Mars Surface Features Astronomy Infographic for Planetary Study

Astronomy infographic titled "Mars Surface Features" using an ORBITAL diagram adapted into a planetary surface anatomy layout for Mars, designed for an astrophysics enthusiast. Central composition: a large detailed globe of Mars with major surface regions and landmark features mapped across the disk, plus 2–3 inset zoom circles for key terrains. Clearly include the label "not to scale" in English for all comparative feature sizes and inset distances. Render scientifically reasonable Mars coloration and morphology: iron-oxide reddish terrain with subtle brown, tan, dark basaltic regions, polar caps in bright white, canyon systems, shield volcanoes, impact basins, dune fields, and cratered highlands. Add 7 labeled callouts in English with canonical scientific names and one accurate fact each: "Olympus Mons — shield volcano, height about 21.9 km above datum"; "Valles Marineris — canyon system about 4,000 km long"; "Hellas Planitia — impact basin about 2,300 km in diameter"; "Gale Crater — impact crater about 154 km wide"; "Planum Boreum — north polar cap with seasonal water ice and carbon dioxide frost"; "Planum Australe — south polar region with layered deposits and seasonal CO2 ice"; "Mars — terrestrial planet, mean diameter 6,779 km". Include additional smaller labels for major regions such as "Tharsis Rise", "Arabia Terra", and "Elysium Planitia" with subtle map annotations but no extra dense paragraphs. Add a small scale-reference strip in English: "Mars mean diameter = 6,779 km", "Earth diameter = 12,742 km", "Olympus Mons height = 21.9 km". Visual style: editorial NASA-poster, aurora green & violet palette used in accents, glows, legends, and inset frames while preserving realistic Mars surface colors; dark background with faint starfield, crisp vector-clean contour lines, restrained technical grid, elegant typography, high contrast, serious scientific editorial mood. Include legend elements for "Volcanic province", "Canyon system", "Impact basin", "Polar ice". Add concise metric labels and scale-aware pointers for each feature. Use editorial astronomy illustration, dark-mode-friendly cosmic palette, vector-clean infographic layout. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no UFO / pseudoscience imagery, no watermarks Scientifically accurate facts, no UFO / pseudoscience imagery, no astrology framing. Sizes and distances are typically not to true scale — label as such.
