The last piece of China's space laboratory, the Shenzhou-11 manned spacecraft, is due to arrive at the Jiuquan Satellite Launch Center on Saturday noon.

China's second orbiting space lab Tiangong-2 will be launched in September. And the Shenzhou-11 will carry two astronauts into the space in the following month, and then dock with Tiangong-2. This will be China's last manned mission before it finishes building its own space station.

The space station will be comprised of one command module and two experiment modules. It's designed to operate for at least 10 years starting in 2022. It will house three full-time astronauts and up to six during rotation periods.
