About LEGO NASA Artemis Space Launch System Rocket

Space enthusiasts and young builders aged 9 and up can explore NASA's next-generation space exploration technology with this detailed Technic rocket model. Developed in collaboration with NASA and ESA, the set recreates the Space Launch System that will launch the Orion spacecraft towards lunar orbit as part of the Artemis programme.

The 632-piece model stands over 70 cm tall when fully assembled, measuring 16 cm long and 8 cm wide. The centrepiece feature is an interactive launch sequence mechanism - builders turn a hand crank to demonstrate the rocket's three-stage separation process, showing how the real spacecraft separates during launch.

Display and Educational Features

The set includes four astronaut nanofigures and an information panel, creating an educational display piece that demonstrates space launch technology. The model serves as both a building challenge and a functional demonstration of rocket staging principles.

The realistic proportions and mechanical action make this an engaging introduction to space engineering concepts, combining Technic building techniques with authentic NASA spacecraft details to create an impressive centrepiece for any space enthusiast's collection.
