CAPE CANAVERAL, Fla., Sept. 29, 2020 ULA PR) – 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.

Launch is now scheduled for 11:54 p.m. EDT on Wed., Sept. 30, 2020.
