"The astronaut crew will stay in space for several months. During this period, we will verify the new technologies of the space station, including its spacewalk, robotic arms, and energy technologies," Zhou added.
China's ambitious space program includes plans for a lunar station by 2045 and a commercial launching service.
On December 6, the Chinese Chang'e 5 probe, which carried samples of the lunar surface to bring them to Earth, was docked in the lunar orbit. This was a new achievement for China's space program.
