The docking to the station’s main module Tianhe occurred at 03:13 local time on Monday (19:13 GMT on Sunday), about 13 hours after Wentian was launched.
In a later update on Monday, CMSA said that the Shenzhou-14 crew currently at the orbital station, successfully entered the Wentian module at around 10:03 local time (02:03 GMT on Monday), seven hours after its docking.
The lab module was launched using the Long March 5B carrier rocket on Sunday, from the Wenchang Space Launch Site on Hainan. The module consists of three parts: the working compartment, the airlock compartment, and the resource compartment.
Wentian, which is 17.9 meters (55.7 feet) long, has a maximum diameter of 4.2 meters and a launch weight of 23 tons, is currently the largest spacecraft launched by China.
China launched the Long March 5B carrier rocket with the Tiangong orbital station’s main module Tianhe ("Harmony of the Heavens") at the end of April, 2021. Tianhe will be the control hub for the Tiangong ( "Heavenly Palace") orbital station.
China expects to finish assembling its first space station in lower Earth orbit this year.
