LEGO Mars Mission Science Kit 45202

Simulated Martian Defense

This rover isn't just for exploration; it's got some serious firepower! Those dark blue and white brick sub-assemblies launched from the side aren't just for show. They're part of a clever mechanism designed to test impact forces against Martian rocks, utilizing solid clutch power to ensure a repeatable action feature.
