Aerojet Rocketdyne Delivers Orion Auxiliary Engines for Artemis 2
- Engines manufactured by
Aerojet Rocketdynewill support the first crewed mission of the Orion spacecraft
- Eight auxiliary engines that control Orion’s orbital maneuvering will be integrated into the service module
Aerojet Rocketdyneis contracted to supply Orion’s auxiliary engines through Artemis 2
Orion will be capable of taking crews to deep space destinations and returning them safely to Earth. Launched on NASA’s new Space Launch System (SLS) heavy-lift rocket, Orion is designed to carry people farther into space for longer periods of time than ever before, withstanding higher levels of radiation and re-entry speeds than any previous human-rated spacecraft.
“Based on the flight-proven R-4D engine, our auxiliary engines will provide critical maneuverability and propulsive support to Orion throughout its mission,” said
The eight 110-pound-thrust bipropellant engines will be coupled into four pairs on the bottom of the ESM. The ESM, which remains connected to the spacecraft throughout the mission until just prior to Orion's re-entry to Earth’s atmosphere, provides propulsion, power, temperature control, air and water for crew members.
The auxiliary engines for Orion are manufactured, tested and qualified at Aerojet Rocketdyne’s
