Mission Details

Tianzhou 7

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 its future modular space station. It was first launched (Tianzhou 1) on the Long March 7 rocket on April 20, 2017, and demonstrated autonomous propellant transfer (space refueling).

The Tianzhou cargo ship has several notable differences from the Tiangong stations from which it is derived. It has only three segments of solar panels (against 4 for Tiangong) but has 4 maneuvering engines (against 2).

Classically, the Tianzhou space freighter consists of two subassemblies: 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.
