The two men will conduct a variety of experments during their 30 days on Tiangong 2, including taking ultrasound measurements for the first time in space, cultivating plants, and testing the three winners of an experimental design competition in Hong Kong for secondary students, according to Xinhua.

China provided little information about the mission until yesterday.

Although Chinese sources initially indicated this is the first of two two-man crews that will occupy Tiangong-2, more recent indications are that it will be the only one. The next launch to the small 8.6 metric ton space station is scheduled for April 2017. It is China’s first cargo resupply spacecraft, Tianzhou-1, which will be launched on a Long March 7 from the Wenchang Satellite Launch Center on Hainan Island. It reportedly will conduct a refueling test.
