NASA Invites Media to Rollout Event for Artemis III Moon Rocket Stage

NASA will roll the largest section of the agency’s SLS (Space Launch System) rocket, which will launch the second crewed Artemis mission, out of the agency’s Michoud Assembly Facility in New Orleans on Monday, April 20. What’s called the top four-fifths of the SLS core stage – the section containing the liquid hydrogen tank, liquid oxygen tank, intertank, and forward skirt – will be loaded on the agency’s Pegasus barge for delivery to NASA’s Kennedy Space Center in Florida.

Media will have the opportunity to capture images and video, hear remarks from agency and industry leadership, and speak with NASA subject matter experts and Artemis industry partners as crews move the rocket stage to the Pegasus barge.

This event is open to U.S. media, who must apply by Wednesday, April 15. Interested media must contact Jonathan Deal at jonathan.e.deal@nasa.gov and Craig Betbeze at craig.c.betbeze@nasa.gov. Registered media will receive confirmation and additional information about the event by email. The agency’s media credentialing policy is available online.

Once at NASA Kennedy, teams will complete the stage outfitting and vertical integration before handing the hardware over to the agency’s Exploration Ground Systems Program that will handle stacking and launch preparations. The Artemis III SLS engine section and boat-tail, which protects the engines during launch, moved from the Space Systems Processing Facility at NASA Kennedy to the Vehicle Assembly Building in July 2025. The four core stage RS-25 engines are scheduled to ship from NASA’s Stennis Space Center in Bay St. Louis, Mississippi no later than July 2026 for integration into the engine section.

The rocket stage with its four RS-25 engines will provide more than 2 million pounds of thrust to send astronauts aboard the Orion spacecraft for the Artemis III mission. Artemis III currently is scheduled for launch in 2027, following the successful Artemis II test flight mission around the Moon that concluded April 10.

Building, assembling, and transporting the core stage is a collaborative process for NASA, Boeing, the core stage lead contractor, and lead RS-25 engines contractor Aerojet Rocketdyne, an L3Harris Technologies company. The core stage is the backbone of the SLS rocket. All five major structures for the rocket stage are manufactured at NASA Michoud. By optimizing space at NASA Kennedy and NASA Michoud for production, integration, and outfitting, NASA and industry can streamline production for a standardized SLS configuration for NASA’s Artemis program.

The Artemis III mission will launch to Earth’s orbit American astronauts in the Orion spacecraft on top of the SLS rocket to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land astronauts on the Moon in 2028. The SLS rocket is the only rocket capable of sending Orion, astronauts, and supplies to the Moon in a single launch.

Artemis III is the second crewed mission under the agency’s Artemis program, where NASA is sending astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and build on our foundation for the first crewed missions to Mars.
