CHINESE SHENZHOU 8 MISSION could last up to 3 weeks, apparently in preparation for a future manned mission.

The Shenzhou 8 spacecraft will fly with no crew on board, and will be sent to rendezvous and dock with China's Tiangong 1 space laboratory, expected to be launched at some time before Shenzhou 8 flies. The descent module of Shenzhou 8 will return to Earth at the end of the flight, carrying the experiment package.

Interesting. The space laboratory hasn’t been orbited yet, and the “manned” spacecraft will be unmanned. Why am I reminded of carts and horses?
