The Shenzhou 15 manned spacecraft is the first manned spacecraft to be greeted after the basic configuration of the space station "T" is assembled. Since then, the Chinese space station has opened a long-term manned residence mode . According to experts, face-to-face on-orbit rotations of astronauts will become the norm.

The Shenzhou 16 spacecraft has completed the final assembly and testing work at the launch site and entered the emergency rescue standby state. The final assembly and testing work of Shenzhou 17 and Shenzhou 18 is also in progress.

The astronaut crews of Shenzhou 14 and Shenzhou 15 successfully conducted a space rendezvous at my country's space station on November 30. The two groups of personnel will be handed over, which also means that the crew of Shenzhou 14 will soon complete 6 Monthly residency tasks.

Since the landing time was a cold winter night, the ground team installed and modified vehicles and equipment, and combined with multiple sub-systems such as the air team to carry out multiple all-element joint exercises. At the beginning of the design of the return capsule, the situation of landing at night was considered. After the spacecraft landed, a radio beacon signal would be sent out, and the flashing light at the "shoulder" position of the return capsule would also light up.

The search and rescue mission encountered two unfavorable factors at the same time, low temperatures in winter and dark night conditions. The team members have made targeted preparations: equipped with strong flashlights, head-mounted lights, compass...etc, and put warm babies on the main unit of the equipment and wrapped them with felt to prevent problems such as fast power consumption in severe cold conditions.

The Jiuquan Satellite Launch Center recently organized several search and rescue drills. In view of unfavorable factors such as low temperature and dark night conditions in winter, the helicopter search and rescue team has broken through the key technology of helicopter landing in the Gobi soft sand area at night through 14 sessions of night flight training and landing training; Get ready for quick maneuvers at night.
