Take you to fully understand the work list of astronauts

At 3:13 on July 25th, I asked the Tianjin Experimental Cryle to successfully connect to the front port of Tianhe's core compartment. This is the first time the space station has a space staff to carry out space meetings and docking. In order to meet the arrival of the Tiantian experimental cabin, what jobs did Shenzhou 14th astronauts take the group?

Before the meeting

In early July, the Shenzhou No. 14 Aerospace Commissioner started to prepare for various preparations. The transfer and separation and evacuation of Tianzhou -3 freight ships were among them. After the evacuation of the Tianzhou No. 3 freight ship, the front -oriented interface of Tianhe's core compartment "waited", just to welcome the arrival of the Tianshi experimental cabin.

Sort out the cargo bag

On July 23, the three astronauts of Shenzhou No. 14 took the three astronauts to conduct remote operations and docking training, mainly including operational skills training, normal procedures and failure disposal process review.

Astronauts conduct remote operations and docking in rail training

On July 24, astronauts carried out the installation of the handle of the handle, the installation of the physical limit device, and the adjustment of the angle of the smart display.

During the connection period

After asking the Tianjie Experimental Class to enter the independent meeting docking procedure, the astronauts confirmed that the physical limit device was installed in place and the positioning of the docking work position in the remote operation was located. Turn into the hand -control mode for remote operation and dialogue and evacuation operation.

Astronauts are in the work position in remote operations

During the matching of the meeting, the Shenzhou No. 14 Aerospace Commissioner's multiplier to maintain the two. One person is mainly responsible for the monitoring of the connection parameter information monitoring of the parameter information in the self -control mode and the image interpretation and handle control after the transfer of the remote operation. Hand -control remote operations meet with related instructions.

Ask the Tianjin Experimental Class to take over the preferred self -control mode. The hand -control mode is a backup method used in the condition that the self -control system fails and cannot be ruled out, and the decision -making of the hand -control mode should be dependent on the discharge of the self -control system. Throughout the process, the 200 -meter mooring point is a key decision point.

Ask the sky experimental compartment to reach 200 meters moving point

If the Tiangtian experimental cabin reaches 200 meters of mooring point, the self -control overpass docking system fails and the failure cannot be ruled out after the docking is delayed.

If the heavenly experimental cabin has a self -control system failure during the docking of 200 meters from the relative distance from the sky and the core cabin, the ground decision is transferred to the hand -control mode from the ground decision. After entering the hand -control mode, first of all, the astronaut's hand -control remote operation was evacuated to the 200 -meter moving point, and then decided to arrange the subsequent tasks based on the exclusion of the failure.

After the connection is completed

At 10:03 on July 25th, Shenzhou 14 Aerospace took the group to ask the test compartment door and successfully entered the experimental compartment of Wen Tian. After that, the necessary inspection and status settings were performed to confirm that the environment and equipment in the cabin were in a good state.

Aerospace officer asked Tian Temple Experimental Card

On the whole, the setting status setting requires about 2 weeks. During this period, the spacecraft will be established by the manned environment, including setting up the environmental insurance system, health zone, sleep area, and space kitchen, and at the same time complete the unlocking, functional detection, and equipment installation of scientific experimental cabinets equipped in the experimental compartment. , Materials finishing and other work.

After the formation of two -cabin, the work and life arrangement of the astronauts will also change accordingly. In life, astronauts have more space for activity and more exercise equipment; at work, the task arrangements such as the daily station management of the test compartment and the scientific experiment in the cabin are added.

Bleak

Seeing this, everyone must have a preliminary understanding of the working list of the astronauts to welcome the working cabin. Asked the sky, I have successfully asked the sky, and let us wish the astronauts work smoothly in the "Space House".
