Chinese space stations are large structures in orbit where astronauts can live and work. The main station, known as Tiangong, is part of China's efforts to advance its space exploration capabilities. It is designed to support scientific research and international collaboration in space. Tiangong consists of a core module and additional laboratory modules. It can accommodate three astronauts for long missions and is equipped with various facilities for experiments in fields like biology, physics, and materials science. The station is expected to be fully operational by the mid-2020s, contributing to global space research.
