Technicians Lift, Prepare EUS Rocket Hardware for Next Phase of Production at NASA Michoud (Photo Release)

Technicians at NASA’s Michoud Assembly Facility in New Orleans lift a ring for the Exploration Upper Stage (EUS) of the SLS (Space Launch System) rocket to move it to another location in the 43-acre factory for further inspection and production. Flight hardware of the SLS EUS, a more powerful in-space propulsion stage beginning with Artemis IV, is in early production at Michoud.

The rings make up the barrel sections for the flight hardware. The Exploration Upper Stage will be used on the second configuration of the SLS rocket, known as Block 1B, and will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and heavy cargo on a precise trajectory to the Moon.

EUS will replace the interim cryogenic propulsion stage for the Block 1 configuration of SLS. It has larger propellant tanks and four RL10 engines, enabling SLS to launch 40% more cargo to the Moon along with crew.

NASA and Boeing, the SLS lead contractor for the core stage and EUS, are currently manufacturing stages for Artemis II, III, IV and V at the factory. NASA is working to land the first woman and first person of color on the Moon under Artemis.

SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon. SLS is the only rocket that can send Orion, astronauts and supplies to the Moon in a single mission.
