On board the Chinese station, the astronauts from Shenzhou-14 and 15 met for a few days to complete the handover from one crew to another.
Shenzhou-15 arriving there before the departure of Shenzhou-14 (successfully accomplished on December 4), China has now performs for its station what is called a “warm handover,” comparable to what happens on the ISS, avoiding the orbital complex being uncrewed at any time (which the CSS, however, can do and has already done for previous flights Shenzhou-12 to 13, then from 13 to 14).
Launched at the end of April 2021, the Chinese station is entering an operational phase with its two laboratory modules. China has also officially invited countries which so wish to entrust it with experiments that will be carried out in orbit. Flights with astronauts from friendly nations are also part of the plans in addition to an increasingly bold lunar ambition (robotic and crewed).
