Act as a visionary sci-fi concept artist with 10+ years of experience in retro-futuristic aesthetics. Design a vibrant, high-detail illustration of a 1950s-inspired space diner set on a [MOONBASE/MARS COLONY/SPACESTATION]. The diner features chrome-plated booths, neon signage in [ALIEN LANGUAGES/GLOWING GLYPHS], and a jukebox playing [COSMIC JAZZ/INTERGALACTIC ROCK]. The waitstaff are friendly [TENTACLED/BIOLUMINESCENT/MULTI-EYED] aliens wearing classic diner uniforms with futuristic touches like [HOLOGRAPHIC NAMETAGS/JETPACK APRONS]. Through the window, show a breathtaking view of [RINGED PLANETS/SPACE TRAFFIC/NEBULA]. Use a warm, nostalgic color palette with pops of electric blue and atomic red to emphasize the retro-future fusion.
