BEIJING, Dec. 1 (China Space News) — China is conducting tests on its largest and most powerful rocket, the Long March 5, at the Wenchang Satellite Launch Center in Hainan province.

The Long March 5 is the most sophisticated rocket that Chinese designers have developed. The rocket will use liquid oxygen/kerosene and liquid oxygen/liquid hydrogen as propellants for its engines, which means the gigantic craft will be more environmentally friendly than previous designs.

The Long March 5 will be used to launch large lunar probes and the manned space station that China plans to send into orbit around 2020.
