Endeavour was then be loaded onto the Orbiter Transporter System (OTS) for the short journey to the VAB, ahead of S0004 Orbiter\/ET mating operations.<\/p>\n
\u201cCall to Stations for S0004 Orbiter\/ET mate occurred at 06:00 (local),\u201d added Friday processing information. \u201cFirst motion for rollover to the VAB is expected at 07:00 (confirmed as almost exactly on schedule). Weekend work: S0004 Orbiter\/ET mate and preps for S0008, Shuttle interface test.\u201d<\/p>\n
Following a week of mating and interface operations in the VAB, Endeavour will be rolled out to Pad 39B, with the ability to launch within seven days \u2013 should Atlantis\u2019 crew require rescue during STS-125.<\/p>\n
STS-400:<\/p>\n
The unique nature of Endeavour\u2019s rescue roll, known as STS-400 LON, is due to the lack of \u201csafe haven\u201d that is provided by the International Space Station (ISS) on all other shuttle missions.<\/p>\n

Managers had considered a single pad option, which would have involved utilizing Pad 39A for both STS-125\u2019s launch, and \u2013 if required \u2013 an accelerated pad flow for STS-400.<\/p>\nHowever, due to the on-going schedule\/funding problems with the Constellation Program (CxP), Ares I-X\u2019s subsequent delays to its test launch allowed the Space Shuttle Program (SSP) to continue to utilize Pad 39B for STS-400, while a level of Ares modifications \u2013 including construction of the three 600 foot Lightning Towers (over 500mb of hi res images from blueprints to completion on L2) \u2013 were completed.<\/p>\n
Endeavour will be protected by two of the new lightning towers during her stay at Pad 39B, following the removal of the mast that was previously located at the top of the Fixed Service Structure (FSS), ahead of Ares I-X\u2019s eventual test launch.<\/p>\n
STS-127:<\/p>\n
Once stood down from STS-400 requirements, Endeavour will be rolled off Pad 39B, transported down the crawlerway to the fork that splits off to Pad 39A, before being rolled up on to the vacated pad. This was previously seen ahead of STS-126, following Atlantis\u2019 roll back to the VAB due to a mission delay caused by an on orbit issue with the Hubble Space Telescope.<\/p>\n

Endeavour will then be processed for her primary mission, STS-127, which includes the delivery of the Japanese Experiment Module \u2013 Exposed Facility (JEM-EF) and the Japanese Experiment Logistics Module \u2013 Exposed Section (ELM-ES) as well as the Integrated Cargo Carrier \u2013 Vertical Light Deployable (ICC-VLD).<\/p>\nAttached to the ICC-VLD will be six P6 truss batteries (which will be part of the P6 battery R&R activities during one of the mission\u2019s EVAs), a Linear Drive Unit, Pump Module #2, and a Space to Ground Antennae \u2013 all of which will be transferred to ESP-3 (External Stowage Platform-3) during an EVA.<\/p>\n
In addition to these primary payloads, Endeavour will fly with DRAGONSAT (Dual RF Autonomous GPS On-Orbit Navigator Satellite), the MAUI (Maui Analysis of Upper-Atmospheric Injections), ANDE-2 (Atmospheric Neutral Density Experiment-2), SEITE (Shuttle Engine Ion Turbulence Experiment), and SIMPLEX (Shuttle Ionospheric Modification with Pulsed Local Exhaust).<\/p>\n
The mission \u2013 working to a NET (No Earlier Than) June 13 launch date \u2013 is currently under a recommendation of being increased to 16 days (16+0+0) in duration, due to Shuttle Crew Scheduling Constraints (SCSC) rules relating to off duty time during flight.<\/p>\n

As part of the dual flow for STS-125, Endeavour has rolled over from her Orbiter Processing Facility (OPF-2) to the Vehicle Assembly Building (VAB), where she will be mated with External Tank ET-131 over the Easter weekend.
