NASA Artemis Space Launch System (LEGO 42221)

About this set

This LEGO Technic set 42221 recreates the NASA Artemis Space Launch System with 632 pieces and a difficulty of 3/5. The model uses orange, white, black and grey, and includes the rocket body, two solid boosters, a launch tower and a base, plus NASA and ESA logos. A practical build order is to finish the base and launch tower first, then attach each solid booster to the sides of the rocket body, and finally lower the whole stack onto the tower; doing it this way keeps the core from becoming awkward to handle once the boosters are on. Orange is concentrated on the core stage and boosters, white on the rocket body, while black and grey carry the tower and base, so the colour blocking reads clearly. At 3/5 the build involves familiar Technic pin-and-axle connections without being overly complex, making it a good fit for builders who have handled smaller Technic sets and want a space subject with the NASA and ESA markings. Sort the pins and axles by size before starting, and align both the upper and lower connection points when pressing the boosters into place.
