The Tianzhou series cargo spacecraft mainly had the following functions: 1. Material supply: provide various supplies for the China space station during its in-orbit operation, including astronauts 'living materials, extraterrestrial spacesuits and extraterrestrial consumables, and space station platform materials. For example, transporting necessities for the Shenzhou 15 astronauts during their six-month stay. 2. Equipment Transportation: responsible for transporting all kinds of equipment and components needed for the construction and operation of the space station to ensure the normal operation of the space station. 3. "Fueling: Able to replenish fuel for the space station. Because the space environment will reduce the orbit of the space station even if the gas is thin, the fuel replenishment can greatly extend the service life of the space station. 4. Payload Carrying: It can carry multiple payloads for scientific experiments and verification, and support on-orbit scientific experiments. 5. It laid the foundation for manned space missions. For example, after the rendezvous and docking of Tianzhou-3 with the Tianhe core module and Tianzhou-2 combination, it would enter the three-module (ship) combination flight state, laying the foundation for the follow-up flight mission of the space station in orbit, meeting the mission requirements of the Shenzhou-13 rendezvous and docking and the conditions for astronauts to enter.

Tianzhou 2 had returned. On March 27,2022, Tianzhou-2 evacuated the core module assembly of the space station. At 18:40 on March 31, the Tianzhou-2 cargo spacecraft entered the atmosphere under control. Most of the spacecraft's components were burned and destroyed, and a small amount of debris fell into the South Pacific Ocean. The novel " Hundred Years of Spaceship " is equally exciting.

The Tianzhou-2 cargo spacecraft was developed by the Fifth Academy of China Aerospace Science and Technology Corporation. It was the first cargo spacecraft launched during the key technology verification phase of the China Space Station. It was a two-compartment configuration consisting of a cargo compartment and a propulsion compartment. It had a total length of 10.6 meters, a maximum diameter of 3.35 meters, a maximum take-off weight of 13.5 tons, an upstream material capacity of 6.9 tons, a cargo ratio of 0.51, an in-orbit life of no less than one year, a power supply capacity of no less than 2700 volts, and an all-phase autonomous rendezvous and docking capability. It could complete the in-orbit replenishment of propellants many times. In order to carry more supplies, a total of 26 different size and shapes of packages were designed. In January 2021, it passed the factory review. On May 16, it was transported to the launch area with the Long March 7 remote three launch vehicle combination. On May 29, it was launched into orbit at the Wenchang launch site in Hainan, sending 6.8 tons of supplies to the space station, carrying three months of consumables, extraterrestrial spacesuits and platform materials for three astronauts and docking with the core module. At 21:17 on the day of the launch, the two wings of the solar panels were successfully launched and the launch was successful. On May 30, it completed the autonomous rapid rendezvous and docking with the Tianhe core module, and on September 18, it completed the detour and forward rendezvous and docking. The core module assembly of the space station was evacuated on March 27,2022. At 18:40 on March 31, it entered the atmosphere under control. Most of the components were burned and destroyed, and a small amount of debris fell into the designated safe waters of the South Pacific. During the in-orbit operation, it had carried out four rendezvous and docking with the Tianhe core module. According to the plan, it completed many expansion application tests such as spacecraft orbit, mechanical arm displacement module verification, manual remote operation rendezvous and docking, etc. After separating from the space station, it successfully implemented a two-hour rapid rendezvous test between the cargo spacecraft and the space station, accumulating experience for the on-orbit construction and operation management of the space station.

Tianzhou VII had withdrawn from the space station assembly at 16:30 on November 10, 2024 and entered the independent flight phase. It would choose a controlled re-entry into the atmosphere in the near future. Most of its components would be destroyed during the re-entry process, and a small amount of debris would fall into the designated safe waters of the South Pacific Ocean. Therefore, it could be said that Tianzhou VII was about to end its mission. The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!

Tianzhou-2 entered the atmosphere at 18:40 on March 31,2022 Beijing time. Most of the spacecraft's components were burned and destroyed, and a small amount of debris fell into the South Pacific. Tianzhou-2 flew in orbit for ten months and successfully completed all the established tasks, including transporting 6.8 tons of materials to the space station for the Shenzhou-12 mission, completing several key technology verification missions, and successively carrying out four rendezvous and docking with the space station core module assembly. The spacecraft flew around as planned, the robotic arm moved the module segment verification, the manual remote operation rendezvous and docking, and many other extended application experiments.
