Astronaute Surplombant un Désert Rouge

Cinematic ultra-wide shot of [a lone astronaut] standing on a rocky ledge facing away from the camera, looking out across [an immense red desert plain on a Mars-like planet]. The astronaut is positioned in the lower center of the frame, wearing [a realistic white EVA spacesuit with subtle gray panels, life-support backpack, heavy boots, and dark gloves], seen from behind. The landscape is vast and barren, filled with rust-red dust, scattered stones, a rugged cliff edge in the foreground, and hazy mountain ranges along the distant horizon. Lighting: gentle late-afternoon sunlight casting a long shadow forward, soft warm peach and terracotta palette, thin atmospheric haze. Style: photorealistic sci-fi film keyframe, natural cinematic color grading, epic scale, solitary exploratory mood. Constraints: no buildings, no vehicles, no text, no HUD, no other people.
