The Lunar Explorer is a browser‑native selenographic instrument that renders the Moon as a rotating, 3D‑projected sphere with geographically accurate surface features.

Every named and unnamed crater, mare, and mission site is placed at real lunar coordinates and projected through the same rotation matrix, with foreshortening, limb fading, and depth‑sorted shading to preserve correct visual hierarchy.

• Explore: Drag to rotate the Moon and tap features to inspect them.
• Learn: View concise mission cards for historic and modern landing sites.
• Observe: Watch maria, craters, and basins move realistically across the visible disc.
