The loss of a HIM would not have endangered Discovery, due to fail safe\/redundancy and the ability to scrub, added to the information pointing to the failure happened at the exact moment Discovery started to lift off the pad. However, it did lead to a long night for the \u2018pad rats\u2019 at KSC. <\/font><\/p>\n \u2018One of the power supplies on the MLP failed at T-0 and this made for a little bit of a long night for the people doing post-launch securing, which is plenty hazardous,\u2019 noted one source. \u2018It would\u2019ve been a bad night indeed (for the facility, at least) had they been lost.\u2019 <\/font><\/p>\n Another source also noted it took several hours longer to safe the pad due to the power anomaly: \u2018Some of the HIMs are new and utilized for first time for this launch. It was a longer night for the safing teams, approx. 4.5 hours before Engineering could get HIMs needed for ordnance safing powered up, and teams on pad for safing activities.\u2019 <\/font><\/p>\n Early information on what was the source of the fault points to an electrical fault in the Payload Changeout Room (PCR) at the pad, which caused a cascade throughout some of the pad and MLP systems. <\/font><\/p>\n \u2018The fault was power supply in the PCR (Payload Changeout Room), which took a dump, resulting in a cascade to racks in the MLP,\u2019 noted source information. \u2018The MLP is now fixed.\u2019 <\/p>\n The weekend of evaluations on Pad 39A, classed as \u2018PAD A Power Outage Testing,\u2019 was deemed a success. 39A will carry out the remaining shuttle launches, bar 39B\u2019s final role as the pad that will host LON-326 \u2013 the rescue mission contingency for the launch of STS-125 to the Hubble Space Telescope in September 2008. The pad will then be officially handed over to Constellation for modification work ahead of the Ares I-1R test flight in 2009.<\/font><\/p>\n \u2018A complete power outage test was conducted at Pad A on Saturday morning,\u2019 noted a NASA Ops report. \u2018The primary purpose of this test is INCS validation. Call to stations was scheduled for 0600 hrs, with the outage occurring at daylight, approx. 0715 hrs, and lasted approx. 15 minutes. All three medium voltage power feeders (518, 612, and 606) were taken down, then restored sequentially.<\/font><\/p>\n \u2018After successful completion of the power out test, an outage was carried out on UPS 10 & 10A and 11 &11A for approximately 10 minutes on each UPS. The purpose of this test is to verify the output of the UPS power system in event of a loss of UPS power in support of the INCS modification. <\/p>\n \u2018The driver for this test is the power anomaly experienced directly after STS-116 launch at Pad B in December.\u2019 <\/p>\n The results of the tests proved there aren\u2019t any outstanding issues with Pad 39A, as power was restored successfully, following the powerdowns. <\/font><\/p>\n \u2018Part 1: Power to feeders 518, 612, and 606 was brought down at 0718 hrs and restored in sequence by 0744 hrs with no major issues,\u2019 added the Ops report. \u2018Part 2: UPS 10\/10A and 11\/11A were brought down in sequence starting at 0804 hrs. All UPS were restored by 0838 hrs with no major issues.\u2019<\/font><\/p>\n <\/font>Pad 39A is set to host Atlantis from mid-February, ahead of the NET (No Earlier Than) March 15.<\/font><\/p>\n **INFINITY: 10 minute STS MUSIC VIDEO**<\/font><\/em><\/font> \u2013 United Space Alliance and NASA engineers have successfully carried out a power outage test on Pad 39A, following a large scale power loss that occurred just as shuttle Discovery was leaving the Pad 39B on STS-116 last December.
