NASA’s Space Launch System is the most powerful rocket ever built, and now someone’s gone and replicated it in LEGO at 1/110 scale — complete with three separate Artemis mission configurations. That’s not a typo. One build, three missions, 2,787 bricks.
Builder whatsuptoday42 has engineered both the Block 1 and Block 1B crew versions of the SLS, meaning you can display this beast in its Artemis I (2022), Artemis II (2026), or Artemis III (2027) configuration. The orange core stage is instantly recognizable, flanked by those chunky white solid rocket boosters sporting accurate NASA worm logos, American flags, and black checkered roll patterns. The color blocking alone — that signature orange against white with yellow separation bands — is spot on.
What really sets this apart is the engineering under the shell. The interstage section uses a clever internal Technic framework with bracket connections and clip mechanisms that allow the Orion capsule to separate cleanly from the upper stage. It’s the kind of detail you only see when a builder has spent serious time studying reference photos. The four RS-25 engine bells at the base are properly clustered, and the launch abort system tower crowning the Orion capsule gives the whole thing that distinctive silhouette.
The build comes with a massive 650-page building guide, nine printable decal sheets, and BrickLink-compatible parts lists — so this isn’t just a showpiece render, it’s a fully documented project you can actually source and build. With 335 unique elements across those 2,787 bricks, the parts diversity alone tells you this is a serious piece of LEGO engineering.
At 681 photos on Flickr, whatsuptoday42 is no newcomer to the MOC scene. This SLS build is a standout even in a deep portfolio — the kind of project that makes you want to clear a shelf and start ordering parts.
