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 [...]

Atlantis’ piggyback ride back to the Kennedy Space Center (KSC) is expected to come to a conclusion between 6pm and 6:30pm at the Shuttle Landing Facility (SLF). Meanwhile, managers have been reviewing the foam loss from STS-125’s External Tank (ET-130) as part of the STS-127 Flight Readiness Review (FRR).

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 [...]

Engineers will carry out the repair on Atlantis’ damaged port radiator over the weekend, as STS-125 pushes ever closer to the launch countdown for the mission to Hubble. Meanwhile, the issue relating to the Forward Reaction Control System (FRCS) F5R thruster issue on Discovery has been cleared on both Atlantis and Endeavour.

No issues are being worked on Atlantis at Pad 39A, as STS-125 continues to proceed towards launch in just over a month’s time. One crucial element for the May 12 launch is the replacement hardware that Atlantis will carry to the Hubble Space Telescope, with several days of mission content simulations taking place next week, [...]

As expected, the Flight Readiness Review (FRR) has cleared Discovery to target a launch at 9:20pm on March 11, following a final review of the Flow Control Valve (FCV) flight rationale. One constraint - relating to the left SRB (Solid Rocket Booster) Range Safety System - will be worked over the weekend.

Shuttle managers have concluded the Delta Flight Readiness Review (FRR) - one of the longest in shuttle history - by failing to approve flight rationale due to concerns with the Flow Control Valves (FCVs). No launch date has been set, but February 27 is no longer the target. Teams will meet again on Wednesday to [...]

Discovery’s processing flow at Pad 39A is continuing in part, in the hope the realigned NET (No Earlier Than) launch date of February 19 for STS-119 will not be further delayed. Minutes from the Agency level Flight Readiness Review (FRR) point to a huge amount of work being undertaken in order to achieve the requested [...]

Pending work on outstanding issues, the Agency level Flight Readiness Review (FRR) have decided to aim for No Earlier Than (NET) February 19 as the STS-119 launch date, based on issues with the Flow Control Valves (FCV). Several items of interest are being looked at, mainly from the standpoint of flight rationale - which is expected to [...]

Following a run of “clean” flights during 2008 - thanks to continued progress in reducing foam liberation from the External Tanks - the Space Shuttle Program (SSP) Flight Readiness Review (FRR) focused on the threat of ice liberation during ascent for 2009’s opening mission, STS-119. This follows a near miss with a large piece of [...]
