China Launches Supply Ship to Tiangong-2 Space Station

China launched its Tianzhou-1 cargo ship aboard a Long March 7 booster on Thursday.

The supply ship is headed for an automated docking with the Tiangong-2 space station, which does not have a crew on board. Two Chinese astronauts occupied the station for 30 days last fall.

Tianzhou-1 will rendezvous and dock with the space station three times. The supply ship, which is larger than the space station, will also test out refueling procedures crucial for a permanent, multi-module space station China plans to begin launching in 2018.
