Space shuttle Endeavour’s external fuel tank was filled with more than 500,000 gallons of super cold liquid oxygen and liquid hydrogen began at 11:36 p.m. EDT and the count down restarted at T-6 hours following a two-hour built in hold. 


Shuttle Weather Officer Kathy Winters continues to predict a 70 percent chance of favorable weather for today’s launch. The only concerns are for low cloud ceilings and high crosswinds at the Shuttle Landing Facility. 


Endeavour’s launch is therefore on target for 8:56 am. EDT. Shuttle Launch Director Mike Leinbach said the countdown is going extremely well and the team is ready to go.
