Shuttlestart - beinahe!

Der langersehnte Start eines Space Shuttles

Shuttle Endeavour – the youngest orbiter in the fleet – was preparing for her final hours prior to launch, after the Mission Management Team (MMT) met to approve the tanking of ET-122.  However, several issues popped up in the count, most notably with an OMS tank issue, which was then resolved, prior to a heater issue on Auxiliary Power Unit (APU) 1 – which has resulted in a several day scrub.
