United Launch Alliance successfully launches NROL-42 mission for the National Reconnaissance Office
A United Launch Alliance (ULA) Atlas V rocket carrying a payload for the National Reconnaissance Office lifted off from Space Launch Complex-3 on Sept. 23, at 10:49:47 p.m. PDT. Designated NROL-42, the mission is in support of national security.
“Congratulations to the entire team for overcoming multiple challenges throughout this launch campaign. From Hurricane Irma schedule impacts to replacing to a first stage battery this week – the team maintained a clear focus on mission success,” said Laura Maginnis, ULA vice president of Government Satellite Launch. “NROL-42 marks the 25th ULA-launched NRO mission, building upon our legacy of partnership with the NRO in providing reliable access to space for our nation’s most critical missions.”
This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 541 configuration vehicle, which includes a 5-meter payload fairing (PLF) and four solid rocket boosters. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C engine.
This is ULA’s sixth launch in 2017 and the 121st successful launch since the company was formed in December 2006.
ULA's next launch is the NROL-52 for the National Reconnaissance Office. The launch is scheduled for Oct. 5 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida.
The EELV program was established by the U.S. 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 legacy launch systems.
With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered more than 120 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.
