Shuttle Endeavour has completed her rollout to 39B, where she will be put through a part flow as the STS-400 LON (Launch On Need) support for Atlantis’ STS-125 mission. During this flow, engineers will test the alignment procedures with the Ground Umbilical Carrier Plate (GUCP) – following the leak during STS-119′s opening launch attempt.

Engineers are working on a problem observed with Atlantis’ External Tank (ET-127), which will likely require the removal and replacement of a valve.Mold impressions of the damaged GH2 two inch disconnect valve were taken overnight, with meetings taking place on Friday to discuss a forward plan. However, should R&R be required, work is expected to [...]
