Recently, Shenzhou 13 manned spacecraft successfully launched, and completed the radial rendezvous relationship with the Chinese space station day and core cabin.
3 China Astronauts – Qi Zhi Gang, Wang Yaping and Ye Guangfu entered the core cabin and opened a 6-month space life.
The Chinese Space Station welcomed the second batch of visits to the "home" and opened someone to reside in the era of long-term. In the blink of an eye, the Shenzhou 13 mission has been held ten days.
In China, the trail of "capturing" space station in the night sky is a new fashion of many astronomical enthusiasts.
And above space, China Astronauts will also implement tasks such as charting activities, spatial science experiments during the resident period.
The radial rendezvous docking jumped to "Space Waltz" Shenzhou No. 13 and the rendezvous and docking of the day and core cabin, the first radial rendezvous docking of China’s manned spacecraft implemented in space, that is, through the sky and core cabins Intersessionate and docking. Why do you want to carry out the radial rendezvous? Sun Jun, the approved staff of the Beijing Space Flight Control Center Space Station, said that when the astronaut passenger station is performed, there will be two spacecraft docking space stations, while the radius rendezvous can improve the channel and means of the station space station.
Previously, the Tianzhou No. 2, Shenzhou No.2 and Tianzhou No. 3 spacecraft were both forward or backward. When docking, the core cabin and the spacecraft are "connected to a line". After the Shenzhou 11 is connected, it is vertical with the core cabin.
At present, China Space Station has realized the core cabin, 2 freight spaceships, and one carrier a total of 4 aircraft combination operation. According to experts, the engine, control system and sensor of Shenzhou spacecraft is designed to be designed for all-round and space stations, and only Shenzhou spacecraft can carry out the radiopa. Although the radial docking is only 90 degrees, the difficulty of "space Waltz" is not small.
In the forward, then rendezvous, the spacecraft has a 200-meter holding point, even if the engine does not work, the spacecraft maintains a stable gesture and track longer. However, the radial intersection has no stable mooring point, which requires continuous control of spacecraft attitude and track, and the propellant is consumed, and the fault is difficult. During the radial rendezvous process, the spacecraft should perform a wide range of gesture machines such as flat flight. This puts higher requirements for spacecraft sensitive. As the "eyes" of the spacecraft, the sensitive must have a high ability to identify the target and the ability to interfere with complex illumination.
The Shenzhou-thirteen radial rendezvous and docking the entire process is the command of the guidance navigation and control (GNC) system, which is completed by spacecraft intelligence.
According to experts, in the future space station manned rendezvous mission, the radial rendezvous and the front rendezvous will be used alternately. The first radial rendezvous and successfully implemented, in the absence of the technical research and ground experiment of the Shenzhou spacecraft developed in the Wuzhou Spaceship of China Aerospace Science and Technology Group. In order to meet the different configurations of the spatial station assembly and the state of stay in different parking spaces, the development team has designed new relationship paths and winding models, increasing the flying, fast rendezvous and docking, radial rendezvous.
More than 1 month ago, Shenzhou 12 and the space station assembly completed the flying and radial rendezvous trial, which laid a technical foundation for Shenzhou 13. The mechanical arm mission upgrade "Space Class" continues to open in Shenzhou 12 mission, "all-round" core cabin mechanic arm has become a hot spot in all walks of life.
Through two outgoing activities, Shenzhou 12 mission first inspected the capacity and safety of astronauts and mechanical arms and the reliability and security of the relevant support equipment related to the cabin activities. In Shenzhou 13 mission, the mechanical arm is still one of the "protagonists" of the task. China Manned Space Project News Spokesperson, Lin Xiqiang, deputy director of the China Manned Space Project, said that the main purpose of Shenzhou 13 mission includes the transfer of mechanical arm auxiliary cabins, hand-controlled remote operation and other spatial stations assembly construction key technical test; 2-3 times the cabin activity, install the size of the arm arms combined with the shift and the suspension device, and prepare for the construction task of subsequent space stations.
Zhou Jianping, chief designer of China Manned Space Engineering, said that the task of the future mechanical arm will be more complicated.
