NASA Artemis II Moon Rocket: ICPS Integration - Stacking | Kennedy Space Center

Teams with NASA’s Exploration Ground Systems Program begin integrating the interim cryogenic propulsion stage to the Space Launch System (SLS) launch vehicle stage adapter on Wednesday, April 30, 2025, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. The four-story propulsion system, built by Boeing and United Launch Alliance (ULA), is powered by an RL10 engine that will enable the Orion spacecraft to build up enough speed for the push toward the Moon during the Artemis II crewed test flight.

The Artemis II test flight will be sending NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as well as Canadian Space Agency (CSA) astronaut Jeremy Hansen, on a ten-day journey around the Moon and back.

Artemis II will launch no earlier than April 2026.
