And count them...two space shuttles out on the launch pads at Kennedy Space Center. Next month, Atlantis will launch to repair and upgrade the Hubble telescope. Endeavor is standing by in case Atlantis gets into any trouble. Because of the telescope's orbit Atlantis would not be able to reach the International Space Station in an emergency. For every shuttle mission since Columbia, there has been a contingency plan in place to allow another shuttle to be launched if needed to rescue a stranded crew.
