- Summary- Shenzhou-15 marks last of 11 missions since April 2021 in building of space station- Shenzhou-15 crew to take over from Shenzhou-14 astronauts on space station- Chinese space station to be second permanently inhabited outpost after NASA-led ISSBEIJING, Nov 30 (Reuters) - Three Chinese astronauts arrived on Wednesday at China's space station for the first in-orbit crew rotation in Chinese space history, launching operation of the second inhabited outpost in low-Earth orbit after the NASA-led International Space Station.The spacecraft Shenzhou-15, or "Divine Vessel", and its three passengers lifted off atop a Long March-2F rocket from the Jiuquan Satellite Launch Centre at 11:08 p.m. (1508 GMT) on Tuesday in sub-freezing temperatures in the Gobi Desert in northwest China, according to state television.Shenzhou-15 was the last of 11 missions, including three previous crewed missions, needed to assemble the "Celestial Palace", as the multi-module station is known in Chinese.The Shenzhou-14 crew, who arrived in early June, will return to Earth after a one-week handover that will establish the station's ability to temporarily sustain six astronauts, another record for China's space programme.While still in its infancy compared with NASA's technologies and experience, China's space programme has come far since the mid-20th century, when the country's late leader Mao Zedong lamented that China could not even launch a potato into orbit."
