Powerful, imposing robotic astronaut hand giving a thumbs-up. Heavy-duty industrial aesthetic with bulky square plates, reinforced carbon-fiber textures, and robust mechanical joints. Bold flat vector art with thick, clean outlines and high-contrast shadows. Monolithic, grand silhouette rendered in solid colors and minimalist geometric shapes. Isolated on a pure white background, SVG-ready.

The image shows a black and white drawing of an astronaut giving a thumbs up against a white background. The astronaut is wearing a full-body suit with a helmet and a backpack, and has a determined expression on its face.
