At 1750 Hours Hong Kong Beijing Time on a very clear 29th March Tuesday 2022 2022, China- People’s Republic of China- CNSA –China National Space Administration Successfully launched the New Next Generation Long March 6 Chang Zheng 6 carrier rocket at the Taiyuan Satellite Launch Center Shanxi Province …… modified carrier rocket at the Taiyuan Satellite Launch Center, carrying the Pujiang 2 and The Tiankun-2 satellite successfully entered the scheduled orbit, and the launch mission was a complete success.
The launch vehicle is a new generation of non-toxic and non-polluting launch vehicle in China – People’s Republic of China. It is the first solid bundled launch vehicle in my country and is used to launch satellites in sun-synchronous orbit. The Pujiang-2 satellite is mainly used for scientific experimental research, land and resources census and other tasks, and the Tiankun-2 satellite is mainly used for the experimental verification of space environment detection technology. This mission is the 412th flight of the Long March series of launch vehicles.
The Chang Zheng6A Long March 6A modified carrier rocket was developed by the Eighth Academy of China Aviation and is the first solid-liquid bundled carrier rocket in China – People’s Republic of China. This mission is the 412th launch of China – People’s Republic of China Chang Zheng- Long March series of launch vehicles.
Hong Gang, the commander-in-chief of the Changliu, said in an interview that through the adjustment of the boosters in the future, the Chang Zheng6A -Long March 6A reform can form a single-core stage, bundle 2 solid boosters, bundle 4 solid boosters, and bundle a universal core stage. and other configurations to form a series of launch vehicles with a wide range of carrying capabilities, reasonable gradients and high cost performance, to meet the diverse and intensive launch requirements of future satellites.
The Chang Zheng6A -Long March 6A modified carrier rocket adopts a two-stage and a half configuration. The core first-stage power system has a diameter of 3.35 meters and is composed of two 120-ton thrust liquid oxygen kerosene engines in parallel. Pressure medium; the core secondary power system has a diameter of 3.35 meters and is equipped with a liquid oxygen kerosene engine with a thrust of 18 tons. The single flight working time of the engine exceeds 500 seconds; the auxiliary power YF-86A auxiliary power system consists of 18 thrust Composed of 200N and 40N attitude control engines, it provides rolling torque for the second stage of the rocket during flight, and provides pitch, yaw and rolling impulses before the satellite is separated, ensuring that the satellite enters orbit with higher precision.

Referencing to Sixth Academy of Aerospace Science and Technology…..
The “mix and match” of solid power and liquid power is the special feature of this type of rocket. The 4 boosters of the rocket use the two-stage 120-ton thrust solid engine developed by the Fourth Academy of China Aviation, and the core stage adopts the liquid oxygen kerosene engine developed by the Sixth Academy of China Airlines, which gives full play to the high performance, long working time and solid engine of the liquid engine. The advantages of large thrust and simple use and maintenance. The successful first flight of the rocket marks that my country has made breakthroughs in key technologies such as the binding and separation technology of solid boosters, the technology of large concentrated force diffusion at the binding point, and the combined rocking control of solid-liquid binding.
With a brand new “smart launch site complexes” has been put into use, and the new station has been adapted and transformed to be able to launch Seven types of Chang Zheng Long march carrier rocket of launch vehicles During the first flight mission of Chang Zheng 6A Long March 6A, China – People’s Republic of China built the first satellite launch center in Taiyuan. The “smart launch site” was also put into use for the first time, realizing remote control and unattended operation from Carrier Rocket filling to launching.
About four hours before launch, ground personnel were evacuated from under the tower. In the remote control room about two kilometers away from the tower, operators in positions such as air conditioners, platforms, and pendulums keep their eyes on the screen and closely monitor the status of the rocket. Xue Weijun, commander of the intelligent launch site system of Taiyuan Satellite Launch: Before the intelligent launch site was put into use, most of the ground equipment operations were completed by the front-end staff, and the evacuation could only be carried out 15 minutes before the rocket launch. Unattended mode only need to remotely control and monitor in front of the computer terminal, to ensure the normal operation of each work.
