Compared with the satellites and manned spaceships circling the earth, the spacecraft for lunar exploration has to endure more complex and more rigorous environment . Especially, the lunar surface environment may cause very severe problems, thus should be considered carefully in the design of spacecrafts and lunar rovers. A conceptual design of lunar surface environment simulation system was proposed. Most of the environmental factors, including lunar dust, geography, the compressibility and frictional effect of lunar regolith, hard vacuum, temperature variation, can be simulated simultaneously. The system may serve as the test facility of spacecraft and rover design, optimization and verification.
