Description:

TIANZHOU-3 is a Chinese mission to conduct the on-orbit refueling of the Tiangong-2 space station. At the end of the mission, Tianzhou-3 will make an automatic destructive reentry into Earth′s atmosphere.

Mission details:

On top of the Long March-7 Y4, China successfully launched an unmanned cargo spacecraft Tianzhou-3 on September 20, 2021, to supply supplies for its under-construction space station Tiangong, which is expected to be finished following year.
The Tianzhou-3 mission was the fourth of 11 planned flights to construct China′s three-module space station. It followed the famous Shenzhou-12 mission, in which three astronauts spent a record 90 days in the China′s space station core module before safely returning to Earth. Onboard the Tianzhou-2, there were 6.8 tonnes of supplies, including 160 packages of commodities and two tonnes of propellants, and one of the most costly items onboard the Tianzhou-3 would be a 90-kilogram spacesuit particularly developed for spacewalk missions.
