The only real issue is with one of her passengers, who is confirmed to be ill, resulting in the 24 hour delay to EVA-1, allowing for&nbsp;Schlegels\u2019 spacewalk tasks to be carried out by Stanley Love.<\/p>\n<p>Visually, the ripped OMS Pod blanket brings back memories of Atlantis\u2019 STS-117 event, where a protruding piece of blanket has to be \u2018prodded\u2019 back down by spacewalker Danny Olivas, during that mission\u2019s EVA-3. A similar task may be required during STS-122. <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" height=\"190\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=40246\" width=\"326\" align=\"left\" vspace=\"5\" border=\"0\/\">Interestingly, the location of the rip is different to that observed during STS-117, where the blanket had become \u2018unstitched\u2019 from the TPS (Thermal Protection System) tile on the forward section of the pod. <\/p>\n<p>STS-122\u2019s tear is further back on the opposite pod and may hold less risk of peeling back during re-entry. <\/p>\n<p>It may also have all manner of different thermal and dynamic characteristics than those evaluated for STS-117, ensuring the decision to either repair or leave as-is may take at least another 24 hours. <\/p>\n<p>\u2018Blanket on Starboard OMS Pod observed to have been lifted at one corner (Thermal Blanket Installation Date \u2013 4\/29\/85, 1.06 inch nominal thickness,\u2019 noted information in an expansive overview presentation.<\/p>\n<p>\u2018Filler bar perimeter, no stitching to adjacent blankets. Installation paperwork being reviewed to determine if sub-insulation (ramping) is present. Gr\/Ep honeycomb structure beneath \u2013 defining details (further imagery will be obtained and evaluated, obtain images on an opportunity basis (video and Focused Inspection)).\u2019<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" height=\"169\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=40245\" width=\"220\" align=\"left\" vspace=\"5\" border=\"0\/\">Back-up data is aplenty, with OMS Pod blankets coming away from the structure something that is not an uncommon event. This is seen in flight history notes, ranging from STS-117\u2019s event, to some rather scary images from earlier flights in the shuttle program. Each time the orbiter returned home safely.<\/p>\n<p>\u2018STS-74 (Atlantis\u2019 15th Flight): Blanket damaged along a previous patch repair. No Structural damage noted. Port side OMS Pod,\u2019 noted the examples, some of which are listed below.<\/p>\n<p>\u2018STS-50 (Maiden Voyage of OV-105\u00e2\u20ac\u2122s OMS Pods): Left Hand OMS FIB damages was initiated by Debris damaging the tile. Right Hand OMS FIB lifted along the tile interface. No Structural damage to substrate.<\/p>\n<p>\u2018STS 6 (Challenger\u2019s Maiden Voyage): Analysis concluded the AFRSI blanket loss was do mechanical forces by either foreign object impact or aerodynamic forces. <\/p>\n<p>\u2018There was no significant thermal exposure (&gt;1200F), majority of insulation lost after entry heating. Structural integrity of the undamaged blankets was not degraded. Resulted in the development of C-9 ceramic coating.\u2019<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" height=\"210\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=40249\" width=\"278\" align=\"left\" vspace=\"5\" border=\"0\/\">\u2018STS-95 (Discovery Flight 25): Carrier panel on Y-web door lifted and cracked. Reported on orbit by crew. Overtemp caused delamination of the outer layers of the Y-web door.<\/p>\n<p>\u2018The exposed section of the carrier panel eroded away&nbsp;around 6 inches of the panel. Removal of the door found no charring or delamination to the IML surface of the composite structure or overtemp to the internal cavity.\u2019<\/p>\n<p>The point that is obvious from the presentations relates to the observation of&nbsp;much more serious damage being seen&nbsp;on previous flights, with the worst cases resulting in repairs back inside the Orbiter Processing Facility (OPF). <\/p>\n<p>Any repair on orbit via an EVA would likely be called to mitigate such additional processing work, ahead of Atlantis\u2019 STS-125 this summer.