For example, after the space station is built, if you need to collect the solar windsurfing of the core cabin, you will need a synergist of astronauts and robotics.
Shenzhou No. 13 is the longest manned flight for China to date, and will first assess and verify that the space station mission will be in the long term. Lin Xiang said that in the rail residence for 6 months, it is the normalization of astronauts, the normalization dwell period during the operation period of the space station.
To this end, Shenzhou No. 13 mission will further verify the health, life and work guarantee technology of the astronauts in the track. Lin Xiang said that the Shenzhou 13 mission will conduct a comprehensive assessment of astronaut health status for different periods and different individuals. According to the results of the assessment, adjustment of the astronauts failure and protective exercise projects, astronaut nutrition meals and psychological support activities.
At the same time, for the female astronauts to participate in flight missions, focusing on living security, health protection, etc., ensuring the long-term flight, healthy life, and efficient work. In the space, scientific experiments are also one of the main missions of the space station. Shenzhou No. 13 mandate will carry out scientific and technical test and application in the field of aerospace, micro-gravity physical field. It is foreseeable that China Space Station is expected to have a large number of scientific research data from different fields, producing high levels of scientific achievements.
In 2013, Shenzhou 10 mission. Astronaut Wang Yaping has conducted a "space teaching", 60 million primary and secondary school students in the country, "Space Class" harvested enthusiastic response.
This time, I follow the Shenzhou 11th to enter the space station, Wang Yaping will continue to start. Lin Xiang said that the space station as a national space laboratory, which contains a unique, extremely rich science education resources. China Space Station is not only a research platform for global scientists to carry out space science, spatial technology, and space applications, but also encourages young people to love aerospace, participate in exploration, and pursue scientific practice platforms.
To this end, this task has planned a more popular science education.
After the end of next year, the construction of the third-class combination of the Space Station is the sixth flight task in the key technical verification phase of the space station. It is also the "battle battle" of the stage.
Subsequent, China’s manned spaceflight project will be fully transferred to the construction phase of the space station. Linxiqiang introduced that the spatial station construction phase planned to implement 6 flight missions – first launched the Tianzhou 4 cargo spacecraft, transporting supplies, preparing for the Shenzhou No. 14 manned flight mission implementation; Shenzhou 14th During the branch, the day laboratory and dream-day laboratory will be launched, docking with the day and core chamber, and performing the intervail. At the end of 2022, China will complete the construction of the three-class combination of the space station, followed by the implementation of the Tianshu five freight replenishment and Shenzhou 15 manned flight missions. The Shenzhou 15th passenger will carry out the rail roller with the Shenzhou-14 passenger. After a comprehensive assessment of the status of the space station, it will be transferred to the spatial station application and development phase. Subsequent, China will also select the machine to launch the tangible space telescope, with the space station commonly independent flight, carry out a patrol observation, and the short-term stop space station for supply and maintenance upgrade.
Zhou Jianping introduced that the resolution of the patrol telescope and the Hubble telescope were quite, but the angle of the field of view of the patrol telescope was more than 300 times more than the Hubble telescope. Many international scientists were very interested.
"We have been promoting this work, will open science facilities and welcome more scientists to cooperate.
"Lin Xiang said that for astronauts in other countries to enter China Space Station, launch international cooperation, and China’s welcome attitude.
I believe that after the China Space Station completed the construction, entered the operation and application development stage, everyone will see the flight tasks of other countries to participate in the flight task of China Space Station. Lin Xiang said that the completion of the China Space Station will provide a better platform for more extensive international cooperation including as astronauts. At present, many countries and regions have put forward the will of this area.
Sino-foreign cooperation in the selection training in astronauts has been carried out.
For example, Chinese astronauts have participated in the training in Russia.
For another example, Shenzhou No. 13 Astronaut Ye Guangfu participated in the cave experiments organized by the European Air Bureau in 2016. European astronauts also participated in the China Organized Maritime Life Training. (Editor: Li Qiangqiang, Zhang Hua Wei) Sharing More people see.
