Aerojet Rocketdyne Provides Propulsion for Artemis III Mission

Aerojet Rocketdyne, the American rocket and missile propulsion manufacturer, has announced the completion of four RS-25 engines that will power the core stage of NASA’s Space Launch System (SLS) rocket during the Artemis III mission. The mission is a lunar landing that will return humans to the surface of the moon for the first time in over 50 years. The engines have been upgraded following their service during the shuttle program and will generate around 2 million pounds of combined thrust. Aerojet Rocketdyne has also supplied all other propulsion systems for the Artemis III SLS rocket and a majority of the propulsion systems for the Orion spacecraft. The company’s contributions are designed, built and tested at various sites across the country, including Los Angeles, California; NASA’s Stennis Space Center in Mississippi; West Palm Beach, Florida; Redmond, Washington; Huntsville, Alabama; and Orange, Virginia.
