It has to be a crushing disappointment to be SO ready for such a
pivotal event... and then have to delay one's aspirations for the
better part of a week... but alas, that is the situation facing the
crew of STS-127. As noted previously, NASA has had to postpone
space shuttle Endeavour's launch to the International Space
Station, Saturday, because of a leak associated with the gaseous
hydrogen venting system outside the shuttle’s external fuel
tank.
