Rank 49 documents Tiangong — China's modular space station programme that assembled Tianhe, Wentian, and Mengtian modules into a fully operational T-shaped orbital laboratory by late 2022. Launched aboard Long March 5B and Long March 2F vehicles from Wenchang and Jiuquan, the station supports continuous Shenzhou crew rotations — completing China's independent human spaceflight infrastructure decades after Shenzhou 5 made Yang Liwei the nation's first astronaut. Tiangong provides microgravity research capacity, Earth observation platforms, and technology demonstration berths that place China among the three nations operating permanent crewed orbital facilities alongside the ISS legacy and Russia's evolving station plans. Wallimilist renders the T-module cluster hero with solar array paddles, red orbital-plan arc, Long March 5B Wenchang pad inset, cream archive with TIANGONG slab title, TIANGONG FULLY OPERATIONAL kicker, and CHINA'S PERMANENT LEO LABORATORY footer exactly as the master PNG dictates — CNSA and Tiangong emblems, specimen data bands, and curator copy on Chinese station heritage.
