ULA launch of U.S. spy satellite delayed, will try again Sunday

The launch of a United Launch Alliance (ULA) Delta IV Heavy rocket has been rescheduled. 

ULA says the mission is delayed due to an issue with the swing arm retraction system.

The launch is now scheduled for 12:10 a.m. EDT, on Sunday, Sept. 27.

ULA is launching a classified spy satellite for the National Reconnaissance Office (NRO) aboard the ULA’s Delta IV Heavy rocket.

The rocket is scheduled to lift off from Launch Complex 37 at Cape Canaveral Air Force Station. 

“This rocket is the largest of the Delta IV family. Its triple-body rocket is formed by mounting three common booster cores together,” ULA said.  

This will be 141st mission for United Launch Alliance and the 29th for the NRO. It is the 385th Delta launch since 1960 and the 12th Delta IV Heavy, according to ULA.
