NASA Mars Rover Perseverance

LEGO® Technic set 42158 recreates NASA's Mars rover Perseverance as a 1,132-piece building model, focused entirely on mechanics rather than minifigures. It reflects the rover's real rocker-bogie suspension, robotic arm and camera mast, giving Technic fans a display piece with genuine engineering behind it. Below you'll find the full parts list with colours, so you know exactly what's inside the box.

Description

A working model of a real mission

NASA's Perseverance rover landed in Jezero Crater in February 2021 to search for signs of ancient microbial life and collect rock samples for a future return to Earth. LEGO® Technic set 42158 translates that real engineering into a 1,132-piece model built around the rover's six-wheel rocker-bogie suspension, letting each wheel move independently over uneven ground just like the original. There are no minifigures in this set — the focus stays entirely on faithfully recreating the mechanics and proportions of an actual space exploration vehicle.

Moving parts that matter

Beyond the suspension, the model includes a poseable robotic arm and a rotating mast with a camera head, echoing the tools the real rover uses to study Martian terrain. Out of 1,132 pieces, 207 are unique elements, mainly in black, white, blue and light bluish grey — a palette that matches the rover's functional, utilitarian look rather than a bright toy colour scheme. Building it means working through separate assemblies for the chassis, wheels, arm and mast, which makes the underlying mechanics easy to follow piece by piece rather than just clipping panels onto a fixed shape.

Who this set suits

This is a set for builders who enjoy engineering over decoration: there's no play scene, no minifigures and no printed backdrop, just a self-contained mechanical model that rewards a slow, attentive build. It fits naturally alongside other Technic vehicles or space-themed sets, and its restrained colour scheme means it won't clash on a shelf full of brighter builds. Because the model stands on its own once finished, it also works well as a display piece for anyone interested in space exploration rather than LEGO® building specifically.

Parts list and reuse

The full parts list below breaks down all 1,132 pieces by colour and quantity, which is useful if you're checking for a missing piece or want to see how many technic pins, axles and connectors the set actually uses. Many of these elements are common Technic parts that turn up across other sets, so building 42158 also adds to a general stock of useful pieces for future projects. If you're comparing sets by scale or complexity, the combination of 1,132 total pieces with only 207 unique parts is a useful signal that this build leans on repeated structural elements rather than many one-off pieces.