The construction of the new launch tower will be completed in 2021, and this is the first time it has been put into use. Under the automatic operation of the system, a series of actions such as liquid oxygen filling, connector falling off, and turning platform opening of the Chang Zheng Long March Carrier rocket were successfully completed, and the rocket entered the launch state. .
Zhang Xin, Commander of Taiyuan Satellite Launch Center No. 1: The measurement and launch process management and control platform is the core of our smart launch site. The status information of the facilities and equipment of the launch site is displayed and analysed in a unified and centralized manner through intelligent, networked and informative means. The goal of being unattended during the refuelling and launching process is achieved, and the personnel at the test and launch positions are more capable. Compared with traditional launches, the smart launch site has truly achieved rapid preparation and one-click launch. The number of post personnel has been reduced by more than half, and the shortest single-launch task process can be shortened to 14 days, which is more suitable for high-density launches and emergency launch missions.
Zheng Taifeng, head of the tower of the smart launch site: The smart launch site of the Taiyuan Satellite Launch Center can currently carry out the launch of various types of launch vehicles from the Long March 6. After adaptive transformation, it can meet 7 different types of Long March 2 and Long March 4 series. Model launch vehicle launches capability. In the future rapid launch missions, the application value of the smart launch site will be brought into full play…

This mission is the 412th flight of the Long March series of launch vehicles.
Four hours before the launch of the rocket, all front-end operators evacuated the tower, and the rocket completed the subsequent launch process through unattended technology. The unattended technology of the Long March 6 rocket has achieved three “firsts” in my country in the field of delivery: the first use of automatic docking and filling technology, which can realize automatic filling of remote full-process propellants; The ground connector automatically falls off at the moment of take-off; after the first propellant filling, there is no personnel on duty at the front end of the launch site, which effectively ensures the safety of the rocket launch mission and is also the model’s firm practice of the “people-oriented” concept
“Tiankun-2” satellite successfully entered the predetermined orbit, the solar panels were deployed smoothly, the subsystems were in normal working condition, and the launch mission was a complete success. Chang Zheng Long March 6 modified carrier rocket successfully made its first flight The “Tian Kun 2” satellite is a new technology test satellite developed by the Space Engineering Company of the Second Academy of Aerospace Science and Industry of China. On March 3, 2017, the first satellite “Tiankun-1” independently developed by China Aerospace Science and Industry Corporation with completely independent intellectual property rights was successfully launched, expanding the spectrum of my country’s small low-orbit universal satellite platform. The “Tiankun-2” satellite inherits the characteristics of high functional density of the “Tiankun-1” satellite, and at the same time has a lower cost and a smaller size. It is another innovative achievement with a leading domestic level. Satellites have high functional density, strong mission capabilities, and good cost performance. They can meet the functional requirements of diverse and complex tasks such as space scientific exploration, in-orbit services, and new technology verification, and effectively improve the adaptability of small satellites to space multi-tasking.
The “Tiankun-2” satellite adopts an integrated design concept, with a highly integrated electronic unit as the core, and the platform and payload are tightly coupled. The main purpose of this experiment is to verify a number of key technologies such as new attitude and orbit control algorithms, multi-functional flexible cladding materials, and computational optical imaging….
中国空间站 On currently on December 2021, the Belt and Road InitiativeCNSA –China National Space Administration CSS China Space Station in which on a three to six months setting up a new home of the first three Shenzhou 13 in which spending up to on for the further construction and verifications of the systems of the CSS –China Space Station 2021 launch calendar in which currently the three Takionauts current Shenzhou 13 …… Preparations for the six months of extension of the China Space Station In which the currently it remains awaiting for the crew of setting up home in conducting fun scientifically onboard中国空间站.. China Space station …..
