The launch of the United Launch Alliance Delta IV Heavy NROL-44 mission has been scrubbed.

The local weather resulted in a significant delay to pre-launch preparations including the roll of the Mobile Service Tower (MST).

When the MST roll began we discovered a hydraulic leak in the ground system required to move the tower which needs further evaluation.

Subsequent weather will prevent the team from moving forward with tonight’s attempt.
