Preparations
After its most recent mission (STS-123), Endeavour was taken to the Orbiter Processing Facility for routine maintenance. Following the maintenance, Endeavour was on stand-by for STS-326 which would have been flown in the case that STS-124 would not have been able to return to Earth safely. Stacking of the solid rocket boosters (SRB) began on 11 July 2008. One month later, the external tank arrived at KSC and was mated with the SRBs on 29 August 2008. Endeavour joined the stack on 12 September 2008 and was rolled out to Pad 39B one week later.
Since STS-126 launched before STS-125, Atlantis was rolled back to the VAB on 20 October, and Endeavour rolled around to Launch Pad 39A on 23 October. When it was time to launch STS-125, Atlantis rolled out to pad 39A.

Famous quotes containing the word preparations:
“The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.”
—Marcus Tullius Cicero (106–43 B.C.)
“Whatever may be the reason, whether it was that Hitler thought he might get away with what he had got without fighting for it, or whether it was that after all the preparations were not sufficiently complete—however, one thing is certain: he missed the bus.”
—Neville Chamberlain (1869–1940)
“In all the important preparations of the mind she was complete; being prepared for matrimony by an hatred of home, restraint, and tranquillity; by the misery of disappointed affection, and contempt of the man she was to marry. The rest might wait. The preparations of new carriages and furniture might wait for London and the spring, when her own taste could have fairer play.”
—Jane Austen (1775–1817)
