Hard sci-fi realistic interstellar ship in a linear configuration. A single massive fusion engine at the extreme rear, emitting a directed blue plasma plume. The engine is followed by a long structural spine covered in massive radiator panels. In the middle of the spine, a single large rotating gravity ring is attached. The front of the ship contains static scientific bays and a command bridge. Strict asymmetrical linear design: Engine at the back, habitats in the middle, sensors at the front. No thrusters at the front. Utilitarian modular aesthetic, white ceramic tiles, metallic trusses, 8k, photorealistic, cinematic lighting from a distant star, orbiting a habitable planet. Voir plus
