Endeavour\u2019s Payload Bay Doors (PLBDs) were closed for flight on Saturday, with a slight concern noted on a bulb seal during checks ahead of closure. This is not likely to become a problem for flight.<\/p>\n
\u201cPayload bay doors were closed for flight on Saturday. A small slice was observed in the in bulb seal during walk-downs prior to closure,\u201d noted processing information on L2. \u201cThe discrepancy is being evaluated, and engineering will most likely process a report to fly-as-is.<\/p>\n
\u201cTorque tubes were left installed pending final resolution of the bulb seal should the PLBDs need to be reopened to support repair work prior to flight.<\/p>\n
Sunday saw the completion of ordnance installation on the vehicle, not long after it had been removed ahead of the rollaround from Pad 39B, along with Self-Contained Atmospheric Protection Ensemble (SCAPE) operations.<\/p>\n
\u201cS5009 Final Ordnance Installation\/Connection operations were completed Sunday morning,\u201d added processing information. \u201cSCAPE operations for HPU (Hydraulic Power Unit) exhaust duct plug and overboard drain line scrubber removal were completed Sunday following S5009.\u201d<\/p>\n

Monday\u2019s flow involved S0071 MPS (Main Propulsion System) and OMS\/RCS (Orbital Maneuvering System\/Reaction Control System) pressurization to flight mass, along with continuing orbiter aft closeouts. The Final Aft Confidence Test will occur during Tuesday.<\/p>\n
Also boosting the chance of making the June 13 target has been the removal of three problems reported during the pad flow, two of which related to the Solid Rocket Booster (SRB) and Range Safety System (RSS) Command Receiver Decoders (CRD).<\/p>\n
\u201cSRB Joint Heater Secondary Power failed (issue). Facility Circuit Breaker P16 removed and replaced with bench stock \u2013 closed,\u201d added processing information. \u201cRSS Ground Arm Commands not received by Command Receiver Decoders during S0017. Test codes had been loaded in the SRB forward skirts to allow unescorted access for processing.<\/p>\n
\u201cVerification of the CRDs was accomplished in the first run of S5009 at Pad B and will be verified again during S5009 at Pad A using Secure Flight Codes. This will be closed as human error.\u201d<\/p>\n

The third issue related to the ET Umbilical Well camera, which has been troublesome on all the orbiters in the fleet over recent missions. Endeavour\u2019s camera and flash system appears to be working \u2013 with the root cause likely related to the operation of the hardware via the orbiter\u2019s battery power, versus ground power.<\/p>\n
\u201cET Separation Camera. Retest is complete and good (including Flash) using Flight Laptop and cables. This issue will be closed as an Explained Condition relative to the use of ground power vs. vehicle power during testing,\u201d noted processing information, with the Orbiter Project Office adding their take on the problematic hardware.<\/p>\n
\u201cGot into testing on umbilical camera from STS-127. Camera itself worked as planned. Got 23 flashes from the flash and 23 images on the camera. Had trouble communicating with the camera long enough to check the camera settings and download and erase the images.<\/p>\n
\u201cUsed the same laptop, cables and everything else used, and it all worked fine. Not sure what problem is, may be battery configuration versus using a power cable. Will try to reload again. Camera is functional, are just having trouble getting images off camera and verifying settings.\u201d<\/p>\n
With a large amount of work taking place on the vehicle to make the June 13 launch date, Mission Management Team (MMT) co-chair Leroy Cain made a point of ensuring teams are rotating their engineers ahead of launch, to ensure the workforce is fresh for Saturday\u2019s launch.<\/p>\n
\u201cTargeting launch on June 13. Know the launch vehicle processing and schedule at KSC is tight relative to making June 13 launch. Will let folks work through the process we have laid out in front of us and will see where we get to,\u201d noted Mr Cain on the Shuttle Standup\/Integration report (L2), with the routine L-2 (Days) meeting on Thursday to be used to review if the flow is too tight to make the Saturday lift-off target.<\/p>\n
\u201cCurrently, the schedule shows we can make it; probably just need a bit of good luck with weather and other things. The plan is to have L-2 on June 11 at 10:00 ET as mentioned. Have much work to do between now and then. Are encouraged by seeing some folks trying to take a day or two off here and there for themselves and trying to give some of their folks some time off.<\/p>\n
\u201cPlease try to do that when and where you can for yourself and for your team. Need to make sure we\u2019re rested up before go to KSC for launch and get ourselves into this extremely complex mission. Have done really, really great work folks.\u201d<\/p>\n
