United Launch Alliance (ULA) will wait one more day to fly its Mighty Atlas on a highly secretive mission for the National Reconnaissance Office, following a technical issue which cropped up shortly after the vehicle completed its rollout from the Vertical Integration Facility (VIF) to the Space Launch Complex (SLC)-41 pad surface at Cape Canaveral Air Force Station, Fla., on Monday.
