China on Saturday launched the crewed spaceship Shenzhou-13, sending three taikonauts, or Chinese astronauts, to its space station core module Tianhe on a six-month mission. The three astronauts are Zhai Zhigang, the commander and China's first spacewalker, Wang Yaping, the first Chinese female astronaut to visit China's space station and carry out extravehicular activities, and Ye Guangfu, a newcomer to space.
