Scrubbed Just 7.5 Seconds Before Liftoff ... ULA's Delta IV Launch was Ready or Not for NROL-71 Mission


(Vandenberg Air Force Base, California, December 8, 2018) – The launch of a United Launch Alliance Delta IV Heavy carrying the NROL-71 mission for the National Reconnaissance Office was scrubbed today due to an unexpected condition during terminal count at approximately 7.5 seconds before liftoff. The team is currently reviewing all data and will determine the path forward. A new launch date will be provided when available

The NRO is a joint Department of Defense-Intelligence Community organization responsible for developing, launching and operating America’s intelligence satellites to meet the national security needs of the United States.

United Launch Alliance’s Delta IV rocket has served the nation’s high-priority U.S. Air Force and National Reconnaissance Office space programs with distinction since entering service in 2002.


On November 1, 2018, the USS John P. Murtha recovered the test version of the Orion capsule at sunset in the Pacific Ocean. The Underway Recovery Test-7 (URT-7) is one in a series of tests that the Exploration Ground Systems Recovery Team, along with the U.S. Navy, are conducting to validate procedures and hardware that will be used to recover the Orion spacecraft after it splashes down following deep space exploration missions. Orion will have the capability to sustain the crew during space travel, provide safe re-entry from deep space return velocities, and emergency abort.

The vehicle also launched NASA’s Orion capsule on its first orbital test flight and sent the Parker Solar Probe on its journey to become the fastest robot in history while surfing through the sun’s atmosphere. Having flown 37 missions in a variety of configurations ranging from medium-lift to heavy-lifter, the Delta IV continues the legacy of the Delta rocket family that dates to 1960.

NROL-71 will launch aboard a Delta IV Heavy rocket features three hydrogen-fueled common booster coresand a Delta Cryogenic Second Stage. The payload is protected during atmospheric ascent by a composite payload fairing.
