From 1902 Méliès Sci-Fi to Modern Digital Art: the Evolution of Moon Illustration
The distinct patterns visible to the naked eye from Earth are not continents; they are vast pools of ancient basaltic lava that filled enormous impact basins billions of years ago. These maria have a much lower reflectivity than the surrounding highlands, which are composed of pale anorthosite rock.
When rendering the maria, resist the impulse to paint uniform, dark splotches. The edges of the maria are irregular, jagged, and feathered by millions of years of micro-meteorite bombardment. Use cross-hatching or stippling to blend the maria into the surrounding highlands gradually. Add delicate impact ray systems, long, pale streamers of pulverized debris ejected during catastrophic collisions. The crater Tycho, located in the southern highlands, features a ray system that extends hundreds of miles across the surface; render these with light, feathered strokes using a hard 3H pencil or a fine-tipped eraser.
Scale is essential. Small, circular craters pepper the entire surface, but their density changes depending on the geological age of the terrain. The highlands are crowded with overlapping crater rings, while the smooth maria house fewer, smaller pits. By capturing this geographic variation, your illustration communicates genuine planetary geology rather than generic noise.
