Inspire young explorers with the LEGO® Technic™ NASA Artemis Space Launch System Rocket (42221), an educational and hands-on model designed for boys and girls aged 9 years and up. Developed in collaboration with NASA and European Space Agency, this impressive build brings the real Artemis launch system to life and shows how the Orion spacecraft will be sent into lunar orbit.
This tall, display-worthy rocket recreates the drama of liftoff through an engaging 3-stage separation sequence. Turn the hand crank to activate each phase of launch: first, the solid rocket boosters detach from the core stage; then the core stage separates; finally, the upper stage with its engine module, Orion spacecraft, and launch abort system splits away. The moving mechanism lets kids clearly see how a real rocket transitions from Earth launch to deep-space flight.
Authentic details make this model both educational and visually striking. Blue flame elements simulate engine thrust, while the included information panel adds learning value and turns the build into a museum-style display. Four astronaut nanofigures complete the scene, encouraging storytelling and imaginative play alongside scientific discovery.
As part of the LEGO® Technic™ range, this set introduces young builders to engineering concepts through realistic movement and mechanical functions. The LEGO® Builder app supports construction with intuitive digital instructions, allowing kids to zoom in, rotate the model in 3D, and track progress step by step for a confident building experience.
Whether used for learning, play, or display, this Artemis Space Launch System model makes an inspiring gift for space fans and future engineers who want to explore how rockets really work.
