Mengtian (simplified Chinese: 梦天; traditional Chinese: 夢天; pinyin: Mèng Tiān; lit. 'Dreaming of the Heavens[4]'), officially the Mengtian laboratory cabin module (Chinese: 梦天实验舱), is a major module of the Tiangong space station. It is the second Laboratory Cabin Module launched, after Wentian, and the second module to extend the existing Tianhe core module of the station.[5] It was launched into orbit from the Wenchang Spacecraft Launch Site on 31 October 2022,[6] successfully docking with Tianhe forward port at 20:27 UTC on the same day.[7]
On 3 November 2022, Mengtian was relocated to the larboard port at 01:32 UTC[8] by indexing robot arm. On the same day at 07:12 UTC, the crew of Shenzhou 14 opened the hatch and entered the module for the first time.
