ALL related handbooks, from Final Flight Plan to EVA Presentations (550mb of 115 presentations downloadable)**<\/font>.<\/p>\n <\/em><\/font> Follow the above live update thread for live updates from internal NASA reports.<\/p>\n Current News Roundup<\/em><\/u><\/p>\n \u2018Launch scrubbed for 24 hours due to fuel cell problem,\u2019 noted the official document being sent around NASA officials. \u2018Plan is to meet w\/ vendor in the morning.\u2019<\/p>\n While the next attempt will take place on Thursday, a replacement of the fuel cell would rule out the current 6th to 8th launch window. A Mission Management Team (MMT) meeting will take place at midday to evaluate. <\/p>\n All three fuel cells need to be working to allow for a launch to proceed. <\/p>\n \u2018There was a current spike on AC1 \u00c3\u2013A of approximately 0.9 amps. This was followed by an increased continuous load of 0.11 and 0.07 amps on phases B and C, respectively. <\/p>\n \u2018Phase A then dropped to approximately 0.5 amps below the previous run current. FC 1 is currently connected to MNA in order to bring up the operating temperature. This will place the FC in a better condition if KSC decides to stop the pump package to evaluate the coolant pump. <\/p>\n \u2018KSC opened an (note of problem). Meeting at 0200 (7am UK time): No go for launch today. No confidence in phase B and C.\u2019<\/p>\n The coolant pump is a motor and requires 3 phases of AC to work properly <\/b>(although 2 phases may or may not work in some cases<\/b>). The higher currents on that phase <\/b>(A of AC1<\/b>) may indicate that the pump is the problem. <\/p>\n It is likley engineers will take the pump off line and see if the indications on AC1 change, this will help narrow down the origin of the problem.<\/p>\n Other issues noted on the report included less minor issues \u2013 all of which will not affect another attempt tomorrow, if possible. <\/p>\n \u2018Ascension Island down \u2013 ETRO 1600 GMT, 7 September \u2013 They have a computer difficulty which requires some hardware. There was some word about trying to get up for the next couple of passes, but the official ETRO remains the same.<\/p>\n <\/font><\/p>\n <\/font>\u2018Post Insertion Checklist \u2013 Shaded pictorials on pages 014, 015, A11 do not have panels for OV-104. Non-shaded, boxed switch configurations are correct. Crew has been informed.\u2019<\/p>\n NASA has a launch window at the end of September (Sept. 24), if required. Documents on L2 show the opportunity exists, should the lighting restriction on ET photography be dropped. The next \u2018lighted\u2019 window opens at the end of October. <\/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><\/font><\/p>\n","protected":false},"excerpt":{"rendered":" NASA have been forced to scrub Wednesday\u2019s launch of Shuttle Atlantis, following a \u201clost phase A on the FC coolant pump motor\u201d on Fuel Cell 1.
