Published by NASASpaceflight on 08/28/2023
United Launch Alliance (ULA) has called off its Atlas V launch of the classified NROL-107 Silent Barker mission set for Tuesday. ULA noted that “out of an abundance of caution for personnel safety, a critical national security payload, and the approaching Tropical Storm Idalia,” the decision was made to return the rocket and payload to the vertical integration facility (VIF) at SLC-41.
