ULA Atlas V rocket successfully launches fourth NRO payload in five months

A United Launch Alliance Atlas V rocket carrying a payload for the National Reconnaissance Office lifted off from Space Launch Complex-3 at Vandenberg Air Force Base, Calif., at 2:39 p.m., PDT, Sept. 13.

Designated NROL-36, the mission is in support of national defense.

“Today’s successful launch of the NROL-36 mission occurred on the same day as the national memorial service honoring American hero Neil Armstrong. The scientists and engineers developing and operating these remarkable current-day launch and spacecraft systems reflect Neil’s incredible legacy to mankind,” said Jim Sponnick, ULA vice president, Mission Operations. “Today’s launch marks the fourth and final EELV mission for the NRO’s Road to Launch 2012 accomplished in the last five months. This launch tempo is a tribute to all of the mission partners’ dedication and continued focus on mission success – one launch at a time.”

ULA launched NROL-25 April 3 from Space Launch Complex 6 at Vandenberg Air Force Base in California, as well as NROL-38 June 20 from Space Launch Complex 41 and NROL-15 June 29 from Space Launch Complex 37 both located at Cape Canaveral Air Force Station in Florida.

This mission was launched aboard an Atlas V EELV 401 configuration vehicle, which includes a 4-meter diameter payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by a single Pratt & Whitney Rocketdyne RL10A-4 engine.

In addition to the NROL-36 payload, 11 CubeSats took advantage of available volume and structural capacity of the Atlas V launch vehicle for a ride share. The NRO and ULA partnered to develop an Aft Bulkhead Carrier (ABC) on the Centaur second stage, which is a platform for accommodating auxiliary payloads aboard Atlas V missions. Affixed to the ABC was an auxiliary payload called Operationally Unique Technologies Satellite, or OUTSat, carrying the 11 CubeSats in various configurations.

The CubeSats are sponsored by the NRO Mission Support Directorate and NASA’s Launch Support Program, and were developed by the Space and Missile Defense Command, The Aerospace Corporation, University of Southern California, University of Colorado, California Polytechnic State University, Morehead State University, University of California Berkeley and the Lawrence Livermore National Lab.

“These auxiliary payloads are the first of their kind for an Atlas V mission,” said Sponnick. “We are pleased we could support the NRO, NASA, and all of the associated institutions to deliver these important CubeSats which will study space weather and communications, debris mitigation, maritime shipping container tracking as well as space flight safety and orbit refinement.”

Developed by the United States Air Force to provide assured access to space for Department of Defense and other government payloads, the commercially developed EELV Program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.

ULA’s next launch is the Delta IV GPSIIF-3 mission for the Air Force scheduled October 4 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Fla.

ULA program management, engineering, test, and mission support functions are headquartered in Denver, Colo. Manufacturing, assembly and integration operations are located at Decatur, Ala., and Harlingen, Texas. Launch operations are located at Cape Canaveral AFS, Fla., and Vandenberg AFB, Calif.
