BEIJING, July 8 (China Space News) -- Chinese scientists have made a breakthrough in cryogenic rocket engine technology that can extend the orbital period of rockets from a few hours to 30 days, providing support for China's future deep space exploration.

Cryogenic rocket engines are specially designed to work at extremely low temperatures. They use non-toxic and non-polluting propellants, such as liquid hydrogen and liquid oxygen, which are more cost-efficient than others.

The engine has been widely used in domestic and foreign launch vehicles, including China's Long March-5 and Long March-7 carrier rockets.

Scientists from the China Academy of Launch Vehicle Technology have developed two insulating materials that can reduce propellant evaporation loss and keep rockets in flight for longer than before.

The material technology breakthrough realizes long-term storage of cryogenic propellant in orbit, proving its readiness for China's future deep space exploration and long-distance space transportation.
