One was to proceed with 3\/4 ECO sensors, the other to scrub for 24 hours and attempt to launch on Saturday. ET have noted they are go for launch, which will be a critical element for the evaluations.<\/p>\n As per Launch Commit Criteria (LLC) rules, newly expanded on at a recent PRCB meeting that was chaired by Shuttle manager Wayne Hale, the correct procedure should be to scrub for 24 hours.<\/p>\n However, it is now believed that the ECOs are not specifically at fault, with sources noting it is more likely to be an indication that the Point Sensor Box (PSB) on the orbiter \u2013 and more so the circuits inbetween \u2013 are at fault.<\/p>\n When it came down to the poll of all centers, the MMT showed a majority wanted to fly today. <\/p>\n \u2018Flight Crew systems was the one decenting vote,\u2019 noted a NASA memo describing the decision.<\/p>\n \u2018However MPS integration of JSC engineering did not want to accept the LCC waiver, hence they were no-go. <\/p>\n \u2018Subsequent to the poll, the MMT chairman opted to detank and try again tomorrow.\u2019<\/p>\n Early reactions to the scrub have been positive, noting the obvious lack of \u2018go fever\u2019 which NASA has been accused off in the past.<\/p>\n The decision to comply with LCC launch rules has been applauded.<\/font><\/p>\n A number of other issues have been noted this morning, refer to the live update thread for information. <\/p>\n One such issue includes the Tyvek cover on thruster F3L, with the concern being if any water gets into the thruster, it could freeze and block.<\/p>\n **DETERMINED STS-115 MUSIC VIDEO**<\/em> \u2013 <\/em><\/font> **NASASpaceflight.com Job Opportunities**<\/font> <\/font><\/em><\/p>\n <\/u><\/p>\n <\/p>\n <\/font><\/p>\n <\/font><\/font><\/p>\n","protected":false},"excerpt":{"rendered":" A LH2 ECO (Engine Cut Off) #3 sensor failed during tanking, but External Tank managers have decided recommend that NASA proceeds with the launch of Shuttle Atlantis on STS-115.
