China Launches Its Most Powerful Rocket Yet

New rocket will be crucial in servicing a planned space station.

— -- China successfully launched its Long March 7 rocket over the weekend in a key test that will pave the way for a planned space station set to become operational by 2022.

Blasting off from the Hainan Wenchang Space Launch Center in southern China, the 53-meter rocket carried a mock-up of China's next generation crew spacecraft so officials could find out how the vessel fared during re-entry. The new vehicle could one day be used to help service the China's future space station.

"It was designed to collect aerodynamic and heat data for a re-entry capsule, to verify key technologies such as detachable thermal protection structure and lightweight metal materials manufacturing, and to carry out blackout telecommunication tests," China's space program said in a statement.

The 53-meter Long March 7 is the middle child in a trio of new Chinese rockets. The Long March 5 is a heavy-lift launch system while the Long March 6 is designed to carry lighter satellites into orbit.
