The three taikonauts Fei Junlong, Deng Qingming and Zhang Lu arrived at the space station „Tiangong“ on Wednesday. They docked with the „Shenzhou-15“ at the space station and are now expected to spend about a week together with their three colleagues, who have already been living and working at the station for half a year and are now being relieved. The six-month mission of the „Shenzhou-15“ is to be the last in the construction phase of the „Heavenly Palace“.
