China’s development of the first cargo spacecraft “Tianzhou No.1†was a complete success!
Electronic enthusiasts eight o'clock in the morning: April 20th (Yang Xin, Xiao Jianjun) At 19:41 on April 20, the Long March 7 remote launch vehicle carrying the Tianzhou-1 cargo spacecraft was fired at the Wenchang Space Launch Site in China. After about 596 seconds, the spacecraft and the rocket were successfully separated and entered the orbit. The launch was a complete success.
The first cargo spacecraft independently developed by China, "Tianzhou No. 1", was launched at the Hainan Wenchang Space Launch Site at 19:41 on the evening of April 20. (video screenshot)
This is the first flight test of the space station cargo transportation system consisting of the Tianzhou cargo spacecraft and the Long March 7 carrier rocket. After the spacecraft is in orbit, it will carry out automatic rendezvous and docking, automatic rendezvous and docking and other three rendezvous and docking, three times of propellant on-orbit replenishment, space application and space technology, etc. according to the predetermined procedure. A number of real (test) tests. During the period, Tianzhou No. 1 and Tiangong No. 2 were in orbit for about 2 months, and Tianzhou No. 1 was flying independently for about 3 months. After the completion of the scheduled tasks, Tianzhou No. 1 will be controlled to derail and fall to the predetermined safe sea area; Tiangong No. 2 will continue to carry out expansion tests and applications.
At present, Tiangong No. 2 runs on a nearly circular docking track 393 kilometers away from the ground. The equipment works normally and the running condition is good, meeting the requirements of the rendezvous and docking mission.
The Long March 7 remote two launch vehicle is basically in line with the technical status of the Long March 7 remote launch vehicle that performed the first flight mission. In order to meet the requirements of launching the cargo spacecraft, some technical status changes were made to further improve safety and reliability. This is the 247th flight of the Long March series of launch vehicles.
