On September 13, the Aerospace Development Committee officially announced the launch schedule for the Ask Heaven and Dream Heaven experimental modules on September 19 and 20.
China's space agency seemed to be influenced by the pace set by New Yuan, focusing more on time efficiency and opting for clustered launches even for important spacecraft like these.
Of course, the main reason was the plentiful supply of usable New Yuan-2 rockets, making it easy to allocate two for the mission.
The Ask Heaven and Dream Heaven experimental modules each weigh about 43 tons, and the mass of the Tiangong Space Station in orbit has been steadily increasing due to frequent resupply launches over the past year.
Once the two modules are launched, the Tiangong Space Station will overtake the Hila Space Station by a single-digit margin, weighing in at 230 tons to become the world's second-largest man-made object in orbit.
