In half a year of space life, Shenzhou 14 witnessed the completion of the assembly of the Chinese space station from the “one” configuration to the “T” configuration .
The 3 astronauts completed 5 rendezvous and docking, 3 separation and evacuation, 2 module transfers, 3 out-of-cabin missions and 1 Tiangong classroom activity, and carried out a number of space science and technology experiments.

When the mission was coming to an end, Shenzhou 14 was in orbit and welcomed the follow-up crew of Shenzhou 15. After 3 days of work handover, the crew in charge of the space station was successfully transferred from Shenzhou 14 to Shenzhou 15.
This is the first on-orbit crew rotation in China’s manned spaceflight.
While congratulating Chen Dong, Liu Yang, and Cai Xuzhe on their triumphant return, we might as well review in chronological order what work they have completed in the past six months of space travel.

After the rocket entered orbit, it adopted the “rapid autonomous rendezvous and docking” mode. After about 6.5 hours, it successfully docked at the radial docking port of the space station sky and core module node module. Three astronauts successfully entered the Tianhe core module of the space station.

At this time, the space station assembly consists of one cabin + three ships, that is, the Tianhe core cabin and the Tianzhou-3 and Tianzhou-4 cargo spacecraft docked in the forward and backward directions respectively, and the Shenzhou 14 docked in the radial direction manned spacecraft.

The Tianzhou-3 cargo spacecraft docked in the forward direction is separated from the space station assembly, leaving a forward docking port for the docking of the subsequent experimental module.

It is worth mentioning that after Tianzhou-3 separated from the space station, it did not re-enter the atmosphere immediately, but carried out a number of extended technical tests.
One of the more noteworthy items is the technical verification of “co-orbital flight” . The cargo ship and the space station maintain a relatively stable flight in tandem, which will be the orbit of the follow-up CSST sky survey space telescope .
After 10 days of independent flight, Tianzhou-3 was loaded under control.

The first large-scale experimental module of the Chinese space station, the Wentian Experimental Module , was successfully launched into orbit by the Long March 5B Yao-3 carrier rocket.

After the Wentian experimental module was put into orbit, after about 13 hours of rendezvous flight, it successfully docked at the forward docking port of the space station’s sky and core module node module.

Subsequently, the astronauts of Shenzhou 14 successfully opened and entered the Wentian Experimental Module, which is the second on-orbit working module and living module of the Chinese space station.

Astronauts of Shenzhou 14 carried out the first out-of-vehicle activity in the mission. Chen Dong and Liu Yang performed the extravehicular mission, and Cai Xuzhe stayed in the cabin to cooperate with the operation command.
After Wang Yaping, Liu Yang became the second female astronaut in China to perform extravehicular activities .
This is the first use of the weather lock cabin . In the previous missions, the astronauts entered and exited the cabin through the core cabin node cabin. Q The weather lock cabin is the main airlock for astronauts in and out of the Chinese space station.

Astronauts of Shenzhou 14 carried out the second extravehicular activity. Chen Dong and Cai Xuzhe performed extravehicular missions, and Liu Yang stayed in the cabin to cooperate with the operation command.
This trip was only 16 days away from the last trip. In addition to normal extravehicular operations, it also verified the support capability of the space station for short-term emergency exits .

The Wentian experimental cabin uses plane transposition to complete transposition. This is the first time that China has completed the transposition operation of a large-scale module in orbit, and it is also the first time in the world to complete the transposition of a spacecraft with a planar transposition scheme.
The successful transposition of the Wentian experimental module means that the Wentian module is docked at the permanent berth, which also leaves a forward docking port for the Mengtian experimental module that will be launched into orbit later.

The crew of Shenzhou 14 carried out the third space teaching activity on the space station. This is the first time that Chinese astronauts give lectures in the Wentian experimental cabin.
In the classroom, the three astronauts introduced the living and working facilities of the Wentian experimental cabin.

Like the Wentian experimental module, after about 13 hours of rendezvous flight, the Mengtian module successfully docked backwards at the forward docking port of the space station and the core module.

Different from the Wentian experimental cabin, three days after the completion of the Mengtian docking, the Mengtian experimental cabin successfully completed the transposition, and docked again with the side permanent berthing port of the Tianhe core cabin.

After the transposition was completed, the astronauts of Shenzhou 14 successfully opened and entered the Mengtian experimental module, which is the third on-orbit working module and living module of the Chinese space station, and the last large-scale module in the “T” configuration of the three modules. compartment.

The Tianzhou-4 cargo spacecraft docked at the back of the space station completed all the scheduled tasks, evacuated the space station assembly, and entered the state of independent flight.
During the separation and evacuation, the docking monitoring camera of the Tianzhou-4 cargo ship also clearly recorded the complete picture of the complete configuration of the “T” character of the Chinese space station.

A week later, the Tianzhou-4 cargo spacecraft re-entered the atmosphere under control. Most of the cabin structure was burned in the atmosphere during the re-entry process, and a small amount of debris eventually fell into the predetermined safe sea area of the South Pacific.

It is very worth mentioning that after the Tianzhou-5 cargo ship entered orbit, it used a faster rendezvous and docking mode. From orbit entry to rendezvous and docking completion, it took about 2 hours in total.
This set a speed record for a visiting spacecraft rendezvous and docking on the space station .

The Shenzhou 15 crew opened the front hatch of the orbital module of the Shenzhou spacecraft, and the crew of the Shenzhou 14 astronauts who were still staying at the Tiangong space station opened the hatch of the Tianhe core cabin.
This is the first in-orbit rotation of Chinese astronauts, and the Chinese space station has entered a long-term manned resident mode.

The crew of Shenzhou 14 successfully completed all the scheduled tasks for 6 months, and the spacecraft separated from the space station at noon. After flying about 5 laps independently, using the fast return mode, it successfully returned to the Dongfeng landing site where it was scheduled to land.
The Shenzhou 14 manned spaceflight mission was a complete success.
During the 6-month flight of Shenzhou 14, it has experienced the most space station configuration changes in a single mission of China’s manned spaceflight so far, ushered in the most spacecraft to join, and also witnessed the completion of the assembly and construction of China’s space station.
Subsequently, after the on-orbit evaluation of the three-cabin combination, the space station will enter the formal operation stage for more than ten years. The focus of work will also gradually shift from engineering construction to space science applications. The site is used to build a national space science laboratory.
“China’s space station is always worth looking forward to!” | CCTV News
While thanking the flight crew of Shenzhou 14, all the ground participants in the research and test, and the aerospace staff for their six-month hard work, we also look forward to more exciting follow-up events on the Chinese space station.
