China’s Tianzhou-1 cargo spacecraft and Tiangong-2 space lab completed their first in-orbit refueling at 7:07 p.m. Thursday, another success of the Tianzhou-1 mission.
Mastering the technique of refueling in space will help the country to build a permanent space station.
China is the third country, besides Russia and the United States, to master refueling in space.
The in-orbit refueling, under control of technicians on Earth, takes about five days.
A second refueling in space will be conducted in June.
Tianzhou-1, China’s first cargo spacecraft, was launched on April 20 from Wenchang Space Launch Center in south China’s Hainan Province.
It completed automated docking with the orbiting Tiangong-2 space lab on April 22.
