Tian Gong, or the "Heavenly Palace," is China's space station program aimed at creating a modular space station in low Earth orbit. The project began with the launch of the first module, Tianhe, in April 2021, which serves as the core living and working area for astronauts. The Tian Gong space station is designed to support long-term human habitation and scientific research. It can accommodate three astronauts for extended missions and is expected to host various international experiments, contributing to advancements in space science and technology.
