On the week of 13th December 2022 wondering what the crew of the Shenzhou 15 are doing in which finalisation of the completion of the Tiangong – China Space Station the Takionaut Crew start with a productive new week taking the Dream crew working soothingly after entering orbit? In which how is life in orbit, in which they’re the second crew besides comrades Shenzhou 14 crew living in T Shape China Space Station. Having a brief moment of watching the crew.
On a The 27th December 2022 the Shenzhou 15 crew of week events update , come and see How does the Shenzhou 15 Takionaut crew draw blood for testing in a microgravity environment? What is the purpose of blood draw? And with Commander Fei Junlong, watch the longer battery life and stronger suction and the wonderful scenes of Shenzhou 15th team in orbit, let’s get to know it together……
On the 9th November 2022 1455 Hour Hong Kong SAR – Beijing time CNSA –China National Space Administration Tianzhou-4 advance cargo spacecraft successfully evacuated from the space station complex….The latest news from the China Manned Space Office the Tianzhou-4 cargo spacecraft that had completed its scheduled mission successfully evacuated the space station complex and transferred to Independent flight stage.
Tianzhou-4 left the space home port and saw for the first time China, which has completed the construction of the basic “T” shape. space station. Beautiful, majestic and spectacular, this beautiful picture will accompany the Chinese people every step of the way to explore the deep space….
This is the large amount of goods that Tianzhou-4 will bring to the Chinese space station. For Takionauts, these goods are comparable to a real gift package. Tianzhou-4 is loaded with Takionauts. Systems, space station systems and space applications, as well as cargo spacecraft systems totalling more than 200 sets of cargo, including packaged packages and direct-installed cargo, as well as 750 kg of additional propellant for the space station, the reason for the increase in propulsion The reason is that the space station needs to use propellant frequently to adjust its attitude while maintaining its orbital altitude during operation, otherwise it will continue to lose orbital altitude. In addition to the loading of goods, Chinese aerospace engineers have also made a series of unique innovations. By adding labels and colored handles, astronauts can easily find the required packages on orbit. Greatly improve the efficiency of cargo transportation and use.
The Tianzhou-4 spacecraft itself is the second point of interest. It is a cargo spacecraft with the largest active transportation capacity and the most comprehensive on-orbit support capability in China. Therefore, the spacecraft was successfully launched and provided material support for the Shenzhou-14 crew. Space station operation support and scientific experiments, this series of actions can effectively verify China’s technical level in the design and manufacture of cargo spacecraft. The third point to watch is the docking of the Tianzhou 4 spacecraft and the Chinese space station. Although the docking of the spacecraft seems to be very light from the TV broadcast, in fact, every spacecraft flying in space orbits is in the Exceeding the first cosmic speed, which is 7.9 kilometers per second, and its weight is often more than 10 tons or even 10 tons, the energy contained in it is very huge. How to accurately control the two spacecraft to achieve precise alignment and safe connection? It is quite a test of the docking mechanism of the cargo spacecraft. In order to achieve this effect, Chinese designers have successfully used the idea of controllable damping through a large number of technical research and program demonstrations to realize the safe docking of the spacecraft through buffer facilities.
The Tianzhou-4 cargo spacecraft was launched into orbit at the Wenchang launch site in Hainan on May 10, 2022, sending about 6 tons of supplies to the space station. At present, the Tianzhou-4 cargo spacecraft is in good condition, and it will re-enter the atmosphere in a controlled manner.

The combination of the Mengtian experimental module and the Long March 5B Yao-4 carrier rocket is transported to the launch area
Decoding Mengtian The Mengtian The launch of the Mengtian experimental module is imminent. The official platform of China’s manned spaceflight has specially launched a series of popular science articles “Decoding Mengtian” to introduce the Mengtian experimental module to everyone. You are welcome to comment in the WeChat message area and ” Manned Space Small Speaker ” Weibo Leave your questions about the Mengtian experimental cabin in the area , let’s explore Mengtian together! The content of the first issue lets us learn about the exclusive “car” of the Mengtian experimental cabin – the Long March 5B carrier rocket .
On October 25, 2022, the Chang Zheng Long March 5B Yao-4 carrier rocket carrying the Mengtian experimental module of the space station was stably transferred to the launch area. Two years ago, the “Chang 5 B” stunned the sky with its perfect first flight, ushered in a “good start” for the implementation of the “third step” development strategic mission of the manned space project, and opened the prelude to the space station phase of the mission, and then sent ” “Tianhe” and “Ask Tian” successfully entered the orbit. As for how to become the backbone of the space station construction, “Chang Zheng 5 B” has given the best answer…
After ten years of grinding an “arrow”, it took off all over the world
The Long March 5B carrier rocket is a large-scale liquid carrier rocket developed in accordance with the requirements of the space station project and to meet the launch mission of the space station compartment. From project approval to first flight, the Long March 5B carrier rocket has gone through nearly ten years of development.
