Launch of rocket carrying U.S. spy agency payload called off seconds before liftoff

United Launch Alliance on Saturday called off the Delta IV Heavy rocket launch at Vandenberg Airforce Base in California. The countdown stopped a few seconds before liftoff as the spy satellite remained on its launch pad.


The launch of a massive rocket carrying out a mission for the U.S. agency responsible for spy satellites was called off just seconds ahead of liftoff on Saturday.

United Launch Alliance, a contractor for the U.S. National Reconnaissance Office (NRO), was expected to launch a Delta IV Heavy rocket carrying the NROL-71 mission from Vandenberg Air Force Base in California on Saturday evening.

The launch was initially delayed, then called off about 7.5 seconds before liftoff. The company said there was “an unexpected condition during terminal count.”

“The team is currently reviewing all data and will determine the path forward. A new launch date will be provided when available,” ULA said.

A previous launch attempt was aborted on Friday due to an issue with a communication link between the control centre and launch site.
