[Tianzhou-7 ship-rocket assembly transferred to launch area]
According to the China Manned Space Engineering Office, on January 12, 2024, Beijing time, the Tianzhou-6 cargo spacecraft successfully evacuated the space station assembly and entered the independent flight stage. On January 15, the Tianzhou-7 ship-rocket assembly will be transferred, and the assembly will enter the launch area in a vertical transfer manner. Follow the live broadcast and cheer for China Aerospace.
At around 08:00 on January 15, 2024, the movable launch platform carrying the “Tianzhou 7” cargo spacecraft and the “Long March 7” Ya8 launch vehicle combination was launched from the Wenchang launch site vertical assembly test plant at 10:40 After arriving at the launch area, the “Tianzhou-7” launch mission entered the refueling launch stage.
At present, the facilities and equipment at the Wenchang Space Launch Site are in good condition. Various functional inspections and joint tests before launch will be carried out as planned. The launch is planned to be carried out in the near future
The “Tianzhou 7” spacecraft is the second batch of products in the “Tianzhou” series of cargo spacecraft. A total of 6 spacecrafts from “Tianzhou 6” to “Tianzhou 11” were developed and produced in this batch. “No. 7” is the second spacecraft among them. “Tianzhou 7” is an improved cargo spacecraft of “Tianzhou”, with cargo space and load capacity further improved. Its pressurized cargo hold has a loading volume of 22.5 cubic meters, a loading capacity of 6.7 tons, and the cargo loading capacity of the entire ship reaches 7.4 tons. , the upward cargo load ratio is 0.53.
After entering the launch area, the “Tianzhou-7” mission ship rocket will complete various launch preparations represented by the joint training of the whole area, and then add propellant and enter the ready-to-launch state. It is expected that at about 22:00 on January 17, the “Tianzhou-7” spacecraft will be launched from the 201 station of the Wenchang launch site by the “Chang-7” Yao-8 rocket. The spacecraft will use the rapid rendezvous and docking mode to ascend and dock with the Chinese Space Station. Tianhe’s core cabin has a rearward port.
The “Tianzhou-7” mission is the sixth cargo launch mission of the space station mission. It is also the first launch mission of China’s manned space project in 2024, and the world’s manned space launch mission will also kick off.
“Careful organization and implementation to ensure complete success”
At this moment, the Tianzhou-7 cargo spacecraft and the Long March-7 Ya8 launch vehicle and arrow assembly are being transported vertically to the launch area.
[New Commander 01 at Wenchang Space Launch Site] In the Tianzhou-7 cargo spacecraft mission, He Hongye will serve as Commander 01. This will be his first time holding the position of Commander 01, and he will also become the first manned commander in history. He is the fourth 01 commander in the space launch mission and the third 01 commander in the Tianzhou cargo spacecraft launch mission.
On the 21st December 2023 Hour Hong- Kong SAR – Beijing time CNSA –China National Space Administration On May 10th 2023 , the combination of the Chang Zheng Long March 7 Yao 8 carrier rocket has safely arrived at the Wenchang Space Launch Site…… According to the China Manned Space Engineering Office, the Long March-7 Yao-8 carrier rocket that will carry out the Tianzhou-7 launch mission has completed all development work before leaving the factory and will be launched in 2023.
It was safely transported to the Wenchang Space Launch Site on December 21, 2023. After that, the Long March 7 Yao 8 launch vehicle will carry out final assembly and testing at the launch site together with the Tianzhou 7 cargo spacecraft that has arrived in advance. At present, all participating systems in the launch site area are steadily preparing for missions as planned….
Tianzhou 7 arrives in Wenchang! Expected to launch in January 2024
Recently, after completing the work related to leaving the factory, the “Tianzhou 7” cargo spacecraft has arrived at the Wenchang Space Launch Site in Hainan Province, China, People’s Republic of China. Subsequent final assembly, testing and other work will be carried out as planned. Preparations for the launch site for the next cargo supply mission are underway as planned. Expand.
It is expected that in January 2024, the “Tianzhou-7” cargo spacecraft will be launched by the “Long March 7” Yao-8 carrier rocket. The spacecraft will ascend using the rapid rendezvous and docking mode and dock behind the “Tianhe” core module of the Chinese Space Station. Send a new batch of cargo supplies to the port for the “God Seventeen” mission. Before the “Tianzhou-7” spacecraft goes up, the “Tianzhou-6” spacecraft will unlock and separate from the rear port of the “Tianhe” core module, freeing up the docking port for the former.
The “Tianzhou-7” cargo spacecraft is the second in a new batch of “Tianzhou” spacecraft. This batch has developed and produced six spacecrafts, “Tianzhou-6” to “Tianzhou-11”. Compared with the “Tianzhou-5” spacecraft in the previous batch, the “Tianzhou-7” spacecraft has undergone system upgrades and greatly improved the cargo compartment. The cabin volume has increased by 20% and the transportation capacity has increased by about 500. Kilogram, the maximum transport capacity has been increased from the previous 6.9 tons to about 7.4 tons, and the materials provided to astronauts will be able to support longer missions. Based on the increase in transportation capacity, the launch density of the space station mission “Tianzhou” cargo spacecraft has been adjusted from the previous 2 times/1 year to 3 times/2 years, with an average of one launch mission every 8 months, and the subsequent launch density will be further reduced.

The “Tianzhou-7” cargo spacecraft adopts a dual-cabin tandem configuration, with a propulsion cabin and a cargo cabin from bottom to top. The total length of the spacecraft is 10.6 meters, the maximum diameter of the main body (cargo compartment) is 3.35 meters, the dry mass is 6.5 tons, the maximum upward transport capacity is 7.4 tons, and the cargo-cargo ratio reaches 0.53. The “Tianzhou” improved cargo spacecraft is the spacecraft with the strongest transportation capacity, the highest cargo load ratio, and the most comprehensive on-orbit support capabilities among the world’s active cargo spacecraft.
Since the establishment of the space station, the launch missions of China’s manned space project have entered a normalized stage, with 2 manned launch missions and 1 to 2 cargo launch missions being carried out on a regular basis every year. According to the plan, China’s manned space program will carry out four launch missions in 2024: “Tianzhou 7”, “Shenzhou 18”, “Tianzhou 8” and “Shenzhou 19”. Among them, “Tianzhou 7” “No. 1” mission will take the lead.
