A few hours ago, the three Chinese taikonauts of the Shenzhou 15 mission returned to Earth after spending a little more than six months on the Chinese space station Tiangong. The three taikonauts Fei Junlong, Deng Qingming, and Zhang Lu had left the station a few hours earlier to land at a site called Dongfeng in China’s Inner Mongolia Autonomous Region. A procedure that significantly reduces the time to return to Earth already tested in the past worked again and is becoming routine.
