More scaffolding will be built as areas are identified. Feel all the inspections will be done in next two or three days and will be able to provide good maps of damage and data to the engineering community,\u2019 noted the latest Shuttle Standup\/Integration report, available on L2.<\/font><\/p>\n<p>A major milestone will follow on Wednesday, when engineers carry out a TIM level evaluation of the tank, which will go some way to decide if they can viably bring ET-124 back to flight status, or if they\u2019ll need to wait for the next tank (ET-117) to arrive from the Michoud Assembly Facility \u2013 due to arrive at KSC in April \u2013 to fly with Atlantis instead.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" height=\"130\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=13815\" width=\"200\" align=\"left\" vspace=\"5\" border=\"0\/\"><font face=\"Arial\"><\/font><font size=\"2\">**Ride home through the fire and plasma of re-entry with Atlantis on STS-115 \u2013&nbsp;And&nbsp;now also with&nbsp;Discovery on STS-116&nbsp;\u2013 TWO Stunning high quality&nbsp;2hr, 355mb videos \u2013 from deorbit burn to post landing**<\/font><\/p>\n<p>Damage sustained by Atlantis herself during the hailstorm was minimal compared to her ET, and repairs have been proceeding without issue. <\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018Micro-inspections on left wing of orbiter are complete, and macro-inspections on lower surface are complete,\u2019 noted a March 13 update. \u2018Twenty-seven of the 32 TPS repairs identified are complete. There was minor TPS damage from the hail; will repair this concurrently with the inspections and the work taking place on the tank. <\/font><\/p>\n<p>\u2018Completed a Ground Ops risk assessment for RCC NDE work, and identified actions. Meeting to ensure actions are complete. When the actions are completed, the high crew will begin building access over that area.\u2019<\/p>\n<p>A \u2018Thermography paper\u2019 will be repaired for Atlantis\u2019 tiles on Friday, with work set to continue on finalizing the repair effort next week. <\/p>\n<p><font face=\"Arial\" size=\"2\">While those evaluations continue, the focus on the orbiters continue unabated. While it\u2019s not stated, some of the \u2018poke outs\u2019 seen with Atlantis do raise some interesting questions in regards to the original launch date for STS-117, which would have been this Thursday. <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018On Atlantis, (a problem was found) from backing out of a mod that resulted in stumbling onto an ECO sensor wiring issue. Wires for all four sensors runs through the same ten foot length in one harness,\u2019 added a NASA report. \u2018The wires probably need to be separated, and this condition is on all vehicles.\u2019 <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">Also noted was the SRB hydraulic accumulator issue \u2013 which is separate from the recent problem with the erratic chamber pressure in one OPT (Operational Pressure Transducer) \u2013 which led to the removal and replacement of all six (three on each booster) OPTs. <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018Troubleshooting was performed last Thursday on the SRB hydraulic accumulator and saw no change in quantity percentage. The SRB accumulator will need more testing and will likely need to be replaced,\u2019 added acquired NASA information. \u2018Atlantis will power up briefly to support additional SRB hydraulic accumulator troubleshooting and Orbiter\/SRB data snapshots.\u2019 <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">Processing continues with Discovery and Endeavour, with both flows classed as green, without any significant issues.<\/font><\/p>\n<p><font face=\"Arial\"><\/font><font size=\"2\"><em>Further articles will follow.
