China's Starry Sky | 28 manned spaceflight projects delivered in 6 months, China's impressive mid year "report card" Shenzhou | Space Station | Starry Sky | 28 manned spaceflight projects delivered in 6 months
CCTV News: The pure white cabin walls of the space station, bright solar wings, and clear blue Earth are on this side of the Chinese space station. The crew of Shenzhou 16 saw through the porthole the radiance of the stars, sun, and moon shining on the space station, reflecting a bright and flowing light. At this moment, the "Heavenly Palace" belonging to China is slowly flying around the ground. Above our heads are the countless stars we chase, before our eyes are the magnificent mountains and rivers we love, truly handsome beyond the sky!
Yesterday, the China Manned Space Engineering Office released the 2023 China Manned Space Mid Year Achievement Report. In this "transcript", a total of 28 items were recorded. From January 21, the second "Tiangong Painting Exhibition" was officially held in the Chinese space station, when the Shenzhou 15 crew sent a special "New Year gift" to the national youth, it has been recorded that recently, with the cooperation of heaven and earth, the air bottle of the space station electric propulsion system completed the installation task in orbit, involving the three astronaut crew of Shenzhou XIV, Shenzhou 15 and Shenzhou 16. Among them, it also includes multiple scientific experiments and experiments completed on the space station. It can be said that this heavy "transcript" detailed the solid progress of China's manned spaceflight in the past six months.
In this transcript, there is an exclusive release that has received much attention, which is the recently completed installation of the space station's electric propulsion cylinder. According to the China Manned Space Engineering Office, with the cooperation of heaven and earth, the atmospheric cylinder of the space station's electric propulsion system has completed the in orbit installation task, and for the first time, the "air exchange" method has been used to supplement the electric propellant, which plays an important role in maintaining the long-term orbit and safe and stable flight of the space station.
Over the past six months, astronauts have achieved fruitful scientific experiments in orbit
In the past six months, astronauts have conducted multiple scientific experiments and experiments in orbit, with multiple projects being the first.
In the 2023 China Manned Space Year Transcript, multiple scientific experiments and experiments completed by the crew of Shenzhou-15 astronauts are included. In March of this year, with the collaboration of ground researchers and astronauts, the crew of Shenzhou-15 completed the first ignition test of the combustion science cabinet experimental system. Methane was used as fuel in the ignition experiment, and the entire ignition and combustion process was clearly captured by a high-speed camera, laying a solid foundation for the smooth implementation of subsequent projects.
The space station two-photon microscope project has also conducted in orbit experiments and achieved success, which is also the first time that three-dimensional images of astronaut skin epidermis and superficial dermis have been obtained during space flight.
In addition, the space efficient free piston Stirling thermoelectric conversion test device has successfully completed in orbit tests, and comprehensive technical indicators such as thermoelectric conversion efficiency have reached the international advanced level.
In May of this year, after more than 5 months of in orbit observation experiments, three astronauts from Shen-15 successfully observed the process of generating conductive ring debris and cluster phenomena in orbit for the first time. At the same time, the space station aerospace technology testing field has also completed China's first liquid metal thermal management in orbit test, achieving a series of key technological achievements.
From June 9th to 10th, the crew of Shenzhou-16, who had just moved into the space station, also completed the removal of the space radiation biology exposure experimental device for the Mengtian experimental module. This is also the first time China has conducted an extravehicular radiation biology exposure experiment.
The work of the Full Moon God Sixteen Riders in orbit is being carried out in an orderly manner
It has been a month since the crew of Shenzhou 16 entered the Chinese space station on May 30th. During this period, astronauts Jing Haipeng, Zhu Yangzhu, and Gui Haichao worked together to carry out a large amount of work with high frequency and efficiency.
Recently, three astronauts conducted cytological research sample recovery work in the Tianhe core module, including the recovery of sampling bags, cell culture plates, sample transfer, and other steps. In addition, astronauts also conducted in orbit testing of emergency breathing devices, which are specifically designed for astronauts to cope with special situations under pressure emergency conditions. Since entering the space station, astronauts have successively carried out tasks such as payload removal, equipment testing, experimental project implementation, and cabin section inspection and maintenance.
As the first manned flight mission of the space station application and development project, astronauts Jing Haipeng, Zhu Yangzhu, and Gui Haichao will stay at the space station for about 5 months to carry out platform care work such as extravehicular camera lifting; The installation of external application facilities such as universal testing devices for components and components will be completed; Carry out large-scale in orbit experiments and experiments in multiple fields as planned; It is expected to produce high-level scientific achievements in the study of novel quantum phenomena, high-precision spatial time-frequency systems, verification of general relativity, and research on the origin of life; We will also carry out the "Tiangong Classroom" space teaching activity, allowing manned spaceflight to once again enter the classrooms of primary and secondary school students.
At present, the space station assembly is a brand new configuration of "three cabins and three ships"
At present, the space station assembly consists of the Tianhe core module, Wentian experimental module, Mengtian experimental module, Shenzhou 16 manned spacecraft, Tianzhou 5 cargo spacecraft, and Tianzhou 6 cargo spacecraft, forming a new configuration of "three modules and three ships".
The image we are seeing now is the same frame image of the core module and the robotic arm captured by the Tianhe panoramic camera. This is a footage captured by an extravehicular camera of the Shenzhou-16 manned spacecraft docked at the radial docking port of the core module node module. Through the panoramic camera outside the Mengtian module, we saw the hatch of the cargo airlock of the Mengtian module. From T-shaped configuration to "three cabins and three ships", what changes will China's space stations undergo in the future? Listen to Yang Hong, academician of the CAE Member and chief designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group.
Yang Hong, the chief designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group, an academician of the CAE Member, said that the configuration you saw was a basic type when two groups were rotating a few days ago. In fact, the real configuration you didn't see was 53 types. Taking all factors into consideration, it can be further expanded in the future. That is to say, with the current configuration of the space station, while flying in the sky, there can be several companion modules behind the space station, which can perform scientific experimental tasks independently on weekdays. When it needs fuel supply and maintenance, it can autonomously dock to the space station. There can be more than N spacecraft like this, all of which can fly with the space station. This forms a model of a space home port centered around the space station, which is unique to China's space station.
Before the arrival of Shenzhou 17, Tianzhou 5 will be evacuated again
In a few months, the configuration of the Chinese space station's "three cabins and three ships" will also undergo further changes. On June 6th of this year, the Tianzhou-5 cargo spacecraft, which had been evacuated earlier, completed its rendezvous and docking with the space station complex on the same day after flying independently in orbit for 33 days. It is understood that the Tianzhou-5 cargo spacecraft has once again arrived at the Chinese space station to provide more available space for the crew of Shenzhou-16 astronauts. In the coming months, the crew of Shenzhou-16 astronauts will use the remaining space of Tianzhou-5 to store waste. Before the arrival of Shenzhou-17 manned spacecraft, Tianzhou-5 cargo spacecraft will be evacuated from the space station again and re-entered the atmosphere to complete ablation and destruction.
At present, the space station assembly is in good condition, and various work will be carried out as planned in the future.
