The orbiter was powered down for the period of hyper deservicing and engineering access. <\/p>\n \u2018The Orbiter was successfully spotted in OPF-1 on the 1st attempt at 1430L. S0069 Integrated Roll In Ops picked up after the Orbiter was spotted,\u2019 noted processing information on Thursday. <\/p>\n \u2018RH\/LH T-O connections, Fuel Cell power down, jack and level, White Room extension, have been completed. Access to the crew module has been established. Comm. and BFS GPC (General Purpose Computer) deactivation are complete. S0069 operations are on schedule and will continue today. Payload Bay Doors will be opened on Sunday.\u2019<\/p>\n Atlantis\u2019 processing flow will be fascinating to follow, as the orbiter transitions from a module carrying vehicle, to a Hubble servicing ship. <\/p>\n Lining up in the payload bay will be the Super Lightweight Interchangeable Carrier (SLIC), Orbiter Replacement Unit Carrier (ORUC), Flight Support System (FSS), and the Multi-Use Logistic Equipment Carrier (MULE). <\/p>\n Hosted on those elements will be the replacement Wide Field Camera 3 for Hubble, along with its new batteries, a Fine Guidance Sensor, and the Spectrograph Rate Sensor Units. Also observed in the payload bay is the IMAX camera, which will take movie footage of the mission.<\/p>\n However, while this payload is unique to Atlantis, it\u2019s the modifications that are to be utilized for increased safety that will gain their debuts with STS-125. <\/p>\n While some of the improvements are awaiting full approval by the Space Shuttle Program (SSP), the list is fascinating by way of using lessons learned from previous flights, in order to increase safety margins. Listed below are just a few of the modifications noted. <\/p>\n Already classed as baselined is \u2018Fiducial Markings on Nose Cap RCC\u2019, markings that will appear as a cross on the nose cap of Atlantis. This will enable more accurate and expeditious coordinate location identification for inspection and damage assessment activities. <\/p>\n \u2018Implements fiducial markings to facilitate on-orbit imagery X-Y-Z coordinate location to allow for more efficient damage assessment during the mission,\u2019 noted one of the numerous mission baseline presentations.<\/p>\n \u2018Permanent reference marks will be added using Black Sharpie marker at 14 original Shuttle Entry Air Data System (SEADS) locations on nose cap. Reduces \u2018uncertainty\u2019 from ~5\u201d without marks to ~0.5-1.0\u201d.\u2019<\/p>\n Implementation of Protective Window Shields \/ On-Orbit Installation: This modification \u2013 awaiting official approval \u2013 will add safety margins in the event of an MMOD (micrometeoroid\/orbiting debris) strike on the windows in question \u2013 and allows for the potential for damaged shields to be removed on orbit.<\/p>\n \u2018The bonded polycarbonate window shields concept was developed in 2006 but it was determined that the Lexan would have a detrimental effect on high aperture photography. A new concept was developed to allow removal and installation of the polycarbonate shields on-orbit<\/p>\n \u2018A single layer of cloth is attached over the shield with Velcro to act as a shade; rear windows include tethering capabilities. Rear window shields will be installed for launch to protect the windows; Overhead window shields will be installed on-orbit after photographs are taken.<\/p>\n \u2018Utilizes existing overhead windows 7 and 8 clamps and rear windows 9 and 10 Velcro attachment locations without invalidating the crew module window basis of certification.\u2019<\/p>\n Main Landing Gear Door (MLGD) Thermal Barrier Cavity Protection: This element is due to be certified in April, which \u2013 should it be approved \u2013 will see the installation of a thermal inhibitor on the barrier, in order to prevent potential failure of the MLGD environmental seal.<\/p>\n Interestingly, the reference to \u2018vulnerability\u2019 is based on a number of debris strikes to that area of the orbiter. Atlantis\u2019 STS-122 saw no noticeable strikes, and may as a result change this requirement.<\/p>\n However, if approved, the thermal inhibitor \u2013 constructed of a rigidized batting material enclosed in a sleeving \u2013 would be used to expand to seal the cavity during exposure to excessive heating and protect the environmental seal area from reaching an over-temperature conditions.<\/p>\n \u2018Arc jet testing demonstrated the ability of the thermal inhibitor to reduce the temperature at the environmental seal for the condition of a breach past the MLGD thermal barrier. All material and system testing performed to-date proved that additional insulation capability is provided by the thermal inhibitor.