Moon Valley in Bold Comic Book Style

On the Moon's desolate, cratered surface, a deep lunar valley unfolds with jagged basalt walls and a regolith floor. Harsh sun creates stark, high-contrast lighting with long shadows. Rendered in classic comic book style: bold black ink outlines, exaggerated foreshortening, and halftone shading. A lone astronaut in a white suit stands at the valley rim, tethered rover in tow, Earth visible as a distant blue marble in the black sky. Add panel-like composition with speech balloons (e.g., 'WOW!' 'LOOK AT THAT') and a caption box describing the scene. Use a limited color palette (monochrome with blue accents) or vivid space-color blocks to emphasize drama. The image should feel dynamic, cinematic, and graphic.