In November 2011, the Long March 5B carrier rocket was officially approved for project approval to undertake the task of launching the space station section. The review was transferred to the initial sample development stage; in November 2018, the Long March 5B carrier rocket was transferred to the sample development stage; in January 2020, the Long March 5B Yaoyi carrier rocket passed the factory review, and the first flight mission load was new The first-generation manned spacecraft test ship and the flexible inflatable cargo return cabin test cabin; in May 2020, the Long March 5B Yaoyi carrier rocket was ignited at the Wenchang Space Launch Site, carrying the first flight payload and successfully entered the predetermined orbit, the first flight mission It was a complete success, and the first flight mission in the space station phase was successfully achieved.
The first mission of the Long March 5B carrier rocket
It takes ten years to grind an “arrow”, and it is heard all over the world. As a new type of carrier rocket specially developed for the construction of manned space engineering space station, the carrying capacity of “Chang 5 B” is the largest among rockets currently in service in my country, with a carrying capacity of 25 tons in low-Earth orbit. The space station module of more than 20 tons was launched into orbit. The successful maiden flight of the “Chang 5 B” marks that my country’s launch vehicle’s low-Earth orbit carrying capacity ranks among the top in the world, laying a solid foundation for the smooth implementation of the follow-up tasks of my country’s space station project.
A number of “black technologies” to create an exclusive “car” for the cabin
The Long March 5B carrier rocket has carried out a number of technological breakthroughs and innovations, and a number of pioneering “black technologies” have created “exclusive vehicles” for the space station cabin.
01 Oversized fairing, more than big
The Long March 5B launch vehicle has the longest and largest fairing in my country at present, with a length of 20.5 meters, a diameter of 5.2 meters, and a volume of more than 345 cubic meters. Such a spacious space is also tailored for the launch of the space station module. In addition, in order to improve the aerodynamic characteristics, the rocket fairing adopts a streamlined Von Karman curve shape, which can better reduce air resistance and reduce the impact of load; at the same time, a rotary separation scheme is adopted for the separation of the fairing to ensure that the super-large fairing is safe and reliable. separation.
Long March 5B launch vehicle fairing
02 “Zero window” launch, every minute and second is accurate
The space station rendezvous and docking mission put forward the requirement of “zero window” launch for the Long March 5B rocket, and the launch time accuracy error should be controlled within 1 second, which requires the rocket systems to prepare in advance and wait for ignition. As an “ice rocket” using low-temperature propellants such as liquid hydrogen and liquid oxygen, the “zero window” launch of the Long March 5B carrier rocket needs to comprehensively weigh the “advance amount” of launch preparation and the “consumption” of low-temperature propellant “evaporation” “relationship. To this end, the developers have improved the reliability of key systems through reliability analysis and testing, and improved the adaptability of each system to the “zero window” launch through the optimization of the pre-launch process, creating the “zero window” launch of low-temperature launch vehicles in my country. precedent.
03 The large-diameter cabin arrows are separated, and the “softness” is used to overcome the rigidity
The diameter of the connection interface between the space station cabin and the Long March 5B carrier rocket exceeds 4 meters. The separation of the cabin and the arrow needs to consider factors such as reliability and impact environment. Adverse effects such as shock to the environment are minimized. Therefore, the rocket adopts the shock reduction scheme of “double isolation frame + damping box”, and applies “particle damping technology”. “Particle damping technology” is a new type of passive vibration control technology. It forms a coupled, closed nonlinear system through particles and dampers. It rapidly dissipates kinetic energy by means of friction and inelastic collisions to achieve the effect of vibration reduction and noise reduction. , so that the space station cabin can feel the “tenderness” of the rocket during the “getting off” process.
04 Directly into orbit with high thrust, in one step
The Long March 5B carrier rocket adopts a one-stage and a half configuration, consisting of a core-stage + booster + canopy combination, so there is no separate attitude adjustment and terminal speed correction system, but the first-stage rocket is used to directly transfer the payload. into the predetermined orbit. When the first-stage engine is shut down, the thrust of about 140 tons disappears within a few seconds, which is equivalent to a sudden “brake” of a high-speed train, and it needs to stop firmly at the designated position. By adopting the attitude control gain optimization and compound guidance method, the developers improved the rocket attitude control accuracy, reduced the influence of guidance error on the accuracy, and made the rocket in the best “attitude” and the most accurate position when separating. At the same time, two reverse thrust rockets have been added, so that the first-stage arrow body of the rocket can avoid the orbital surface of the space station cabin in time, which improves the safety margin of the separation of the cabin and the arrow.
The Long March 5B carrier rocket is not only safe, reliable and capable, but also can customize different “cabins” for different “passengers”. This customized design allows the rocket to better adapt to the spacecraft, so that the spacecraft can operate in Install more loads in limited space to achieve maximum capacity. The Long March 5B Yao-4 carrier rocket launched this time has been customized according to the shape and weight of the Mengtian experimental cabin. In order to meet the working requirements of the Mengtian capsule and the rocket in the launch area, the opening of the operation port is specially designed on the rocket fairing; in order to meet the needs of wireless communication in the ascending section of the Mengtian experimental module, the rocket fairing is also specially designed. The corresponding wave-transmitting port of the fairing was designed; in terms of orbit, the orbit design and the detailed evaluation of the orbit entry accuracy were also carried out to meet the requirements of the Mengtian experimental cabin.
