Testing of connector exhibited same characteristics seen during the countdown. Data analysis will be done to pinpoint location of break. Working on flight rationale and root cause,\u2019 noted engineering information.<\/p>\n \u2018New connector installed on STS-122 vehicle. Preliminary leak checks are complete; working on closeout and refoaming. Cold temperatures at KSC have slowed down work but should not impact 2\/7 launch date.\u2019 <\/p>\n Such is the expanse of data being gathered on pinpointing the root cause, testing may continue past STS-122\u2019s launch, though shuttle management are understandably buoyant that the Marshall testing has \u2013 once again \u2013 proved their expects right, as they beginning building flight rationale for proceeding with the next stage of the forward plan towards launch. <\/p>\n \u2018While the data from the tests is still in review, reports are that all circuit anomalies experienced during our testing were representative of anomalies seeing during the STS-122 scrubs and tanking test. <\/p>\n \u2018That was a great day, and we in fact have the problem hardware in hand. In other words, most believe these failures represent the \u2018smoking gun\u2019 that points to the external portion of the connector as the failed hardware. These test results will provide much of the flight rationale for the feedthru connector R&R work.\u2019<\/p>\n The low temperatures at KSC did delay the start of closeout of the work site on ET-125, following the weekend installation of the replacement connector hardware. However, the cure time schedule has some in-built flexibility, thus February 7 remains the viable launch date. <\/p>\n \u2018Due to low temperatures on 1st shift yesterday primer applications were delayed again,\u2019 noted processing information on Wednesday. \u2018Modifications to the enclosure around the feedthru plate were put in place yesterday to enhance the ability to maintain adequate temperatures to enable TPS applications and curing through the night, subsequent temperatures and humidity have been maintained successfully.<\/p>\n \u2018Conathane application was completed and in cure at 1645L. PDL foam pours began late on 3rd shift this morning (Wednesday) and foam cure is in work. ECO sensor wiring used during the tanking test is being removed and will continue through 2nd shift Wednesday.\u2019<\/p>\n Though not believed to be a concern, tests are continuing on the observation of cracking of the glass seal, spotted on ET-125\u2019s connector. Testing \u2013 which included an old X-33 connector \u2013 showed there is no concern on the possibility LH2 could leak through the cracks \u2013 which was the main safety issue, though engineers are continuing to finalize their data. <\/p>\n \u2018Glass cracks on connector seal have no affect on failure mechanism based on analysis. Engineering qual program is being established for those with cracks (STS-122, -123) and working on longer program to qual cracks generically. Preliminary test showed no leaks and program will test for crack growth.\u2019 <\/p>\n SARJ Latest:<\/u><\/em><\/p>\n \u2018Although STS-122 has slipped to early February, the Space Shuttle Program has confidence that the ET feed through connector modification in work will not only resolve the problems with this tank, but may well be the solution to the recurring problems with the ECO system,\u2019 noted manager Paul Hill. \u2018If so, it is well worth the wait to get this headache out of the way of all other Shuttle flights. <\/p>\n \u2018ISS has challenges of its own with the starboard SARJ and one of the starboard beta gimbals, each of which promises more EVA time for repairs necessary to restore full capability and support the remaining modules, experiment racks and a six person crew.\u2019<\/p>\n Four options were discussed this week on a forward plan for a resolution for the SARJ, though a root cause is still uncertain. The solution won\u2019t be implemented into Atlantis\u2019 mission, though managers are looking to send up some of the required tools in advance \u2013 including a grease gun.<\/p>\n \u2018ISS Program requested additional items on STS-122 for a crack repair technique using the caulk gun filled with grease cartridges to lubricate to the SARJ ring,\u2019 noted Stand-up report information. \u2018This will be added to the manifest of STS-122.\u2019 <\/p>\n This points towards a possible acceptance of \u2018option 4,\u2019 which would involve EVAs to clean, lubricate and then run the SARJ. Other work will be involved in what will ultimately be an expansive forward plan. <\/p>\n \u2018Regarding the latest on SARJ, the SARJ Team recommended and obtained approval to plan on a NET ULF-2 Outboard Ops Mode R&R,\u2019 noted an 8th Floor report. <\/p>\n \u2018This decision was based on a performance analysis, the lack of an identified root cause, and the ability to perform limited directed position and autotrack to get us past any pinch points for mission and stage activities. There remains forward work to determine if we 1) run the SARJ as-is, 2) clean and run, 3) lubricate and run, or 4) clean, lube and run. <\/p>\n \u2018The SSPCB also approved the recommendation to remove the TBAs manifested for 1J\/A. These will remain on the ground in the event our root cause analysis determines that adjustments\/modifications are required.\u2019<\/p>\n In addition to the work that could be incorporated into future shuttle missions, ISS managers are also looking at potential work that can be added into stage work on the ISS.<\/p>\n \u2018Expedition 18 asked to assess the impact of adding SARJ EVA\u00e2\u20ac\u2122s to the increment. Initial assessment is that if the additional training starts in the Jan\/Feb trip the crew loading will spike up to yellow,\u2019 noted an ISS memo. <\/p>\n \u2018If the training starts in April the crew loading will spike just below red. The Backup crew would be Yellow. The assessment was made with the assumption that there would be no additional time in the US and that the US training requirements would be assessed.\u2019<\/p>\n Regardless of the issues with the delay to STS-122, and the continuing SARJ evaluations, managers remain buoyant on the forward plans, as they prepare for six missions and a major increase to the size and operation of the orbital outpost.<\/p>\n \u2018On the brighter side, one of the ISS team\u2019s leading problems each week is to continue bringing forward more tasks from later in the year for this crew to do since they keep plowing through the work faster than we can give it to them,\u2019 added Paul Hill. <\/p>\n \u2018The fact is, hurdles or not, ISS is humming along beautifully with ESA soon to be an active partner in real time and JAXA a month behind them. <\/p>\n \u2018Likewise, look back on the ISS assembly made possible by an amazing string of Shuttle flights from Fall 2006 through STS-120. We are set to end the year with hardware onboard ISS to support six crew members and a repaired Hubble Space Telescope.\u2019 **STARLIGHT: NEW STS-117 MISSION REVIEW MUSIC VIDEO** \u2013 STS-118 and STS-120 Mission review video also available.<\/font><\/em><\/font> <\/em><\/font><\/p>\n **ROCK YOU LIKE A HURRICANE: STS-117 MISSION REVIEW MUSIC VIDEO \u2013 AS SEEN BY THE STS-117 CREW!!**<\/font> -.

More test runs on the connector have been conducted at the Marshall Space Flight Center (MSFC), as STS-122 continues to return back into a launch posture for February 7. <\/p>\n
\u2018During the LH2 test, ECO #4 failed in a repeat fashion, and ECO #2 showed a repeat \u2018noisy\u2019 condition, similar to the previous launch count down signatures. <\/p>\n
With the \u2018headache\u2019 of the STS-122 ECO system issues soon to become a thing of the past, NASA managers are looking to find a solution to the starboard SARJ on the ISS \u2013 which is out of service, following findings that 1505 Nitride material is being ground away from the race ring.<\/p>\n
