Shenzhou 12 (Chinese: 神舟十二号; pinyin: Shénzhōu shí'èr hào; lit. 'Divine Boat Number 12') was a Chinese spaceflight to the Tiangong space station, launched on 17 June 2021. It carried three People's Liberation Army Astronaut Corps (PLAAC) taikonauts on board a Shenzhou spacecraft. The mission was the seventh crewed Chinese spaceflight and the twelfth flight overall of the Shenzhou program. It was the first flight to Tiangong, and the first Chinese crewed spaceflight since Shenzhou 11 in 2016.
The Feitian space suit (Chinese: 飞天航天服; pinyin: Fēitiān Hángtiān Fù) is an extravehicular space suit design developed and used by the China Manned Space Program. It provides life support, environmental protection, and communications for taikonauts during extravehicular activity (EVA).
The earliest Feitian space suit was used on Shenzhou 7, worn by taikonaut Zhai Zhigang during China's first-ever spacewalk on 27 September 2008. An improved version of the Feitian space suit is used aboard the Tiangong space station, with the first EVA using the updated version being on Shenzhou 12's first EVA, on 4 July 2021.
