China’s Shenzhou 15 astronauts arrive at Tiangong Space Station on historic mission

A fresh crew of three Chinese astronauts have joined three others on the Tiangong Space Station, after their Shenzhou 15 spacecraft arrived ahead of the first in-orbit crew rotation in Chinese space history. The mission was also a milestone for Tiangong, which will be the second permanently inhabited outpost in space along with the International Space Station (ISS), led by US space agency Nasa. US lawmakers excluded China from ISS missions in 2011 over concerns about national security.
