Discovery’s been patiently sat on the Orbiter Transporter System (OTS) for a number of days, as engineers carried out pull tests on ET-132’s intertank – the area from which several unusual foam liberations occurred during Endeavour’s ride uphill on STS-127.
Initial testing concentrated on the adhesive properties between the foam and the tank’s structure in 26 locations in the intertank region. Those initial results showed positive margins.
“TPS-ET-132 Foam Bond Adhesion Verifications: All 26 locations now tested and have adhesion failures only. ET-132 Foam Adhesion: All 26 locations had COHESION failures not adhesion failures,” noted a memo (L2) outlining the good news from the initial testing.
While those areas were being repaired, the pull test results went to the “Noon Board” – a daily meeting between shuttle managers – at the Johnson Space Center (JSC) in Houston.
“11 of the 26 (reapplication of foam) and in trim now on the +Z side. 13 on the -Z side have Conathane applied and (reapplication of foam),” added the memo. “Noon Board today will determine the next course of action and if more pulls are required.”
