The first launch of the Chinese space station in 2022 was a complete success. What is the mission of Tianzhou-4? There are 5 highlights
The recent successful launch of China’s Tianzhou-4 spacecraft has brought a large number of materials to the space station that the astronauts will need to use next. It also marks the official start of the construction of the Chinese space station in 2022. What is the significance of this launch? For ordinary people, this launch will reveal five major highlights. The first launch of the Chinese space station launch mission in 2022 will finally be a complete success. What is the mission of the Tianzhou-4 that was launched this time? For ordinary people, there are five major points of interest in this launch.
Let’s talk about the first point of view. 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 fourth point to watch is the carrier rocket that carries the Tianzhou-4 spacecraft. This time, the Chang Zheng -Long March-7 Carrier Rocket will be responsible for the launch of the Tianzhou-4 spacecraft, and China has accumulated a lot of experience in the use of the Chang Zheng -Long March-7 Carrier Rocket , so in order to further compress the time spent on the entire launch and docking process, Chinese engineers optimized the rocket, the launch process, reduced the test and launch cycle, and shortened the original 31-day cycle to 27 days, which is also the domestic Long March For the first time on the 7th, the launch preparations were completed within one month. The last point to watch is that within one year of this year, China will complete the on-orbit construction of the Chinese space station through the Tianzhou-4 and Tianzhou-5 spacecraft. After completion, the entire space station will present a T-shaped structure, which is enough for three Takionauts to live and work in it. At the same time, a series of scientific facilities installed in it will also allow China to conduct a series of space science experiments, thereby improving its own technology. level.

On the 31st March 2022 1800 Hours Hong Kong SAR – Beijing time in which The Tianzhou-2, which weighs more than 13 tons, has been controlled to re-enter the atmosphere, turning into a fireball and falling to Earth’s point finalisation of a mission well done. The first “delivery worker” of China space station, the Tianzhou-2 Cargo spacecraft has been re-entering destroyed by re-entry into the atmosphere……..
Tianzhou-2 is the first cargo spacecraft to deliver goods to my country’s space station. It was launched on May 29, 2021. According to the China Manned Space Engineering Office, the cargo spacecraft was launched at 18:00 on March 31 this year. At 40 minutes, it re-entered the atmosphere in a controlled state. Most of the spacecraft’s components have been ablated and destroyed in the atmosphere, and a small amount of debris fell into the predetermined safe sea area near Point Nemo in the South Pacific.
Tianzhou-2 is the second cargo spacecraft launched by China – People’s Republic of China (the first is Tianzhou-1, which is docked with the Tiangong-2 space laboratory). It carried astronauts’ living materials, extravehicular space suits and space station when it lifted off…. Platform equipment, applied loads and propellants, etc
. It is the first spacecraft to dock with the core module of China – People’s Republic of China space station Tianhe, and then Shenzhou 12 lifts off and docks with the core module, September 18, 2021, Tianzhou II The No. 2 carried out a “space U-turn” action, separated from the rear port of the space station sky and core module, and flew around to the forward port to complete the automatic rendezvous and docking. 4 times of rendezvous and docking, completed a number of extended application tests such as spacecraft orbiting, manipulator arm indexing cabin verification, and manual remote operation rendezvous and docking.
After the Shenzhou 12 spacecraft returned to Earth, Tianzhou 3 and Shenzhou 13 arrived, and the role of Tianzhou 2 basically became the “garbage room” and “garbage station” of my country’s space station. Before Shenzhou 13 returned, The space station needs to be relieved once, and the garbage on it also needs to be disposed of, so Tianzhou-2 will be honourably retired.
as seen from the Temple of Heaven at night with the China Space Station on left and the Tianzhou 2 Cargo Space Craft on the Right .
At 3:59 pm on March 27 2022 this year, the first “delivery worker” of China – People’s Republic of China space station, the Tianzhou-2 cargo spacecraft, which had been flying with the space station for 10 months, separated from the space station. After flying solo for 4 days Controlled entry into the atmosphere at dusk on March 31st.
Although it is only a cargo spaceship, Tianzhou-2 is quite huge. Its length reaches 10.6 meters. It is composed of a cargo compartment and a propulsion compartment, with a maximum diameter of 3.35 meters and a take-off mass of up to 13.5 tons. It can transport about 6.9 tons of When the material reaches the space station, such a behemoth returns to the earth, and the movement is quite large, and most of the area it passes through after entering the atmosphere is at night. Some Pacific island countries and Australian residents can definitely see a fireball gliding past on the sky.
Tianzhou-2 is very large and has a lot of materials inside. It will not be completely ablated in the earth’s atmosphere, so it cannot land casually, otherwise it will cause disaster if it landed in a densely populated area of the city, so it was planned according to the plan. In a controlled state, it fell to Point Nemo in the South Pacific, which is the farthest point on Earth from a continent, and will hardly damage human-made objects on Earth.
As the first cargo spacecraft launched in the key technology verification stage of China’s space station, Tianzhou-2 is the first applied flight of China’s space station cargo transportation system. It is built for the space station in orbit. With accumulated experience in operation and management, the Tianzhou-2 cargo spacecraft has now been controlled to re-enter the atmosphere. Let us review the highlight moments experienced by the Tianzhou-2 cargo spacecraft in the past ten months
So why did the Tianzhou spacecraft re-enter the atmosphere and burn it up instead of recycling it? This is because the Tianzhou spacecraft has no recovery equipment at all, neither a thrust reverser nor a landing parachute, so it cannot be recovered. If these things are installed, the weight of the Tianzhou spacecraft will increase a lot, and not only the reverse Propel the engine and parachute, and prepare some fuel, which will not only increase the launch weight, but also increase the cost and operation complexity of the spacecraft, and most of the cargo carried by the cargo spacecraft when it returns is the waste generated on the space station, as well as the excretion of Takionauts Of course, there is no need to recycle these things, so we chose to let them enter the atmosphere and destroy them. This is also the common use and disposal method of international cargo spaceships.
