The weather did not cooperate for the third day in a row as a severe Florida afternoon storm rolled over Cape Canaveral Air Force Station scrubbing the launch of a United Launch Alliance Delta IV carrying three satellites for the U.S. Air Force Space Command. See coverage of the first launch attempt and of the second launch attempt.

The launch team will stand down and take Sunday off then try again late Monday afternoon when drier air is expected to move into the region increasing the chances of good weather at launch time.
