NASA’s Exploration Ground Systems team has successfully integrated the Lockheed Martin-built Orion spacecraft with the Space Launch System (SLS) rocket, marking a major milestone toward the crewed Artemis II mission to the Moon.
The connection, completed on October 19 inside the Vehicle Assembly Building at Kennedy Space Center, signifies mission readiness as NASA prepares for its first crewed lunar flight in over 50 years. The Orion spacecraft—named Integrity by its astronaut crew—was carefully lifted and secured atop the SLS rocket in High Bay 3, bringing the agency one step closer to returning humans to deep space exploration under the Artemis program.
Designed to carry four astronauts around the Moon and back, Orion sits at the heart of NASA’s Artemis II mission. The spacecraft and SLS rocket combination will provide the power, life support, and safety systems needed for long-duration lunar missions. The integration ensures critical systems between the rocket and spacecraft are fully aligned for upcoming testing ahead of launch early next year.
“This milestone represents the incredible teamwork and precision that define the Artemis program,” said a NASA spokesperson. “With Orion now integrated with SLS, we’re closer than ever to sending astronauts farther into space than any mission in over half a century.”
As final testing and validation continue, NASA and its partners are entering the final phase of pre-launch preparations. The Artemis II mission will pave the way for Artemis III, which aims to land astronauts on the lunar surface later in the decade, forming the foundation for sustainable human exploration of the Moon and beyond.
The successful integration of Orion and SLS marks a pivotal step in NASA’s return to crewed lunar missions. With momentum building and international collaboration strengthening, the Artemis program is set to inspire a new generation of exploration and discovery.
