As far as the estimated repair schedule, work on the tank is only down by a day or two \u2013 well within the NET June 8 launch possibility. <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">However, those tank repairs have gotten in the way of the requirement to remove Atlantis\u2019 SSMEs (Space Shuttle Main Engines), due to scaffolding \u2013 which was erected for the ET-124 repairs \u2013 providing lower than required clearance for the removal of the engines. <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018During a walkdown in preparation for engine removal, several scaffolding issues were noted. To ensure ET-124 repair efforts were not impacted, engine removal will be rescheduled to begin on April 24,\u2019 noted processing information acquired by this site at the start of this week. <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018This change in the schedule is not expected to impact the rollout date of May 6 nor the NET launch date of June 8.\u2019 <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\"><br \/>\n<\/font><\/p>\n<p><font face=\"Arial\" size=\"2\"><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 color=\"#0000ff\" 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><\/font><\/p>\n<p>This was explained further by information produced a few days later, which noted clearances of only 1.5 inches, which isn\u2019t enough, given the stack is capable of moving around three inches while inside the VAB (Vehicle Assembly Building). <\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018Reviewed engine removal timeline and procedure: A question was posed to the Loads Panel on the clearances to the scaffolding and how much the vehicle would move once the engines are removed. Checked the clearances on the scaffolding, and in some areas have scaffolding clearance of only one inch or 1.5 inches. The estimate is the vehicle could move as much as three inches. <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018Postponed engine removal until remove scaffolding. This currently fits in the schedule, but makes the schedule a bit tighter. There was another question of how much the vehicle would move with only one engine removed, but that would still be too close.\u2019 <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">As stated, this does not alter the targeted May 8 rollout of Atlantis back to Pad 39B, although she\u2019ll be rolling out with one of Endeavour\u2019s SSMEs, as noted in a processing report: \u2018SSME #2 will be swapped with OV-105 (Endeavour).\u2019 <\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">The reason for the swap is believed to be&nbsp;because&nbsp;engine 2 on Atlantis needs to have its LPOTP <b><\/b>(low pressure oxidizer turbo pump<b><\/b>) replaced, when they remove it for the RepliSet contamination inspection.&nbsp;<\/font><\/p>\n<p><font face=\"Arial\" size=\"2\"><br \/>\n<\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">Endeavour&nbsp;has already had her&nbsp;SSMEs removed to check for contamination, which proceeded well, despite some level of contamination found, although no notes of concern were raised.