<\/p>\n \u2018Thermal inhibitor preliminary development schedule supports implementation on OV-104 for STS-125. Material qualification is scheduled for completion on 2\/18\/08, with production hardware \/ certification is expected to be complete on 4\/17\/08.\u2019<\/p>\n ET Door Uplock Latch Actuator Modification: This calls for the redesign of the existing ET (External Tank) door uplock latch actuators (LH and RH) to reduce the maximum stall torque range. \u2018The modified actuator test showed consistent stall torque results within 900 to 1,151 in-lbs under all test conditions, significantly reducing the risk of yielding the uplock mechanism<\/p>\n \u2018The new design included reducing the spring force on the torque limiter friction disks by reducing the Belleville spring thickness, adding a spacer to fill the gap, and the ball pockets ground for smoother surface and slightly increased depth to improve consistency.\u2019<\/p>\n UPDATE:<\/u><\/em> The ET Door Uplock Latch Actuator Modification will no longer being implemented for the HST flight. Managers have decided to focus attention on implementation of BRI-18 tile around the Main Landing Gear Doors and the ET Doors. To carry out both modifications is not viable for Atlantis\u2019 OPF flow ahead of STS-125.<\/p>\n **CLICK HERE to review our series of articles on STS-125 and STS-400 LON**<\/em><\/p>\n The month long delay to STS-124, caused by production issues with ET-128 and the Beta Angle cut out, aren\u2019t expected to cause any issues with STS-125\u2019s schedule, and ET-127 \u2013 the tank that will fly with Atlantis \u2013 is on schedule at the Michoud Assembly Facility (MAF) in New Orleans.<\/p>\n \u2018On ET-127, are continuing longeron preps; installed four ice\/frost ramp brackets,\u2019 noted recent processing information, adding that the work to ET-128 will not result in a slowdown on the STS-125 tank. \u2018Will keep resources working on ET-127.\u2019<\/p>\n As reported previously, the additional factor involved with an on-time launch of STS-125 is Endeavour. Currently on Pad 39A awaiting launch on STS-123, Endeavour is required to be processed in time to be rolled out to Pad 39B, where she will remain as the LON (Launch On Need) vehicle during the launch of Atlantis from Pad 39A.<\/p>\n Once stood down from that requirement, she will be rolled back \u2013 partly \u2013 down the crawlerway, before being moved on to Pad 39A in preparation for STS-126. <\/p>\n A smooth STS-123 mission thus required to support STS-125, and a full pre-Flight Readiness Review (FRR) preview will be published on this site in the next few days.<\/p>\n L2 members<\/em><\/font>: All documentation \u2013 from which the above article has quoted snippets \u2013 is available in full in the related L2 sections, updated live.<\/em><\/p>\n <\/font><\/font>Click here for MaxQ\u2019s Stunning Apollo I\/Challenger\/Columbia Tribute Video \u2018New Days Will Rise\u2019.<\/em><\/font><\/p>\n **STARLIGHT: NEW STS-117 MISSION REVIEW MUSIC VIDEO**<\/font><\/em> \u2013 STS-118 and STS-120 Mission review video also available.<\/font><\/em><\/font> <\/em><\/font><\/p>\n **ROCK YOU LIKE A HURRICANE: STS-117 MISSION REVIEW MUSIC VIDEO \u2013 AS SEEN BY THE STS-117 CREW!!**<\/font> -.

**LIVE updates on Atlantis STS-125 Processing Flow and STS-122 Post Flight**<\/em><\/font><\/p>\nThe most obvious signs of that transition will be in the payload bay, as she receives the multitude of components required for SM-4. <\/p>\n
This is an element associated with the inspections of the vehicle by the Orbiter Boom Sensor System (OBSS) \u2013 which will hold more responsibility for checking for any ascent related damage, given the lack of the RPM (Rbar Pitch Maneuver) due to the non-involvement of the ISS on this mission. <\/p>\n
\u2018Implements polycarbonate window protective shields on Orbiter pressure panes (W7, W8, W9 and W10) to reduce possibility of window breakage and accommodate launch and on-orbit removal \/ installation,\u2019 added the presentation. \u2018A thin polycarbonate sheet installed at current shade attachment locations has demonstrated the ability to prevent damage by a factor of six (minimum). <\/p>\n
\u2018The current MLGD thermal barrier system has no redundancy and is vulnerable to impact damage which could allow the heat of re-entry into the cavity between the OML and the environmental seal,\u2019 added the presentation.<\/p>\n
<\/font>\u2018Maximum stall torque of 4,000 to 6,000 in-lbs from the uplock ET door latch actuator could cause uplock mechanism yielding if debris causes a jam in the ET umbilical area during actuator operation.<\/p>\nAtlantis is currently scheduled to launch on August 28, although this date continues to jump around \u2013 from early August to early September \u2013 on updated FAWG and Launch Schedule manifests.<\/p>\n