<\/p>\n<p>Meanwhile, other areas of interest on the orbiter have also listed, <\/p>\n<p>\u2018Gap filler is protruding around a maximum of 0.44\u201d over a length of 6\u201d \u2013 Installation history is being pulled,\u2019 which relates to an area of interest on the same starboard OMS Pod on Atlantis.<\/p>\n<p>Whereas on the opposite pod, \u2018Blanket OML is protruding maximum 0.48\u201d over a length of 11\u201d Blanket installed in 1984 \u2013 Not bonded to adjacent tile prior to flight. RPM imagery will be utilized assess interface,\u2019 was also observed.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" height=\"159\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=40247\" width=\"305\" align=\"left\" vspace=\"5\" border=\"0\/\">Flight Day 3\u2019s RPM imagery was also used to check on a small area of damage on Atlantis FRCS (Forward Reaction Control System) \u2013 helping confirm there are no concerns over what is mainly cosmetic damage to the TPS.<\/p>\n<p>\u2018Tile damage is adjacent to thruster thermal barrier. Tile seals to thermal barrier for approximately 1.8\u201d. Damage appears to be shallow relative to tile thickness,\u2019 added the presentation. <\/p>\n<p>\u2018Thermal barrier seal is verified each flow to preclude flow path to structure. Majority of design seal remains to ensure no flow past interface.\u2019<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" height=\"204\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=40248\" width=\"271\" align=\"left\" vspace=\"5\" border=\"0\/\">Launch imagery also continues to be checked over, though the highlight appears to be at SSME (Space Shuttle Main Engine) ignition, where a whole tile liberated from the aft end of the left stringer pod.<\/p>\n<p>Pad inspections \u2013 which have been carried out and found the structures to be in \u2018better\u2019 condition than normally observed \u2013 have not found any remains of the tile, which was likely incinerated. <\/p>\n<p>However, this issue is not causing any concern, due to the lack of critical systems in the immediate vicinity. The location is near two vernier RCS (Reaction Control System) thrusters, but they are not close enough to where the tile liberated from to be an issue.<\/p>\n<p>Ironically, despite the tear in the OMS Pod blanket, this appears to be one of the cleanest flights ever, pending full evaluations&nbsp;on the RPM imagery taken on Flight Day 3. Updates will follow after those evaluations have concluded.<\/p>\n<p><em><u>Endeavour\/STS-123:<\/u><\/em><\/p>\n<p>Good news for Atlantis\u2019 younger sister, following a couple of days of meetings that concluded with the green light to allow Endeavour to rollover to the Vehicle Assembly Building (VAB) after all. This is scheduled for Monday.<\/p>\n<p>Last week, a HEPA filter contamination problem led to a decision that Endeavour would not be able to support STS-122 as the LON (Launch On Need) orbiter, leading to a debate about Discovery\u2019s ability to be processed in time for stacking with ET-126 and the attached twin Solid Rocket Boosters, in order to take over the role.<\/p>\n<p>Following several meetings, engineers concluded that contamination had not breached critical systems on Endeavour \u2013 which was the major concern \u2013 allowing her to continue with the flow towards stacking for both LON and her primary STS-123 mission, currently scheduled to launch next month.<\/p>\n<p><font color=\"#0000ff\"><\/font><font face=\"Arial\"><\/font><font color=\"#0000ff\" size=\"2\"><em>Click here for MaxQ\u2019s Stunning Apollo I\/Challenger\/Columbia&nbsp;Tribute&nbsp;Video \u2018New Days Will Rise\u2019.<\/em><\/font><\/p>\n<p><em><font face=\"Arial\" size=\"2\">**STARLIGHT: NEW STS-117 MISSION&nbsp;REVIEW&nbsp;MUSIC&nbsp;VIDEO**<\/font><\/em><em><font face=\"Arial\" size=\"2\">&nbsp;\u2013 STS-118 and STS-120&nbsp;Mission review video also available.<\/font><\/em><font face=\"Arial\"><\/font><font size=\"2\"><em>&nbsp;<\/em><\/font><\/p>\n<p><font color=\"#ff0000\">**ROCK YOU LIKE A HURRICANE: STS-117 MISSION&nbsp;REVIEW&nbsp;MUSIC&nbsp;VIDEO \u2013 AS SEEN BY THE STS-117 CREW!!**<\/font>&nbsp;-.<br \/><font size=\"1\">(<em>Video section is FREE, but you need to sign up as a member of the forum to enter the video section of the site.
