Preparing for Artemis I Launch
NASA’s Artemis program will land the first woman and first person of color on the Moon to explore the lunar surface like never before. This bold endeavor will begin with the Artemis I launch - an uncrewed flight test.
Artemis I is the first integrated test of NASA’s Space Launch System (SLS) and Orion spacecraft. SLS and Orion will blast off from Launch Complex 39B at Kennedy Space Center in Florida to send Orion into a lunar distant retrograde orbit – a wide orbit around the Moon that is farther from Earth than any human-rated spacecraft has ever traveled. The uncrewed mission will validate the design and safety of SLS and Orion for human exploration missions to follow.
SLS is the nation’s next-generation heavy-lift rocket that will carry humans farther and faster into deep space than ever before. Aerojet Rocketdyne provides the four powerful RS-25 main engines used to help propel SLS with over 2 million pounds of thrust, as well as the RL10 engine that propels the Interim Cryogenic Propulsion Stage (ICPS), or the second stage, of the SLS. This engine provides the power to accelerate the Orion spacecraft to speeds more than 20,000 mile per hour and set it on a course for the Moon.
Aerojet Rocketdyne’s role on Orion includes the 6,000 lbf main engine on the spacecraft’s service module, eight auxiliary engines used to maintain Orion’s in-space trajectory and position, the jettison motor that separates the Launch Abort System from the spacecraft, 12 Reaction Control System thrusters that control the spacecraft’s reentry into Earth’s atmosphere, one nitrogen tank on Orion service module for cabin pressurization and five composite overwrapped pressure vessels that store high-pressure helium to inflate Orion’s flotation system upon water landing.
