The NASA Artemis launch system space rocket model (42221) inspires boys, girls, and children aged 9 and up to embark on an exploratory journey. This educational LEGO® Technic set illustrates the rocket launch in 3 stages. Turn the crank and watch how the booster rockets detach from the main rocket and how the main rocket itself detaches at the end. When you continue turning the crank, you will see how the upper stage containing the engine module, the Orion spacecraft, and the escape tower also detach.

The rocket building set was developed in collaboration with NASA and ESA. With this model, children can explore the launch system that sent the Orion spacecraft into lunar orbit. The set includes 4 astronaut nano-figures, fun blue flame pieces, and an information plaque to complement the impressive model.

This LEGO Technic building set is a fun gift for space fans. The LEGO Builder app with clear digital instructions gives children confidence in building. The app allows zooming and rotating the model in a 3D view and tracking progress. The set contains 632 pieces.
