CAPE CANAVERAL, Fla — The flight of a United Launch Alliance (ULA ) Atlas V 551 rocket and its payload of the fourth satellite for the Mobile User Objective System (MUOS-4) – has been delayed due to what is currently Tropical Storm Erika. At present, the mission is not expected to take to the skies any earlier than Sept. 2.

The announcement, made late in the day on Friday, Aug. 28, came just hours after a teleconference held with the key organizations involved with the planned flight. During the hour-long exchange mission managers noted that they were closely following the conditions down in the Caribbean.

Florida’s Governor, Rick Stott, declared a State of Emergency after the storm had caused the deaths of at least 20 people in Dominica after it had passed over the tiny Caribbean island.
