{"id":98679,"title":"GRU Space - The Moon Factory","tagline":"GRU's Moon Factory will build the world's first bricks on the Moon \u0026 permanent lunar infrastructure.","body":"In just 6 weeks, GRU Space built the world’s first [Moon Factory](https://youtu.be/k9X7TuAxNrw) for under $5,000. GRU’s patent-pending prototype autonomously: \n\n• mines lunar soil (regolith)\u2028 \n\n• refines it using a geopolymer process\u2028 \n\n• turns it into structural bricks to build lunar infrastructure GRU has also built a patent-pending modular inflatable habitat designed to withstand the temperature and pressure extremes on the Moon. \n\nCombining with the Moon Factory, it forms the basis of the first lunar hotel, Moon base, and ultimately, permanent lunar infrastructure. \n\nBefore GRU, lunar habitats can only be built on Earth. At hundreds of thousands of dollars per kilogram, that makes large-scale lunar bases nearly impossible. \n\nHumanity has not built a product on the Moon yet. At GRU, we are changing that. \n\nAs early as next year, GRU will land a small-scale version of their factory \u0026 inflatable on the Moon. \n\nHumanity cannot become interplanetary until we solve off-world surface habitation. Once solved, it will become the Promethean moment that will enable billions of human lives to be born on the Moon and Mars.","slug":"Pfb-gru-space-the-moon-factory","created_at":"2026-03-10T22:44:10.081Z","updated_at":"2026-09-19T09:06:34.037Z","total_vote_count":20,"url":"https://www.ycombinator.com/launches/Pfb-gru-space-the-moon-factory","share_image_url":"//bookface-static.ycombinator.com/assets/ycdc/yc-og-image-c440a0ad1dacfb86eeeb343717479cc54d256614449b4ef719977a0a451f8bc8.png","company":{"id":30635,"name":"Galactic Resource Utilization Space, Inc.
