STS-127′s External Tank (ET-131) has completed a tanking test on the realigned Ground Umbilical Carrier Plate (GUCP) and a two-part seal, with no leaks detected. As a result, NASA is officially a go for a launch attempt of Endeavour on July 11.

Managers have set next Wednesday morning for a full-up tanking test of External Tank ET-131 to test a potential solution to the leaking Ground Umbilical Carrier Plate (GUCP). The leading candidate for the cause of the leaks is believed to be related to the External Tank Carrier Assembly (ETCA) mounts, a problem engineers had documented [...]

Endeavour will launch only when engineers are happy they have a full understanding of the Ground Umbilical Carrier Plate (GUCP) leak, even if that means slipping STS-127 past the current July 11 NET (No Earlier Than) launch target. A troubleshooting plan is currently being drawn up – which is understood to include a tanking test [...]

STS-127 has been scrubbed for the second time due to another leak at the Ground Umbilical Carrier Plate (GUCP). The leak, first registered as within an acceptable range, before rising to breach the four percent (40,000PPM) limits, appears to point to a different issue with the hydrogen vent system. Endeavour will now have to wait until NET (No Earlier Than) [...]

Endeavour has won the right to make a launch attempt on June 17 (Wednesday), following NASA discussions relating to the schedule priorities of the Eastern Range. The decision was made easier thanks to good progress on replacing hardware on External Tank ET-131′s Ground Umbilical Carrier Plate (GUCP), as engineers work around the clock to “safely [...]

In a similar event to STS-119′s scrub, Endeavour’s launch has been delayed due to a significant leak registered in the region of the Ground Umbilical Carrier Plate (GUCP). Engineers will dismantle the troublesome hardware at the pad, with the aim to attempt a single launch opportunity on June 17.

With Endeavour’s June 13 launch to the ISS now counting down, engineers are continuing to work towards the safe flight of the fleet’s youngest orbiter and her crew. To aide in this effort, the Orbiter Project Office (OPO) examined the flight performance of STS-126 (Endeavour) and STS-125 (Atlantis) – the previous vehicle flight and previous program [...]

Atlantis has returned to Orbiter Processing Facility (OPF-1) in preparation for her flow towards the STS-129 mission to the International Space Station (ISS). Marking a busy period for the fleet, Discovery is receiving her SSMEs (Space Shuttle Main Engines) for STS-128, while Endeavour’s SSMEs are being evaluated – after corrosion/contamination was seen on tubing associated [...]

NASA officials have cleared Space Shuttle Endeavour for launch on June 13 at 7:17a.m. This mission, the STS-127/2J/A flight, will complete assembly of the Japanese Kibo Laboratory complex during the 16-day journey to space. With this approval for flight comes one of the final steps of flight rationale for Endeavour’s Reusable Solid Rocket Motors (RSRMs) [...]

Atlantis is finally home after a cross-country trip on top of a Shuttle Carrier Aircraft (SCA) and will now be prepared for rollback to her Orbiter Processing Facility (OPF). Meanwhile, Endeavour’s preparations for launch head into another milestone on Wednesday, when managers meet at the Agency level Flight Readiness Review (FRR), which will set the [...]

The high tempo pace of shuttle processing continues through the weekend and earlier into next week, with Atlantis’ departure from California on top of the Shuttle Carrier Aircraft (SCA) set for Monday and Endeavour’s pad swap on Sunday morning. Endeavour will be arriving at a Pad 39A that has undergone several repairs, following damage sustained during [...]

Endeavour remains on track for the setting of a June 13 or 14 launch date at next week’s Agency level Flight Readiness Review (FRR), despite the requirement for additional SSP (Space Shuttle Program) level evaluations. Several factors, including Atlantis’ In Flight Anomalies (IFAs) – notably the Aerosurface Servoamplifer (ASA) channel 1 fault – are still up [...]

With STS-125 safely completed, NASA is turning its attention towards the June 13 launch of Endeavour to the International Space Station. Particularly, the Mission Operations Directive (MOD) – which conducted their Flight Readiness Review (FRR) for STS-127 last week – paid special attention to “New Operations” that will be a part of Endeavour’s 16-day flight [...]

Atlantis has landed at Edwards Air Force Base on EOM+2 (End Of Mission plus two days), after Entry Flight Director Norm Knight decided the weather at the Kennedy Space Center had failed to improve to acceptable levels. Atlantis will return to KSC on top of a Shuttle Carrier Aircraft (SCA) just a few weeks ahead of [...]

Following the early wave off of two landing opportunities at the Kennedy Space Center (KSC) on Friday, Atlantis and her STS-125 switch their attentions to four opportunities on Saturday, which includes two options for landing at Edwards Air Force Base. Meanwhile, Endeavour is being prepared for her move to Pad 39A ahead of STS-127, pending repairs to [...]
