Updates incorporating actual (past) data with projected 70 percent humidity will be performed each week.\u2019<\/font><\/p>\n Continued refinement is expected as repairs proceed, and another major meeting has been set for next week (on the 21st) to update the status of the timeline and repairs.<\/font><\/p>\n This meeting is required to further evaluate the \u2018non standard\u2019 repairs on the tank, which involves new foam being sprayed on to some of the damaged areas. Certification efforts will be focused on such repairs to ensure the tank would be safe to fly.<\/p>\n \u2018Group generally concurred with proposed methods for hardware assessment and repairs. Existing data, planned testing and demonstration were appropriate to support disposition and flight rationale,\u2019 noted a summary of the TIM meeting, in a PRCB presentation on Thursday.<\/font><\/p>\n \u2018Actions issued to support verification primarily associated with residual risk of undetected crushed foam (ice and TPS debris) and LO2 tank repair flight history assessment \u2013 Includes correlation of STS-96 to STS-117 hail environments and additional assessment of STS-96 performance (debris due to undetected damage \/ ice).\u2019<\/p>\n While a small level of repairs have already started on ET-124 \u2013 including the application of red dye to aid the assessment process and LO2 Ogive Foam\u2013<\/b>trim\/sanding \u2013 the official go-ahead to proceed with full repairs on the tank has been given.<\/p>\n \u2018Team concurred with rationale to proceed with standard repairs (allowed per engineering). Dispositions in work. Repairs possibly starting Friday,\u2019 added the presentation. \u2018Additional data required for approach proposed for non-standard repairs (i.e. forward ogive demonstration \/ verification, damage < 0.25\u201ddeep) and undetected damage.\u2019<\/p>\n This was an important milestone, given the opposing option \u2013 waiting for ET-117 to arrive from the Michoud Assembly Facility (MAF) in April \u2013 would have moved STS-117 to a June launch target. However, this \u201ctank swap\u201d option remains on the table.<\/p>\n MAF documentation shows that ET-117 will be ready for shipping at the end of March, for an April 4 arrival at KSC. The next tanks in the flow (ETs 120, 125, 126 and 128) are all on schedule.<\/font><\/p>\n Repair evaluation presentations have continued to be produced on a daily basis, as the plan to bring ET-124 back up to an acceptable flight status continue unabated. The latest presentations (Thursday) note an increased area that will be trimmed from the top of the LOX area of the ET, now reaching around 300 degrees of the circumference.<\/font><\/p>\n Further meetings are planned to discuss and evaluate the status of the repair effort, working on both the engineering and technical standpoints, as the assessment process refines the areas of damage that need to be repaired. A further 106 areas of damage were listed on Wednesday. <\/p>\n \u2018Senior Management Review scheduled for 3\/21 to review approach for non-standard repairs and acceptance of undetected damage,\u2019 noted the PRCB presentation. \u2018Forward ogive repair technical data review tentatively scheduled for early April (week of 4\/9).<\/font><\/p>\n Meanwhile, repairs on Atlantis\u2019 left wing, which suffered a small amount of damage from the freak hail storm, are almost complete.<\/p>\n \u20186 repairs remain needing repair,\u2019 a United Space Alliance presentation on Thursday listed, which also noted the need for further access requirements. \u2018Need high crew access. Platform installation to commence this week. Work scheduled for next week.\u2019<\/p>\n <\/font>Further articles will follow.