During this week of late March 2022 it’s the Countdown! The “Shenzhou 13” Takionauts who have been on business for the longest time are coming back soon
The three Takionauts of the Shenzhou Since this week, they have entered the stage of preparation for their return, let us look forward to their early victory!
The astronauts put the relevant equipment in place
Organize “rooms”
After entering the core module of the space station, the astronauts removed a lot of daily necessities and experimental equipment from the cargo spacecraft, and arranged a “small home” in the sky. Before going home, they need to restore the cabin environment as much as possible, such as fitness equipment, laboratory supplies, maintenance spare parts, etc., all need to be repackaged and put back in the designated location. In order to prevent the potentially dangerous floating and slipping phenomenon, some items also need to be fixed to the inner wall of the space station. In addition, they need to inventory and classify the remaining materials, so that the crew of the Shenzhou 14 spacecraft can “seamlessly switch” to life in orbit in the future.
packing luggage”
When the Takionauts are ready to go home, of course, they have to pack their “luggage”, which not only includes the things they can touch, but also “carries the data”. For half a year of “business trip”, the three astronauts carried out a number of experiments in the fields of space physics, life science, materials science, astronomical detection, etc. in the Tiangong Space Station. The scientific research value is very great, and the experimental data and records must be obtained from the core module of the space station.” “Transfer” to the return cabin of the Shenzhou 13 spacecraft and bring it back to the ground as soon as possible. In addition, the garbage accumulated in the space station in the past six months also needs to be “taken away”. Before the astronauts return, they need to do a thorough “cleaning” of the space station, and do a good job in collecting and sorting out. For example, residual food waste, sanitary product waste, and waste from on-orbit experiments all need to be packaged and sorted, put into the orbital cabin, and then plunged into the atmosphere with the orbital cabin and burnt out.
Takionauts work and live in the microgravity environment of the space station for a long time, and their bodies will undergo great changes, such as loss of body fluids, muscle atrophy, bone loss, and even immune system disorders. In order to alleviate the possible harm caused by these conditions, astronauts have to exercise in the space station every day, and they also need to perform intensive exercise before returning home, so as to make adaptations in advance for returning to the ground.
In addition , the zero-gravity physiological effect protection team at the Takionauts Ground Center will provide “exercise prescriptions” based on the real-time physical conditions of the three Takionauts. After they land safely, the ground professional team needs to carry out protection and isolation as soon as possible based on the previously accumulated data and real-time detection to help the astronauts recover their physical fitness and mental health and adapt to life on earth. At the same time, in order to welcome the three Takionauts back home safely, the Jiuquan Satellite Launch Center search and rescue team joined other search and rescue forces to conduct targeted training exercises at the Dongfeng Landing Field. It is reported that the current physical and psychological conditions of the three Takionauts in the Shenzhou 13 crew are better than expected, meeting the conditions for returning to Earth.
Looking forward to seeing the return capsule land safely at an early date
Familiar with the process
Although the technology is mature and reliable, the journey of the spacecraft’s return capsule to return to Earth is still full of dangers and challenges. Generally speaking, astronauts must be familiar with the necessary operations and contingency plans during the entire return process, such as when to separate the manned spacecraft from the space station assembly, when to start the thrusters, etc. In addition, they must carefully check the spacecraft’s return cabin to ensure that all systems are working properly, especially the spacecraft’s propulsion and power control systems.

“Turn off the lights and lock the door”
Just like a house that has been inhabited for a long time must be cut off from water and electricity, before Takionauts leave the space station, they also need to set the state of departure, and set up electricity, water, gas, communication and other aspects in place. According to domestic and foreign experience, they are likely to adjust a total of forty or fifty items to ensure that the space station can transmit effective parameters to the ground during subsequent unmanned missions. Before leaving, the astronauts have to close all the doors in the space station, and then return to the Shenzhou 13 spacecraft from the core module. After sitting down, fasten their seat belts and check the air tightness of the space suit and the integrity of the equipment. After everything is ready, just wait for the “departure”!
