China's cargo spacecraft Tianzhou-3 separated from the country's space station core module Tianhe and redocked with the module on Wednesday.
Tianzhou-3 detached from the rear docking port of Tianhe at 5:02 a.m. (Beijing Time), moved to the module's front port and completed a computer-orchestrated rendezvous and docking at 9:06 a.m., according to the China Manned Space Agency.
It also said the combination of Tianhe and Tianzhou-3 is in good condition, waiting to dock with the Tianzhou-4 cargo craft, the Shenzhou-14 manned spaceship and the lab module Wentian.
China plans to complete the in-orbit construction of its space station by the end of 2022.
A total of six missions are planned for this year, including the launch of the Tianzhou-4 cargo spacecraft in May, the Shenzhou-14 manned spacecraft in June, the lab module Wentian in July, and the lab module Mengtian in October.
The three modules will form a T shape to complete the in-orbit construction of China's space station.
