Design Your Own Space Mission Patch! Young space enthusiasts are invited to imagine and create their own space mission patch, just like real astronauts! Using circular templates, markers, and space-themed stickers, children will dream up their own space missions: Will they fly to Mars? Visit a distant galaxy? Search for alien life? Each child will choose a mission goal, name their spacecraft, and design a patch that tells the story of their adventure. As they draw, children will hear inspiring stories about real-life women astronauts, encouraging early interest in space careers and diverse role models in STEM. Finished patches will be displayed during the event to celebrate their creativity and curiosity. Recommended for children in grades K-5. This special activity is part of Massachusetts STEM Week 2025 and is organized by The Space Consortium, the local space education and outreach nonprofit behind Massachusetts Space Week (April 20-26 2026).
