Chinese space truck "Tianzhou-4" undocked from the orbital station of the People's Republic of China

China's Tianzhou-4 space truck on Wednesday began a controlled return to the Earth's atmosphere after undocking from the Chinese Tiangong orbital station.

This was reported by the Administration of the Manned Space Flight Program of the People's Republic of China.
"The Tianzhou-4 cargo spacecraft, having completed its planned tasks, successfully undocked from the space station and entered the stage of independent flight," the agency said in its account of the Vichat social network. "Currently, the Tianzhou-4 is in good condition, the truck is returning to the Earth's atmosphere in a controlled manner."
The Tianzhou-4 cargo spacecraft was launched into orbit on May 10 from the Wenchang Cosmodrome on Hainan Island. He delivered about 6 tons of cargo to the space station. He will be replaced in the near future by the Tianzhou-5 truck, which has already been delivered to the Hainan cosmodrome.
On October 31, China launched the second laboratory module to the national space station, after which it assumed its final T-shape. The station will have to pass functional tests. At the moment, the orbital complex consists of the Tianhe base module, the Wentian and Mengtian laboratory modules, as well as the Shenzhou-14 manned spacecraft. The crew of the latter arrived at the station in early June and is expected to stay there until the end of December.
According to the plan, after the launch of Tianzhou-5, the launch of the Shenzhou-15 manned spacecraft will take place by the end of the year. It is expected that for some time the two crews will be at the station together, after the shift, the Shenzhou-14 taikonauts will return to Earth.
The Chinese station is located at an altitude of about 400 km and will last more than 10 years. It is designed for three people (up to six for a short time when the crew changes). The mass of the T-shaped complex, which has three docking nodes and a gateway for entering space, is 66 tons, the volume of compartments reaches 110 cubic meters. It is expected that the orbital object will work normally by the end of 2022 and, as promised by the Chinese authorities, will be available for international projects, writes TASS.
