Space Station Designer

Space Station Designer is a construction and management game where you become the CEO of a private aerospace company, in charge of creating and operating a thriving network of orbital outposts. Begin with a single core module in Low Earth orbit and gradually extend your operations into higher Earth and Lunar orbits. Design self-sustaining stations, manage astronauts and logistics, unlock advanced technologies, and help shape humanity’s space economy. Your ultimate ambition? Construct and operate a Lunar Space Elevator Megaproject. Space Station Designer features three game modes: Campaign Mode: Learn the systems through guided objectives, while developing your company through contracts, expansion, and long-term planning. Sandbox Mode: Skip the onboarding phase and jump directly into an open-ended management experience with contracts available from the start. Free Builder Mode: Experiment freely with every unlocked module and create your dream station designs without budgets or operational limits. Every station is fully modular and assembled piece by piece. Build using 150 unique modules Reconfigure and optimize stations as your needs evolve Balance life support, power generation, logistics, crew wellbeing, and profitability Create specialized orbital infrastructure across multiple locations From compact orbital outposts to sprawling industrial hubs, every design decision influences operational efficiency and long-term growth. Success in orbit requires more than just engineering. As the CEO of a private space company, you'll perform a wide range of activities including recruiting and managing astronauts, building and installing modules, providing commercial services, manufacturing goods, commercializing industrial R&D technologies, accommodating space tourists, leasing modules, and a lot more. Whether you specialize in manufacturing, commercial services, or space tourism – or pursue a diversified strategy – your company’s direction is entirely yours to define. Developed by the creators of Buzz Aldrin’s Space Program Manager and inspired by NASA concepts and decades of space exploration literature, Space Station Designer presents a grounded and optimistic vision of humanity’s future in space. If you enjoy city builders, management games, and space exploration, Space Station Designer offers a deep and interconnected simulation of life, logistics, and industry in orbit. Design, build, and manage a network of orbital stations across Earth orbit and beyond. Fully modular stations using 150 unique modules Choose your playstyle: Campaign, Sandbox, or Free Builder mode. Recruit and manage astronauts to keep stations operational and productive Coordinate cargo and crew transportation across your orbital network Research and unlock advanced technologies to expand operational capabilities Manufacture commercial goods and establish profitable industrial operations Provide commercial services, lease infrastructure, and support space tourism Adapt station layouts over time by redesigning and optimizing orbital networks Work toward the ultimate megaproject: a Lunar Space Elevator Modding support included, with tools and documentation for creating custom modules, spacecraft, and astronauts
