The Wentian laboratory cabin module (simplified Chinese: 问天实验舱; traditional Chinese: 問天實驗艙; pinyin: Wèn tiān shíyàn cāng; lit. 'Quest for the Heavens laboratory cabin module'), is a major component of the Tiangong space station. It is the first of the station’s Laboratory Cabin Modules and the first module added to the Tianhe core module.
Wentian was launched on 24 July 2022 from the Wenchang Spacecraft Launch Site and docked with Tianhe later that day. The crew of Shenzhou 14 entered the module for the first time a few hours later. On 30 September 2022, the module was relocated to the starboard port by the station’s indexing robot arm to prepare for the arrival of the Mengtian.
