Endeavour STS-127 Pad Flow Latest:<\/p>\n
Engineers have ably guided Endeavour through her pre-launch processing milestones, despite time constraints relating to turning the vehicle around after the successful tanking test at the start of the month.<\/p>\n
No technical issues are being worked on the vehicle, with the only additional work relating to cosmetic damage observed on the left hand Solid Rocket Booster (SRB) and the removal of cracked foam from External Tank (ET-131\u2019s) LO2 Feedline.<\/p>\n

\u201cET-131-TS-0019, the repair of cracked foam on the ET LO2 feedline began on Wednesday. Left-hand SRB paint defect repair: Sanding and sampling of the area is complete.<\/p>\n
\u201cSamples were taken to the lab to verify the presence of rust. Eddy current testing revealed no anomalies. Primer and top coat application are complete.\u201d<\/p>\n
Nominal procedures completed in the recent flow included the programming of the WLE IDS (Wing Leading Edge Impact Detection System) units, which have a primary role of \u201cfeeling\u201d any debris impacts on the orbiter\u2019s RCC (Reinforced Carbon Carbon) panels during ascent.<\/p>\n
Rocket launch schedules (adsbygoogle = window.adsbygoogle || []).push({});<\/p>\n \u201cWing Leading Edge flight programming was successfully completed on all units. Range safety system re-programming and battery change out is complete. The flight doors have been installed.<\/p>\n \u201cLOX storage tank sampling was completed (earlier in the week). APU\/HPU (Auxiliary Power Unit\/Hydraulic Power Unit) cart GN2 sample is complete with nominal results. The GH2 battery recharge was rescheduled for late Wednesday.\u201d<\/p>\n The STS-127\/2J\/A mission package includes the Japanese Experiment Module \u2013 Exposed Facility (JEM-EF) and the Japanese Experiment Logistics Module \u2013 Exposed Section (ELM-ES) as well as the Integrated Cargo Carrier \u2013 Vertical Light Deployable (ICC-VLD).<\/p>\n Atlantis\/STS-129 Processing Latest:<\/p>\n Positive news has been reported on the results of mold impressions taken on Atlantis\u2019 Window 5 pressure pane, which has found the damage \u2013 suffered when a work light knob was found to be embedded between the pane and the dashboard \u2013 is not serious enough to warrant the pane\u2019s replacement.<\/p>\n \u201cThe window was inspected after the knob was removed. The deepest defect is approximately 0.0003\u201d depth, the reportable depth threshold is 0.0015\u201d and above,\u201d noted findings from the mold impressions taken on Monday night, and acquired by L2.<\/p>\n Thanks to the successful removal of the knob \u2013 via the pressurization of the crew cabin in tandem with the application of dry ice to shrink the knob \u2013 no additional damage was suffered to either the pressure pane or the surrounding hardware.<\/p>\n Had that removal procedure failed, more intrusive methods would have been employed, which in turn had the potential to increase the damage on the pane.<\/p>\n \u201cPictures show that it is unlikely metal from the knob is still trapped in the defect,\u201d added the findings. \u201cWhether the coating requires replacement will be discussed.\u201d<\/p>\n The news means Atlantis remains on track for a launch No Earlier Than (NET) November 12, 2009, on a mission that will deliver the Express Logistics Carriers 1 & 2 (ELC-1 and ELC -2), along with SASA and MISSE (Materials on International Space Station Experiment) 7A and 7B, to the Space Station.<\/p>\n Nominal processing work has continued throughout the window evaluations, highlighted by troubleshooting on the radiator flow control valve \u2013 an issue noted during Atlantis\u2019 STS-125 mission to service the Hubble Space Telescope, along with the removal and replacement of the S-Band right-hand lower antenna.<\/p>\n \u201cAmmonia boiler flushing continues and should terminate late Wednesday. Freon coolant loop 1&2 functional checks were completed on Tuesday. Engineering is evaluating data results,\u201d noted processing information on L2.<\/p>\n \u201cS-band thermography was completed Tuesday. S-band antenna removal picked up Tuesday night. Re-installation is planned for Thursday.\u201d<\/p>\n Discovery\/STS-128 Processing Latest:<\/p>\n \u201cStructural leak checks will be completed this week,\u201d noted the Shuttle Standup\/Integration report on L2, citing United Space Alliance (USA) Ground Operations. \u201cOrbiter final power down occurred Tuesday at 1300 EDT.<\/p>\n \u201cWeight and CG (Center of Gravity) work done on Wednesday, and the vehicle will transfer to the OTS (Orbiter Transporter System) on Thursday, July 9. The vehicle should be ready to roll to the VAB on July 14.\u201d<\/p>\n Ahead of transferring the veteran orbiter on to her taxi ride to the VAB, engineers worked through the final pressurization of the vehicle\u2019s landing gear. All went to plan, bar an issue with a transducer associated with the reading of the tire pressures.<\/p>\n \u201cFinal tire pressure for flight, Nose Landing Gear was completed last night. Main Landing Gear will be completed late Wednesday.<\/p>\n \u201cPressure transducer milli-volt reading does not correlate to tire pressure. Troubleshooting plan is to take the pressure panel to the highest acceptable pressure band for the tires and then check the transducer milli-volt reading.<\/p>\n \u201cIf bad then the plan is to take the pressure panel to the lowest acceptable pressure band for the tires and if the transducer milli-volt reading is still bad then we\u2019ll reconfigure with a different pressure panel.\u201d<\/p>\n The actual mating of Discovery to the OTS will occur during first shift on Thursday, with Call to Stations (CTS) at 6am local time.<\/p>\n L2 members<\/em><\/em>: Documentation \u2013 from which the above article has quoted snippets \u2013 is available in full in the related L2 sections, now over 4000 gbs in size.<\/em><\/em><\/p>\n","protected":false},"excerpt":{"rendered":" Endeavour is now proceeding through the complex ballet of S0007 Launch Countdown operations for Saturday\u2019s launch attempt of STS-127 to the International Space Station (ISS).
