NASA's Space Shuttle Endeavour is expected to be launched on 14 November from Kennedy Space Center launch complex 39 pad A for its International Space Station resupply mission STS-126. On 23 October Endeavour was moved from pad B to A. It had been at B to act as a rescue shuttle if the postponed Hubble Space Telescope servicing mission's orbiter Atlantis had launched and been damaged on ascent. In a Shuttle first, Endeavour will use a moving map during STS-126.
