Fictional Civic Space Livestream Host Holding Thank You Sign

9:16 aspect ratio vertical fictional civic education livestream screenshot, photorealistic but clearly fictional. A cheerful middle-aged community science host in a clean white flight-style training suit floats in a stylized zero-gravity museum exhibit set, smiling warmly while holding a brushed metal thank-you sign reading "Thanks to Star Mentor for the big rocket". Behind the host, a large circular window shows a vivid blue Earth-like planet and stars, with an original classroom-style orbital habitat interior full of safe educational instruments, soft green and blue indicator lights, and floating model rockets. The fictional short-video live UI shows viewer count "8.88 million", chat comments "Is this really from space class?" and "That rocket gift effect is amazing", plus a bright animated rocket gift overlay. Deep navy, crisp white, and warm gold palette, high resolution, cinematic lighting, no real politicians, no real agency logos, no real platform marks.
