Space exploration themed icon collection

This is a digital illustration featuring a collection of space-themed icons arranged in a clean grid. The style is semi-realistic with a soft, textured finish, reminiscent of modern graphic design assets. Each element, such as the planet Mars, Saturn, and the rocket, is rendered with a warm, desaturated color palette that feels professional and approachable. The icons include astronomical bodies, spacecraft like the rover and the satellite, and charming character-like elements such as the astronaut and the smiling stars. The composition is balanced and orderly, typical of educational graphics or sticker sheets. The background is a crisp white, providing high contrast for the various planetary and celestial objects. The textures on the surfaces suggest a slight grainy or paper-like quality, adding character to the otherwise smooth geometric shapes.
