Module of the Tiangong space station / From Wikipedia, the free encyclopedia

Wentian (simplified Chinese: 问天; traditional Chinese: 問天; pinyin: Wèn Tiān; lit. 'Quest for the Heavens[5]'), officially the Wentian laboratory cabin module (simplified Chinese: 问天实验舱; traditional Chinese: 問天實驗艙), is a major module of the Tiangong space station. It is the first Laboratory Cabin Module launched, and the first module to extend the existing Tianhe core module of the station. It was launched into orbit from the Wenchang Spacecraft Launch Site on 24 July 2022,[1] successfully docking with Tianhe forward port at 19:13 UTC on the same day.[4] On 25 July 2022 at 02:03 UTC, the crew of Shenzhou 14 opened the hatch and entered the module for the first time.
