The Ambition of a Moon Launch?

Nassa sources are telling m b c news that the eight 33 a m scheduled launch is probably not going to happen. It is slipping because the pre flight check list is so complicated and because they're falling behind. Currently, they're having some trouble gettng hydrogen to flow properly through the third of four engines on board. If it doesn't fly to day, it could fly friday, but weathers must be bad then. So it's not looking great for a launch right now.
