“Constructed from 632 pieces the new 9+ model offers a very unusual feature set (which makes sense as rockets don’t really have any moving parts to replicate). Hidden within its base, 42221 includes a tightly packed set of gears and a crank handle that allows the NASA Artemis... More to blast-off via the mother of all corkscrews, with the booster rockets separating as it does so.”

Full review at thelegocarblog.com

BrickEconomy Expert Review

“The NASA Artemis Space Launch System Rocket offers a refreshingly different Technic build, centered around a substantial vertical mechanism that simulates the staged launch process through coordinated gearbox, worm gear, and string-driven movement. The structure prioritizes mechanical clarity and educational value, with a tall, accurate overall profile supported by well-integrated support towers and booster separation features. While the internal gearing feels more complex than strictly necessary, the finished model stands out as a purposeful... More display that emphasizes function-driven design over decorative detailing.”

Launch a journey of discovery with this NASA Artemis Space Launch System Rocket (42221) toy for 9+ year old boys and girls. The educational LEGO Technic building set shows the moment a rocket launches, in 3 distinct stages.

Turn the crank to see the solid rocket boosters separate from the core stage, which then also detaches. Continue turning to watch the upper stage with its engine module, Orion spacecraft and launch abort system separate. This space rocket toy for children has been developed in collaboration with NASA and ESA, and lets kids explore the space launch system that will launch the Orion spacecraft into lunar orbit. The space toy includes 4 LEGO astronaut nanofigures, fun blue flame details, plus an information panel to create an eye-catching display.
