Introduction to Tianzhou Satellite
You might have some misunderstandings. The Tianzhou series is a cargo spacecraft, not a satellite. Tianzhou-1 was launched on April 20, 2017. It was the first cargo spacecraft independently developed by the China Aerospace Science and Technology Corporation's Institute of Space Technology. It was the ground logistics support system for cargo transportation to Tiangong-2, and it was also the finale of the second step of China's manned space project's three-step strategic plan. On April 22, 2017, it completed its first docking with Tiangong-2. On September 22 of the same year, it entered the atmosphere and burned after completing the mission. Tianzhou VII was launched on January 17, 2024, carrying more than 260 pieces of cargo, with a total weight of about 5.6 tons. On November 10, 2024, it left the space station and entered the independent flight phase. It was about to enter the atmosphere and burn down. It had the characteristics of carrying a wide variety of goods and a large number of large goods. It had been in orbit for nearly 10 months, setting a record for the Tianzhou series of spacecraft in orbit. In addition to replenishing supplies, it also took on the task of cleaning up waste. Tianzhou-8 successfully evacuated the China Space Station on November 10,2024 and entered the independent flight phase. It would enter the atmosphere in the near future. In addition, according to the plan, the Tianzhou-9 cargo spacecraft mission would be implemented in 2025. The novel " Hundred Years of Spaceship " is equally exciting.
