Discovery crew seated & ready to go.  NASA/KSC

NASA's second try for the liftoff of the Discovery Shuttle is scheduled for today, in less than two hours.  The crew has been loaded into the shuttle and workers are preparing to close the pressurized, double-sealed hatch, having given the vehicle interior one last "once-over."  You of course can watch everything live online on NASA TV (Open TV with RealPlayer or Windows Media Player), and if anything goes wrong you''ll be the first to hear it.
