Positive news as MSFC testing finds faults with connector

Mon, 01/14/2008 - 12:19
Weekend testing of the removed ET-125 LH2 Feed-through connector resulted in "circuit instability" on two ECO (Engine Cut Off) sensors during LH2 test runs at the Marshall Space Flight Center (MSFC). While testing will continue, these opening results add confidence to the initial data that pointed to the "External Plug / Feed Through Receptacle Pin Contacts" as the cause of the ECO system anomalies during the two STS-122 launch attempts and subsequent tanking test.

STS-122: Engineers install ET-125's modified connector

Sun, 01/13/2008 - 03:03
United Space Alliance (USA) and Michoud Assembly Facility (MAF) engineers have installed the replacement external LH2 Feed-through connector inside Atlantis' ET-125, marking a key milestone ahead of Atlantis' NET (No Earlier Than) February 7 launch. The modified element of hardware is the "most likely" solution to the Engine Cut Off (ECO) system anomalies that have delayed the mission - as tests continue at the Marshall Space Flight Center (MSFC).

PRCB plan STS-122 for NET Feb 7 - three launches in 10-11 weeks

Thu, 01/10/2008 - 12:32
Thursday's Program Requirements Control Board (PRCB) meeting has concluded with a decision on a forward plan that will allow for three missions in the space of around 10 weeks. Managers discussed the current status of testing on the external LH2 Feed-through connector troubleshooting, and decided against conducting a tanking test ahead of the launch of STS-122, which is now tracking a NET (No Earlier Than) February 7 launch date.

STS-122: Hale calls for patience and positivity ahead of crucial period

Wed, 01/09/2008 - 05:18
Shuttle manager Wayne Hale has called for patience, as engineers focus on solving STS-122's LH2 Feed-through connector problems. A crucial set of test results are being collated from the Marshall Space Flight Center (MSFC) - which will provide the basis for the go-ahead for the installation of a replacement connector into ET-125 later this week. At the same time, the program is already working towards rolling out Endeavour - ahead of STS-123 - pre-empting a run of six missions in 2008.

New issue found on Atlantis' removed ET Feed-through connector

Mon, 01/07/2008 - 21:21
A new issue with Atlantis' External Tank LH2 Feed-through connector hardware will require further investigation, after cracks were found on the glass seal below the pins on ET-125's removed external connector. At present, engineers do not believe it is related to the Engine Cut Off (ECO) system anomalies, as the process begins at the pad to install a replacement Feed-through connector system into the tank, in time to allow STS-122 to launch in early February.

STS-122: Real launch date is early February - Koerner

Sun, 01/06/2008 - 18:01
While some level of confusion in the media was caused by deputy shuttle manager John Shannon's January 24 reference last week, STS-122 will "definitely" get another "work to" launch date in around a week's time. NASA, United Space Alliance and Lockheed Martin schedules show STS-122 is currently NET (No Earlier Than) February 2, leading to Flight Director Cathy Koerner to send out a memo of clarification that the launch is tracking the February timeline - not January.

Atlantis' ATVC replacement adds strain to launch date target

Fri, 01/04/2008 - 16:18
While engineers continue to move forward with preparations for the installation of replacement external LH2 Feed-through connector hardware on ET-125, another issue may overlap the tank repair schedule. The problem relates to the ATVC (Ascent Thrust Vector Control) - specific to the commanding of the Right Solid Rocket Booster (SRB) Rock Actuator. The unit will be replaced over the weekend, although documentation shows Sunday as the deadline for replacing the unit, in order to make the February 2 launch date target for STS-122.

PRCB draw up their forward plan - STS-122 NET launch date plan

Thu, 01/03/2008 - 05:57
Shuttle managers have concluded their meeting over the latest status of the troubleshooting efforts on ET-125, which is to receive new external LH2 Feed-through connector hardware, due to arrive on Friday. The PRCB was presented with a forward plan that shows the new NET (No Earlier Than) launch date as February 8 - should they decide to conduct a tanking test. Without the test, they could aim for February 2. These date options are "expected" - while a protected January 24 option is deemed unlikely.

ET-125 Connector removed to kick start major STS-122 repair effort

Sat, 12/29/2007 - 11:13
Engineers have removed the external LH2 Feed-through connector from ET-125, beginning the next stage of the major troubleshooting that has caused the delay to STS-122's launch. Moving forward with repair Option A, engineers hope that subsequent testing will confirm the ECO (Engine Cut Off) system anomaly is specific to the external elements of the connector, allowing work to be completed at the pad, thus avoiding rollback.

STS-126 set to carry out special reentry experiment

Thu, 12/27/2007 - 11:16
The STS-126 mission will resume ISS operations after a break for STS-125's flight to the Hubble Space Telescope, but one of the newest additions to the mission plan won't take place until reentry. The mission's Program Freeze Point was overviewed at the PRCB (Program Requirements Control Board) meeting earlier this month, where a Boundary Layer Transition (BLT) Detailed Test Objective (DTO) was proposed.

PRCB debates STS-122 options - includes rollback and tank swap

Thu, 12/27/2007 - 08:33
Two options were debated by the all-powerful PRCB (Program Requirements Control Board) meeting, one of which will allow Atlantis to aim for a late January - or more likely - early Febuary launch date, the other involving rollback. Currently, "Option A" appears to have the support of shuttle management, which will involve the soldering of the LH2 Feed-through connector pins. "Option B" involves rollback and a tank swap with ET-126.
