"Ask the sky" to ask the sky successfully, what are the highlights?

At 14:22 on July 24, Wenchang Aerospace launched in China. The blue sea and blue sky, coconut wind. The Long March 5 Yao San Load Rocket is equipped with the China Space Station and asked the Tiangtian Experimental Class to take off smoothly at the Wenchang Aerospace launcher. This allows us to build the Chinese space station further.

After that, I asked the Tiangan experimental cabin to complete the front -direction with the heaven and the core compartment to complete the "one" font. This is the first time that the China Space Station has greeted the spacecraft in a state of people.

Building a key battle in space station is of great significance

2022 is the decisive year of completing the construction of the construction of the Chinese space station. This question of the launching task of the test compartment is a key battle for the construction of the space station, which is of great significance.

Asking the test compartment is the first experimental cabin of my country's space station. The main function is to conduct scientific experiments, which will be the main workplace during the track during the track; the main task is to have the unified management and control capabilities of the space station combination, and it has the core compartment The ability to meet, algorize, and moor out; support astronauts to stay in the orbit, provide dedicated air gates and emergency asylum places to ensure the safety of astronauts; and support the launch of scientific experiments and technical experiments in the sealing cabin.

Perform the zero window launch task for the first time

In this task, the long -five B Rockets implemented a zero window launch. It is the first time that the long -five series of rockets perform the zero window launch task. It is also the first time that the "zero window" launch has been implemented since the construction task of the Wenchang launcher.

Liu Bing, the overall deputy director of the Rockets Dean Five B Rockets, introduced: "Asked the Tiangan Experimental Curring needs to be connected quickly with the space station sky and the core compartment. In position, it takes a huge cost to adjust the track; even leads to the termination of the launch, then you need to wait for the next launch window to re -organize the launch, which seriously affects the task cycle. "

As the new -generation carrier rocket with the largest near -ground rail loading capacity in my country, the long five -B rocket has a 20.5 -meter largest domestic streaming cover, and the near -ground rail carrying capacity reaches 25 tons. Ask the Tianjin experimental cabin is the largest load in my country so far, with a weight of about 23.2 tons. The long five -B rocket is the best choice for launching the experimental compartment.

The fire on time is only the beginning, and the precise track is successful. Liu Bing introduced that the long five -B Rockets also applied the take -off time deviation correction technology, with a maximum correction time of 2.5 minutes. "Popular understanding, the Rockets can be delayed at the latest 2.5 -minute launch. At the time of any time in this period of 0 to 2.5 minutes, the Rockets can automatically modify the flight deviation due to delayed launch during the flight. Send it to the scheduled track. "

After that, I asked the Tianjie Experimental Curring will adopt the self -contribution and docking mode. After completing the expansion of the solar wing and multiple changes in the rail, successfully connected to the front -to -be -line interface of the heaven and core compartment, and the core compartment, Shenzhou 14 manned spacecraft and Shenzhou No. 14 manned spacecraft and the Shenzhou 14th manned spacecraft and the Shenzhou 14th manned spacecraft and Tianzhou -4 freight ships form a combination. The microwave radar developed by the 25th Hospital of China Aerospace Science and Technology completed the power supply self -inspection after the experimental cabin was track, and confirmed that the product's working status was normal. Later, at about 120 kilometers apart from the questioning compartment and the core compartment, it was turned on again, and quickly established a stable communication with the microwave response machine installed in front of the sky and the core compartment to maintain the stable and reliable process of docking.

Ask the sky experimental cabin "larger, stronger, more comprehensive, better, more detailed"

According to experts, I asked the Tianjin experimental compartment consisting of working cabin, air gate and resource cabin, with a total length of 17.9 meters, 4.2 meters in diameter, and 23 tons of launch. This head and weight are similar to a carriage of the Beijing Metro Line 13 train. It is the most important single -cabin active aircraft in the world in the world.

The working cabin of the Tiantian experimental cabin is by far and the world's second largest single -secret sealing body. There are 3 sleep areas and 1 sanitary zone in the cabin. After completing the docking, the China Space Station will be more warm and comfortable, and the number of "beds" will be increased to 6. After the launch of Shenzhou 15 manned spacecraft, the two multiplication groups and six astronauts of Shenzhou 14, Shenzhou 15, and 6 astronauts will be achieved. The space station "full customer" runs.

Qi Tian's experimental cabin is also equipped with a pair of two -free flexible solar windsurfing. After all, the wingspan is more than 55 meters, which is longer than half a football field. This also refreshed the record of my country's spacecraft using the solar windsurfing.

According to experts, after the completion of the space station, a sun and winding in the core compartment will be transferred to the tail of the resource compartment of the test compartment. It will become a veritable "main power station". At that time, the three energy parent lines of the Tiangtian experimental cabin will play a greater role and continuously supply power for the combination.

China Aerospace Officer First Welcome Spacecraft Visit

The launch of the test compartment this time will be the first time that Chinese astronauts have welcomed the spacecraft to visit the spacecraft.

According to experts, in the future, astronauts will also be the norm of China Space Station in the rail. After the China Space Station, the astronauts will be rotated by a group, which means that the astronauts need to welcome the arrival of aerospaces such as Tianzhou freight ships and Shenzhou manned spacecraft. Shenzhou 14th astronauts welcomed the test compartment in the orbit, and will provide experience reference for subsequent tasks. In particular, the scheduled telescope that plans to launch next year also needs to stop at the space station on a regular basis to maintain by the astronauts.

In addition, asking the Tianyan experimental cabin to "part -time" the function of the sky and the core compartment. Not only ensure that astronauts stay in the rail for a long time, but also provide special air gates and emergency asylum places to ensure the safety of astronauts. In order to improve the reliability of the space station and ensure the safety of the life of the astronauts, I asked the Tiangan experimental compartment to have a functional backup. When the core compartment had a functional failure, it could be switched to the test cabin. In addition, the Tiantian experimental cabin also equipped with 3 sleep areas, 1 bathroom and kitchen facilities, which will provide conditions for 6 astronauts in the rail conversion. Qi Tian's experimental cabin also equipped with a new outlet air gates, which is the main outlet of the future astronauts. The new air gates are out of the cabin, which is more spacious, and the spacemen are more convenient to get out of the cabin.

It is reported that I asked the Tiangan experimental compartment mainly for the research science research of space life. In terms of test load functions, I asked the Tianyan experimental cabin to carry 8 experimental cabinets such as life ecology, biotechnology and gravity science. Move a large scientific laboratory to space. The astronauts were working as a "bedroom" when they asked the Tianjin experimental cabin.
