A colossal orbital space dock floats above Earth in high orbit, designated as "Orbital Forge." This C1-tier modular station spans over 15 kilometers, anchored at Lagrange Point L1. Massive drydock arms extend outward like giant mechanical spines, capable of servicing and constructing spacecraft up to 10 kilometers in length. Hexagonal docking ports, magnetic mooring clamps, and articulated gantry cranes dominate the structure's frame. Below, solar array fields shimmer, powering fusion-based infrastructure and AI-directed robotics. A rotating gravity ring, 500 meters in diameter, spins slowly at the end of a central truss, housing over 1,000 crew members. Cargo pods, drones, and utility skimmers dart between modular habitat bays, industrial tanks, and scaffolded ship skeletons under construction. Earth hangs immense and blue in the background, while the Sun casts harsh glints on metallic surfaces and glowing thruster ports. Style: realistic sci-fi, cinematic space epic, sharp structural detail, wide angle view.
