NASA announced that the launch of the Space Shuttle Endeavour has been delayed again due to weather. The next launch attempt will be on Wednesday July 15 at 18:03 Eastern time (22:03 GMT). The weather looks better then, with a predicted 60% chance of favorable launch conditions.
If they have to delay one more day, then the launch will occur on the 40th anniversary of the launch of Apollo 11. Just so's you know.
