China completes first space docking test

China has joined two space vehicles together in orbit for the first time.

The unmanned Shenzhou 8 craft, launched earlier this week, made contact with the Tiangong-1 space lab at 1729 GMT. The union occurred over China itself.

Being able to dock two space vehicles together is a necessary capability for China if it wants to start building a space station towards the end of the decade.
