"The lunar dust environment simulator is a vacuum chamber. An electronic gun is installed outside the left of the chamber to produce electron beams to negatively charge lunar dust. There is a cellular structure composed of 36 deuterium lights in the front, used to produce ultraviolet rays to lunar dust to have low-voltage positive electricity. On the top is a vibrating screen designed to simulate flying dust on the lunar surface. The comprehensive lunar surface simulator, which can simulate multiple environments very close to the real state on the moon, helps us to the lunar dust formation mechanism in such an environment and its effects on spacecraft, space costumes and astronauts and prepare us for manned moon landing in the future."

"You can see our staff members are preparing for comprehensive tests of the equipment. At the experiment chamber, we can simulate six major kinds of environmental factors. It is an experiment facility that can simulate the most environmental factors and has the comprehensive performance most similar to the real space environment in the world. Through the simulation experiment facility, we can study the law of spatial environmental effects and explore the physical essence on the components of satellites and the materials and parts of various spacecraft."

A set of facilities, expected to contribute to China's space industry by simulating various space environments, have been put into trial operation in Harbin City of northeast China's Heilongjiang Province.

Developed by the Harbin Institute of Technology, the facilities can create an environment similar to the lunar surface in preparation for manned moon landing.

Scientists have made artificial micron-dimension dust with similar performance to that on the moon and Mars.

"The lunar dust environment simulator is a vacuum chamber. An electronic gun is installed outside the left of the chamber to produce electron beams to negatively charge lunar dust. There is a cellular structure composed of 36 deuterium lights in the front, used to produce ultraviolet rays to lunar dust to have low-voltage positive electricity.

The comprehensive lunar surface simulator, which can simulate multiple environments very close to the real state on the moon, helps us to the lunar dust formation mechanism in such an environment and its effects on spacecraft, space costumes and astronauts and prepare us for manned moon landing in the future," said Li Liyi, dean of the Institute of Space Environment and Material Science of the HIT.

Besides the lunar dust simulator, the facilities also include a chamber that can simulate radioactive environments.

"You can see our staff members are preparing for comprehensive tests of the equipment. At the experiment chamber, we can simulate six major kinds of environmental factors. It is an experiment facility that can simulate the most environmental factors and has the comprehensive performance most similar to the real space environment in the world.
