Smithsonian Mars Dig Value Set Journey to the Red Planet—no rocket required! With the Smithsonian Mars Dig Value Set, explorers ages 8 and up gain a tactile introduction to planetary science and geology. The kit includes a sand block containing six pieces of basalt similar to Mars’s surface rocks, along with a build-your-own model of the Perseverance rover (wheels, antenna, robotic arm included). As children excavate, build, and examine their finds, they engage in real-world science: learning how rovers collect samples, how Martian geology compares to Earth’s and how scientists prepare for future planetary missions. The included 23" × 17" STEM poster offers visual content on Martian terrain and exploration context. Once completed, the assembled rover and collected rocks become display pieces—an inspiring reminder of Earth’s place in the solar system and a visible reward for the excavation effort. It makes a meaningful gift for budding astronauts, young geologists and curious minds. ⚠ Warning: Choking Hazard – Small Parts. Not for children under 3 years.
