck hatch under the raised deck,\u201d noted another report on Wednesday. \u201cWater leaked through this hatch onto a fire alarm panel.\u201d<\/p>\n
Another hazard for Endeavour is lightning, although she is ably protected by the three giant towers that were completed for the Ares I flights from Pad 39B. However, strikes close to the pad require the testing of the shuttle systems, to check for potential electronic inference.<\/p>\n
\u201cA possible lightning event was detected Monday afternoon about 0.33 nautical miles from Pad B. S0018.100 lightning data collection and analysis is in work. ERB (Engineering Review Board) determined there was no event that would cause further testing.<\/p>\n
\u201cSevere weather continues to be a concern. Last night at 0012L, a tornado warning was issued for KSC. No damage was reported, and the warning expired at 0030L. Also detected possible lightning strikes close to the Pad A perimeter. Data collection and analysis is in work.\u201d<\/p>\n
Behind the scenes, preparations for STS-127 are proceeding normally, with the MOD Flight Readiness Review (FRR) already complete (13 presentations on L2).<\/p>\n
The STS-125 IFA (In Flight Anomaly) review \u2013 and its resulting findings for the SSP (Space Shuttle Program) FRR for STS-127 \u2013 is currently being collated by orbiter departments.<\/p>\n

The DAT (Damage Assessment Team) have completed the review of Atlantis\u2019 Flight Day 9 Thermal Protection System (TPS), with no concerns noted, as the STS-125 crew close in on three landing opportunities at the Kennedy Space Center on Friday \u2013 weather permitting.
