A photorealistic, hyper-detailed model of an astronaut in a modern NASA Extravehicular Activity (EVA) suit, similar to the Artemis program design. The suit is primarily white with blue and red accents. The helmet features a high-tech, gold-tinted polycarbonate visor. The life support backpack is detailed with pipes, vents, and a control module. The entire model should have realistic PBR textures, showing subtle fabric weaves and metallic surfaces. Standing in a neutral A-pose.
