A lone astronaut in a dusty orange pressure suit with dark blue-gray harness straps and black boots skis across a vast lunar plain, leaving two long parallel tracks in the gray regolith behind. The astronaut is mid-stride, poles planted, pushing forward in 1/6th gravity, each push sending the body drifting slightly upward before settling back. Fine dust hangs in a low haze along the ski tracks. Behind and above, a crescent Earth sits just over the soft curve of the lunar horizon, blue-white atmospheric glow against total black sky. Raw sunlight, crushed shadows, no fill. 8K photorealistic. No logos on the suit."
