Aerojet Rocketdyne Supports United Launch Alliance Launch of Orbiting Carbon Observatory-2 into Orbit for NASA

Written by: developer

SACRAMENTO, Calif. (July 2, 2014) – Aerojet Rocketdyne, a GenCorp (NYSE: GY) company, helped propel the Orbiting Carbon Observatory-2 (OCO-2) into orbit for NASA. The OCO-2 was launched from Vandenberg Air Force Base in California aboard a United Launch Alliance Delta II rocket. Aerojet Rocketdyne propulsion included an RS-27A booster engine, an AJ10-118K upper-stage engine and four MR-103G 0.2 lbf spacecraft thrusters.

“As a propulsion provider on every Delta II launch, Aerojet Rocketdyne has been trusted to support the delivery of historic payloads that have expanded scientific knowledge and enhanced our nation’s space-based capabilities,” said Steve Bouley, vice president of Space Launch Systems at Aerojet Rocketdyne. “We’re honored to continue that legacy with the Orbiting Carbon Observatory.”

OCO-2 will be NASA’s first dedicated Earth remote-sensing satellite to study atmospheric carbon dioxide from space. It is designed to collect high-resolution measurements to map the distribution of carbon dioxide in the Earth’s atmosphere. When combined with data from the ground-based network, the measurements will help scientists better understand the processes that regulate atmospheric carbon dioxide and its impact on Earth’s climate. The OCO-2 mission joins an amazing array of payloads launched by the Delta II with Aerojet Rocketdyne propulsion, including the Phoenix Mars Lander; Mars Polar Lander; Deep Impact; Kepler; NEAR Shoemaker and the Mars Exploration Rovers, Spirit and Opportunity, as well as the Global Positioning System Block IIR fleet.

The RS-27A and AJ10-118K engines have helped place payloads into space aboard the Delta II launch vehicle for the U.S. Air Force, NASA and commercial spacecraft missions. With today’s successful launch, the RS-27A has boosted 238 missions, and the AJ10-118K has placed 170 payloads into orbit. The RS‑27A is a liquid-fuel rocket engine developed by Aerojet Rocketdyne for use on the first stage of the Delta II. It provides 200,000 pounds of thrust at liftoff. The engine is a modified version of its predecessor, the RS-27. The AJ10-118K engine produces approximately 10,000 pounds of vacuum thrust for orbital insertion.
