An astronaut writes a letter at a desk in the dark space, highlighting solitude and simplicity.

Minimalist illustration style, clean and simple, long shot. In the distance, an astronaut sits at a small desk, writing a letter. The astronaut’s face is obscured by the helmet, with only the gloved hands visible. The scene is centered in a vast, pitch-black space, with the soft glow from a desk lamp subtly illuminating the astronaut and desk. The surrounding darkness is stark and empty, emphasizing the solitude and simplicity of the moment, creating a gentle contrast between the soft light and the clean, dark background.
