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.

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.
On the 29th May 2021 Saturday Wenchang Spacecraft launch Center –Hainan Province –China – People’s Republic of China.. It was the successful launch of CNSA – China National Space Administration– China’s Tianzhou-2 cargo spacecraft in which was successfully launched on using a Long March- Chang Zheng 7 Medium Heavy Carrier Rocket.. in which the During this month of 16th May 2021 on a beautifully clear summery day it is the transfer of the advance Long March- Chang Zheng 7 Medium Heavy Carrier Rocket from Wenchang Spacecraft Launch Centre in Hainan Province – China – People’s Republic of China in which the Collaborative CNSA –China National Space Administration Belt and Road Initiative in which will be robotically assembled to form the China Space Station in which is a collaborative in between ESA- European Space Agency, ROSCOMMOS – UNOSA – United Nations for Office of Outer Space Affairs..
China launched the Tianzhou-2 cargo spacecraft at around 2055 hours Hong Kong -Beijing Time Saturday from Wenchang, southern China’s Hainan Province. The spacecraft, loaded with fuel, equipment and life supplies to sustain the Tiangong Space Station, is carried by the Long March-7 Y3 carrier rocket. As CGTN provide a special coverage gives you more details about Tianzhou-2 and China’s space station project…..
During the Docking procedures Space station and cargo spacecraft can be connected to the grid for power generation…According to the Eighth Academy of Aerospace Science and Technology, after the core cabin is successfully docked with the cargo spacecraft, in the combined flight mode, in order to ensure the power generation capacity of each cabin and the cargo spacecraft, the core cabin and the cargo spacecraft The cargo spacecraft will be connected to the grid for power supply. At that time, the core cabin can provide up to 2,000 watts of power to the cargo spacecraft. Although compared with the “big family” of the core cabin, the cargo spacecraft has only one third of the power supply capacity of the core cabin, but at critical moments, the cargo spacecraft can also provide about 1,000 watts of power to the core cabin.
“The core cabin supplies power to the cargo spacecraft, mainly considering that the cargo spacecraft is installed at the stern of the core cabin, and the cargo spacecraft’s solar battery wings are small in size and are easily blocked by other combinations of the space station. The cargo spacecraft supplies power to the core cabin for the purpose of Responding to the very few special situations that may occur in the future space station, this also demonstrates the flexibility and reliability of the power supply of the entire space station assembly.” Wang Zhenxu, chief designer of the power supply subsystem of the cargo spacecraft, introduced. In order to receive the 2000 watts of power gift from the core cabin, the cargo spacecraft itself needs to undergo a high-voltage grid-connected adaptation process. In response to the above problems, the developers of the Eighth Academy of Aerospace Science and Technology conducted a series of verification experiments to ensure that the normal operation requirements of the cargo spacecraft are met.
When the cargo spacecraft is connected to the core cabin for power supply, how to deal with the excess electricity? Developers have their own methods. Wang Zhenxu introduced that in the Tianzhou No. 2 cabin, a shunt regulator is installed, through which the excess electricity of the solar battery wing can be shunted. In the future, there will be the challenge of joint power supply of multiple combinations, but the power sub-system can always adapt. This is the intelligent management of the power sub-system in the space station era.
The newly advance variant of the Long March –Chang Zheng 7 Carrier Rocket has more than 130 improvements to make its performance better] This mission is the third launch of the Long March 7 carrier rocket. 4 years have passed since the Long March 7 Yao-2 launches. During this period, the model team Carried out a large number of optimized and improved designs, which not only realized the technological leap from “zero window” to “narrow window” launch, but also through more than 130 improvements such as simplifying and optimizing the on-board measurement system, and optimizing the tank pressurization design. The rocket has better performance and is more conducive to batch production and high-density launch.
Simplify and optimize the design of the on-arrow measurement system. The measurement parameters used for research have been deleted. The number of measuring points on the arrow has been reduced by about one-third, and the number of stand-alone measurement systems has been reduced by nearly half. This not only saves costs, but also helps to improve the sampling accuracy of some key parameters. In addition, this rocket also uses a high-rate Ka-band space-based measurement system. Compared with the S-band measurement system used by the Long March 7 Yao-2 launch vehicle, the transmission code rate has been increased by more than 20 times, realizing the full range of rocket flight telemetry. No blind spots.
Optimize the design of pressurization of the tank on the arrow. Combining the analysis of the results of the previous two flight tests, the booster reduces one tank booster gas cylinder without affecting normal use, and optimizes the boost pressure control bands of each module tank to increase the boost pressure. Utilization of gas. The rocket boost, the first-stage tail end and the first-stage transition section are changed from composite coating to ordinary coating. After the improvement, the construction process is simplified and the production cycle is shortened. Taking the first-level post-transition section as an example, the improved production cycle has been shortened from about 18 days to 13 days, laying the foundation for subsequent mass production. Focusing on zero-window launch, focusing on flight success or failure, sorting out one detail by one detail, fully identifying the weaknesses in the design and making improvements, in addition, drawing inferences about other rocket quality issues from the mechanism to ensure the complete success of this launch mission….

According to the space station construction plan, my country will launch the Shenzhou 12 manned spacecraft next month, and three astronauts will take the spacecraft to the core module. The three astronauts have to work and live in the core module for about three months. Therefore, they must prepare a variety of materials to facilitate their “clothing, food, shelter, transportation” and work in space. There are various daily necessities in the “express” sent by the number. The food on the space station can be described as a must-see in space, making people salivate from the sky. China’s aerospace food has many traditional Chinese dishes, with obvious Chinese characteristics. The food is not only divided into main and side dishes, but also pays attention to the combination of meat and vegetables, but also has unique flavours. Even the well-known shredded pork and kung pao chicken… all appear on the astronaut’s food list
