Flow timelines have been aided by what is now classed as a \u2018best case\u2019 scenario of an October 8 launch date for STS-125 on the latest Integrated Milestone Chart \u2013 which also documents Atlantis\u2019 two additional flights of STS-128 and STS-131 that will follow.<\/p>\n<p>No major processing milestones are being worked on Atlantis at this time, as she undergoes a series of functionality tests on specific elements of hardware.<\/p>\n<p>\u2018Completed the push test on the ET doors. In process of working MPM (Manipulator Positioning Mechanisms) functional (UPDATE: Complete with no anomalies). Completed test on starboard side; working port side,\u2019 added the Stand-up report. <\/p>\n<p>\u2018Installed R2C on 17R (Reinforced Carbon Carbon (RCC) Panels). Working to configure the left side. Put chin panels up and will be torquing them in place.\u2019<\/p>\n<p>Processing information on Friday did point to continued troubleshooting on Atlantis\u2019 Fuel Cell 3, which is undergoing evaluations on its flow meter. So far, the device appears to be in good working order, though engineers will \u2013 as always \u2013 double check the results. <\/p>\n<p>\u201cFC-3 flow meter, picked back up with troubleshooting. The Flow meter was powered up using the external power supply and Nicolet recorder. No over-current was observed. Data review is underway. This process will be repeated today for all of 1st shift to allow the circuit to \u201ccook\u201d.\u201d<\/p>\n<p>Atlantis will also have to wait a little longer for the replacement of her aft radiator retract hose \u2013 which \u2018famously\u2019 kinked during payload bay door closure pre-launch (STS-122) before being guided back into place via a long pole. <\/p>\n<p>The replacement hose was accidentally contaminated before being shipped from the vendor, though they spotted the mistake and will now ensure the hose is cleaned before heading to KSC for installation.<\/p>\n<p>\u201cFreon coolant loop 2 de-servicing completed to support R&amp;R of the aft radiator retract hose assembly,\u201d added processing information on Friday. \u201cAft radiator retract hose assembly is planned to start (pending arrival of the assembly) and continue on Saturday. The installation will pick back up next Monday. <\/p>\n<p>\u201cYesterday, during final inspection for shipping it was determined that the flex hose cleanliness was compromised and will require cleaning at (the manufacturer) prior to shipment.

As part of her processing milestones, Endeavour\u2019s SSMEs have now been removed from her aft, ahead of being refurbished for a future mission. <\/p>\n<p>\u201cIn process of removing engines today. Will begin engine removal from OV-105 this afternoon and continue this work until midnight. Will complete this work until all three engines are back in the engine shop by end of shift on Friday. (Engines 2 and 3 removed first, Engine 1 last).<\/p>\n<p>\u201cFRCS (Forward Reaction Control System) checkout, which was completed Thursday. Will begin OMS (Orbital Manuvering System) pod checkout next week. Continuing with post-flight TPS (Thermal Protection System) inspection (90 percent complete).\u201d<\/p>\n<p>Now a fleet-wide issue, the radiator retract hoses on Endeavour are also being checked, after she joined her two sisters in the kinked hose club post STS-123. However, opening checks \u2013 involving the use of x-rays \u2013 are showing no damage to the hose in question.<\/p>\n<p>\u201cPerformed x-rays earlier in the week on the forward starboard flex hose. There were no issues with the x-ray. Will be doing payload bay door cycles next week to determine if hose retracts into the box.<\/p>\n<p>\u201cRadiator retract container for Endeavour (forward starboard contingency item) can be delivered to Huntington Beach for (testing) around May 9. Targeting first week of June for delivery back.\u201d<\/p>\n<p>Another post STS-123 element involves work on the FES (Flash Evaporator System) primary A controller, which failed shortly into Endeavour\u2019s launch last month. Testing has shown it was the hardware that failed, as opposed to associated Ground Support Equipment (GSE). <\/p>\n<p>\u201cFES primary A controller troubleshooting is complete to date. The FES GSE was mated to the Primary B controller and successfully tested, validating the GSE. As a result, it is suspected that the FES Primary A controller has failed,\u201d added processing information.<\/p>\n<p>\u201cFor FES primary controller, looking at April 28 delivery date to support R&amp;R on OV-105. Weekend work: SSME removal post ops, side hatch limit switch rigging, and ET umbilical door inspections.\u201d<\/p>\n<p><b><i><u>External Tank Status:<br \/><\/u><\/i><\/b><br \/>Workers at the Michoud Assembly Facility (MAF) in New Orleans are continuing their efforts to protect the realigned delivery dates for ET-127 and ET-129 \u2013 both required for the launch of Atlantis on STS-125 and Endeavour\u2019s supporting role as the LON-400 rescue mission requirement.<\/p>\n<p>The new delivery dates are fluid, as production on the tanks continues, with a clearer idea of how the new shipping dates will relate to the downstream manifest expected in around a month.<\/p>\n<p>Classed as \u201cstreamlined processes\u201d on specific areas of the tanks \u2013 the status of the ETs were threatening to cause several months of delays.

Doing preps inside intertank for harnesses. Had all LO2 ice\/frost ramp base sprays done, and they are in trim. Six more are in final trim stages.<\/p>\n<p>\u201cLOX elbow has been delivered and should be installed at end of week. Then, will deliver aft interface hardware to the tank for installation.\u201d <\/p>\n<p>Interestingly, the following tanks \u2013 starting with ET-130 \u2013 are not showing any issues with their production flows, which has been aided further by the recent delays in the near term manifest.<\/p>\n<p><b><i><u>Manifest Latest:<\/u><\/i><\/b> <\/p>\n<p>Shuttle managers conducted a SSP (Space Shuttle Program) Council meeting this week, which discussed the current manifest situation, the requirements of the Constellation program (CxP) during the final couple of years of shuttle operations, and the subsequent transition. <\/p>\n<p>Headed by shuttle manager John Shannon, notes from that meeting point to an ability to still complete the remaining manifest by 2010 \u2013 though there are \u201cchallenges\u201d. <\/p>\n<p>\u201cHad a SSP Council meeting, which focused on three topics: 1) Manifest supportability \u2013 team members discussed how their element supports the manifest.
