\u201cContinuing to work main engine installation preps. Continuing with TPS (Thermal Protection System) processing, with 103 cavities remaining for tile bonding.\u201d<\/p>\n
Discovery is being processed for what is currently her final flight \u2013 pending what is only a very slight possibility of an extension, or the gaining of the notional STS-135 mission, should managers opt to remove Atlantis from converting her STS-335 flow into a baselined mission.<\/p>\n
With the addition of two EVAs, \u201ccrew loading\u201d (training) schedules pushed the launch date out to late October, although final updates on the schedule for other visiting vehicle to the ISS \u2013 due to Dual Docked Operations (DDO) constraints \u2013 and solar beta angle cutouts, need to be worked prior to an official launch date NET announcement.<\/p>\n

\u201cET-137 (VAB HB-4E): TPS repairs are continuing and on schedule to be completed (by weekend). ET mate preps continue with inspections and platform operations.\u201d<\/p>\n
STS-134 Processing Latest:<\/p>\n
Endeavour\u2019s flow inside OPF-2 is also on track, even if managers decide to advance the flight ahead of STS-133 in the mission order, as has been intimated as a possibility via the ongoing evaluations.<\/p>\n

Work is also taking place on installing a Boundary Layer Transition (BLT) Detailed Test Objective (DTO), which involves a small bump being added to one of the tiles on the orbiter\u2019s belly. The goal of the experiment is to measure the effects of increased heating from an early boundary layer transition as the orbiter returns to Earth.<\/p>\nDiscovery has been the only orbiter to fly with the BLT DTO, opening with STS-119, prior to the Program Requirements Control Board (PRCB) approval to add a protuberance to one of Endeavour\u2019s tiles.<\/p>\n
\u201cGot approval to do the BLT on OV-105 (Endeavour) similar to what was done on OV-103 (Discovery). There was discussion regarding protuberance height. The team brought forward rationale for 0.5 inch height, which will go forward to the Program for approval,\u201d noted the Standup report, with a full article based on the resulting PRCB presentation to follow.<\/p>\n

Meanwhile, with the Mobile Launch Platform (MLP) \u2013 used during STS-132\u2019s launch \u2013 now back inside the VAB, preparations for booster stacking are picking up inside the Rotation Processing and Surge Facility (RPSF).<\/p>\n\u201cSRB BI-145 \/ RSRM 113 (RPSF): Left Aft Booster Buildup: Acrymax application to RT-455 complete. Preps to transfer of AFT Booster to pallet in work. Right Aft Booster Buildup: Aft skirt transition floor plate RTV complete,\u201d noted processing information.<\/p>\n
With stacking set to take place after managerial approval, Endeavour\u2019s ET-138 \u2013 the final ET to be constructed at the Michoud Assembly Facility (MAF) \u2013 is set to arrive at the Kennedy Space Center (KSC) next month. Engineers in New Orleans are tracking a June 20 completion date, followed by a rollout ceremony on July 8.<\/p>\n
\u201cET-138: In Building 420, the TPS closeouts are going well. Testing is going well. Shakedowns continue. Are off the top of most of the hydrogen tank, and have started the process of pulling the scaffolding out of the intertank,\u201d noted contractor Lockheed Martin on the Standup report.<\/p>\n
\u201cOnly around half a day down from the commitment day right now. Still building confidence that they will hit the ET complete date of June 20.\u201d<\/p>\n
STS-335\/STS-135 Processing Latest:<\/p>\n
Atlantis is still at least a few weeks away from knowing if she\u2019ll get to fly on a baselined mission, with her current processing flow in OPF-1 continuing on the pre-planned STS-335 LON (Launch On Need) rescue support for the final scheduled flight of the shuttle.<\/p>\n
STS-135 Specific Articles: http:\/\/www.nasaspaceflight.com\/tag\/sts-135\/<\/p>\n
\u201cRCC (Reinforced Carbon Carbon) thermography inspections are on-going. Orbiter window inspections continue with completion expected Monday. Windows 9 and 10 will be inspected next week. FRCS (Forward Reaction Control System) functional and checkout is complete. OMS pod functional checkout continues into next week,\u201d noted NTD processing information, which also noted the addition of a ninth IPR to her flow.<\/p>\n
\u201cNew IPR 0009 \u2013 Detected During FRCS functional and checkout. GSE (Ground Support Equipment) delta pressure transducer stuck at upper limit. Troubleshooting released the transducer indication. Weekend Work: None.\u201d<\/p>\n
Following Atlantis\u2019 highly successful STS-132 mission, her flight crew are being debriefed by managers, as the IFA (In Flight Anomaly) review closes in on being presented to the PRCB next Thursday.<\/p>\n

As part of the post-mission flow, the orbiter\u2019s Flow Control Valves (FCVs) have been removed and shipped back to their fabricator Vacco in California. There they will be inspected for any signs of cracks, relating to the mitigation of liberations from the poppet area of the valve, as seen during STS-126, leading to a year long investigation into the incident.<\/p>\n\u201cOV-104 (STS-132): FCV (Flow Control Valve) removal has been completed. The FCVs from the last flight are back at Vacco,\u201d noted KSC Integration. \u201cNext week, will pick up with OMS Pod checkout. Continuing with post-flight TPS inspection; 70 percent complete at this time.\u201d<\/p>\n
STS-335 was assigned ET-122, a tank that is undergoing repairs after suffering damage during Hurricane Katrina. Processing of the tank has been proceeding to plan, although a reference to the evaluations on the final manifest running order was noted on the latest ET-122 flow report.<\/p>\n
\u201cET-122: Making progress on the critical path. Have the STS-134 crew coming in to look at their ride,\u201d the Standup report noted, before adding: \u201cThey will be shown both tanks (ET-122 and ET-138) since it is not certain which one will end up as theirs.\u201d<\/p>\n
