☑️ 3rd Long March 7 mission this year, 20th overall

Sourced from NextSpaceflight

The Tianzhou (Chinese: 天舟; lit. 'Heavenly Ship') is a Chinese automated cargo spacecraft developed from China's first prototype space station Tiangong-1 to resupply the Chinese Space Station.

Classically, the Tianzhou space freighter consists of two sub-assemblies: the service module in which the propulsion, energy system, and various equipment necessary for the operation of the spacecraft are located, and the orbital module containing the cargo.

The service module is similar to the service module of Tiangong 1 with some modifications: a larger number of propellant tanks, and a more powerful propulsion system. The module is 3.3 meters long and has a diameter of 2.8 meters. The main propulsion used for orbital maneuvers consists of 4 rocket engines with a unit thrust of 490 newtons.

The cargo module is 5 meters long and has in its basic version a pressurized bunker to transport cargo with a volume of 15 m3. The front part is equipped with an APAS-type hatch that allows electrical connections to be made, as well as 4 pipelines used to transfer fluids to the space station's tanks.
