Description

A rocket built for two-stage play

The rocket separates cleanly from its launch tower, letting you replay the moment of lift-off rather than leaving the model fixed in one pose. Larger structural pieces give the build its height and stability, while smaller detail parts around the engines and cockpit keep it interesting to look at from close up. Because the tower and rocket work as independent sections, you end up with two separate play areas instead of one static scene. The five minifigures take on different jobs across the set, from piloting the rocket to working on the ground at the base.

Inside the Mars station

Alongside the rocket, a multi-room Mars station covers living, lab and control areas within one connected structure. Sections of the building open up, so play doesn't stop once the model is finished — there's access to interior fittings, work surfaces and small equipment pieces throughout. That openness also makes the station easier to rearrange or extend later with parts from other sets, rather than treating it as a fixed display piece. Combined with the rocket, the station turns a single set into a full Mars mission split across two connected but independent locations.

A white, grey and purple colour scheme

White and light bluish grey form the main surfaces of both the rocket and the station, giving the model a clean, technical look typical of space builds. Dark purple is used as an accent throughout, on struts, connectors and equipment, which keeps the model from feeling one-note. Black appears mainly around windows, engines and other technical details, adding contrast where it's needed. If you want to see exactly how these four colours are distributed across the 331 unique parts, the full list on this page breaks it down piece by piece.

Who this set suits

At 981 pieces, this is a set for builders who already have some experience and want a project with real scope, rather than a quick afternoon build. The split between rocket and station means there's plenty to do with it once assembly is finished, since both sections can be played with on their own. For anyone building up a parts collection, it's also worth noting which elements — particularly the purple and grey technic-style pieces — could be reused in other space-themed builds. The parts list on this page makes it easy to check colours and shapes before you start.
