Both the ship and its Long-March 2-F rocket have been moved to the Jiuquan Satellite Launch Center in the Gobi desert.
The latest Shenzhou mission will carry three astronauts to the experimental space module of Tiangong-1.
It's been confirmed the new crew will have completely different members with its predecessor.
This time, the three astronauts will give a special lesson from the module to a group of students.
Once in orbit, the Shenzhou 10 will link up with the experimental module, which was moved into position last month.
Rendezvous and docking exercises between the two vessels are part of China's efforts to build a space station by the year 2020.
The Shenzhou-10 will be China's fifth manned space mission since 2003, when astronaut Yang Liwei became the country's first person in orbit.
China is also planning an unmanned moon landing and deployment of a moon rover.
Scientists have talked about the possibility of sending a man to the moon, but this is not likely to happen before 2020.
