LEGO Icons NASA Artemis Space Launch System

Hey everyone, it’s Tanner. The LEGO Icons NASA Artemis Space Launch System (set 10341) is the LEGO build that finally gave NASA’s modern lunar program a flagship-tier display piece — and at 1m of vertical height with the SLS rocket plus mobile launcher, it’s the tallest space-themed LEGO set ever shipped.

What Makes This Set Special

The SLS is NASA’s super-heavy launch vehicle for the Artemis program — the rocket designed to return humans to the Moon for the first time since Apollo 17 in 1972. The LEGO interpretation captures every iconic feature:

• SLS core stage in iconic orange-and-white livery
• Twin solid rocket boosters with detailed segmented brick patterns
• Orion spacecraft at the top, removable for separate display
• Launch escape system above the Orion capsule
• Mobile launcher tower with detailed servicing arms and umbilical connectors
• Crawler-transporter base with treads and ground support equipment

The orange-and-white SLS livery is the iconic visual signature. LEGO sourced specific orange brick to match the foam-insulation colour of the actual rocket, and the livery is rendered in actual brick rather than stickers. The orange/white contrast reads cleanly from across a room in a way few LEGO sets achieve.

The Build

3,601 pieces, roughly 14 hours across four sessions. Sequenced launcher base first (with the crawler-transporter and ground support), then the mobile launcher tower, then the SLS core stage, then the boosters, then the Orion spacecraft and launch escape system last.

The mobile launcher tower is the engineering centerpiece. Each of the eight servicing arms is built as a separate sub-assembly with hinge connections to the tower spine, allowing the arms to swing into pre-launch configuration or post-launch retraction. The arm-articulation alone is one of the cleanest LEGO mechanism builds in years.

Display Modes

The set delivers three display configurations:

• Pre-launch: rocket on the launcher, all arms extended, mobile launcher in service position
• Liftoff: arms retracted, rocket displayed mid-clearance from the tower
• Post-separation: Orion spacecraft displayed independently of the booster stack

The booster-separation mode is the standout. You can lift the boosters off the core stage to display the post-separation configuration — useful for staging the iconic ascent sequence. Most reviewers don’t notice the separation feature because the box art doesn’t show it.

What to Watch For

The mobile launcher tower is tall and slightly tip-prone. The tower has a high center of gravity once fully built, and bumping the display can shift the tower toward the edge of the base. Anchor the base to a stable surface if you have curious kids or pets.

The SLS livery panel stickers are the most visible sticker work in the set. Stickers go on slightly curved cylindrical surfaces, and alignment matters. Take your time on the livery phase — a misaligned NASA worm logo is the most-photographed flaw in the set.

Display Notes

Footprint: 38cm × 38cm at the base, with a height of 108cm including the launch escape system. The tallest LEGO space set ever made — taller than the Saturn V (21309) by roughly 10cm.

This set pairs specifically well with the Eiffel Tower (10307) for a “vertical landmark” curated display. Both sets command vertical real estate, and together they create a curated display dichotomy — engineering vs. architecture, modern vs. historical.

Is It Worth $260?

At 3,601 pieces it’s $0.072 per piece — exceptional value for a flagship Icons set, beating most space-themed LEGO and standing alongside the Eiffel Tower’s $0.063/piece. The mobile-launcher engineering and the dual-display modes make this one of the most narratively complete space LEGO sets ever shipped.

For NASA fans: must-buy at MSRP. For Icons collectors expanding their vertical-display shelf, this set is the single best entry point into the space LEGO category — the build is engaging, the display energy is unmatched, and the price is below most flagship Icons. Highly recommended.
