China successfully launched its first human spaceflight mission in more than three years Oct. 16, placing into orbit a spacecraft carrying two astronauts that will dock with a new space laboratory module.
 
Shenzhou-11 is scheduled to dock with the Tiangong-2 module Oct. 18. That module, launched Sept. 15, will host the crew for 30 days, twice as long as the existing Chinese human spaceflight endurance record, set by the Shenzhou-10 mission in June 2013. That mission was also the last Chinese human spaceflight prior to the Shenzhou-11 mission.
 
During the 30-day mission, Jing and Chen will carry out a number of medical and space science experiments, as well as test various systems on the Tiangong-2 module. They will also engage in public outreach activities, including serving as “special correspondents” for the state-run Xinhua news service.
 
The mission is part of Chinese efforts to develop a permanent space station. Chinese officials have indicated that they expect this station, consisting of several modules but smaller than the International Space Station, to be completed by the early 2020s.
