STS-133: Engine placement order altered for Discovery
Two of Discovery’s Space Shuttle Main Engines (SSMEs) will be re-installed in opposite positions, following their removal to allow for work to take place on Main Engine #1 (ME-1). The change to the engine order will allow for two SSMEs to return to Discovery’s aft next week, after the troublesome ME-1 turbo pump is sent…

Discovery’s SSMEs to be removed on Thursday due to LPOTP issue
Engineers are preparing to remove Discovery’s three Space Shuttle Main Engines (SSMEs) on Thursday, after SSME 1’s Low Pressure Oxidizer Turbo Pump (LPOTP) failed torque checks. No schedule impact will be suffered as a result of back-stepping in the flow, due to the six week slip to STS-133’s launch date caused by payload requirements. STS-133…

Boundary Layer Transition height increase and addition noted for STS-134
As NASA and Space Shuttle Program Managers continue to narrow down options for the final two missions on the flight manifest, preparations and modifications for/to Orbiters Discovery and Endeavour are continuing in their respective Orbiter Processing Facilities (OPFs) at the Kennedy Space Center – most notably the process to approve a new Boundary Layer Transition…

STS-133 stack takes shape as Discovery prepares for summer in her OPF
Engineers are working on finalizing mating operations on STS-133’s External Tank and Solid Rocket Boosters (SRBs), although it will be at least a couple of months until they are joined by Discovery. The veteran orbiter has welcomed her three Space Shuttle Main Engines (SSMEs), as the flow continues to push way ahead of the realigned…

Shuttle fleet deep in processing for their new launch dates
While the three shuttle orbiters continue to enjoy nominal processing flows, managers are continuing to evaluate the exact launch date targets for the upcoming missions. Those launch dates have slipped at a program level, with STS-133’s mission to the International Space Station (ISS) now baselined for No Earlier Than (NET) late October, slipping STS-134 to February/March, 2011, with the potential for STS-135 to launch…

STS-133: Three Flight Days and two EVAs added to Discovery’s mission
As NASA managers continue to work through evaluations on the remaining three Space Shuttle missions – STS-133/ULF-5, STS-134/ULF-6, and STS-335 (Launch On Need for STS-134) – a reconfiguration of the launch manifest has begun via the June 10th PRCB (Program Requirements Control Board) decision to official increase the mission duration and content of the final…
