The three Chinese astronauts onboard the Shenzhou-14 spaceship entered the country's space station core module Tianhe on Sunday, according to the China Manned Space Agency (CMSA).

After Shenzhou-14 successfully completed a fast automated rendezvous and docking with the combination of the Tianhe module, the Tianzhou-3 cargo craft and the Tianzhou-4 cargo craft, the Shenzhou-14 crew entered the orbital capsule from the return capsule of the spaceship.

After a series of preparations, Chen Dong opened the hatch of the Tianhe core module. By 8:50 p.m. (Beijing Time), Chen Dong, Liu Yang and Cai Xuzhe had entered Tianhe one by one.

The trio will carry out relevant work as planned, the CMSA said.
