On an orbit over 400 kilometers away from Earth, the Chinese space station has traveled into the sky, becoming one of the important milestones in China's aerospace industry. Looking at the northeast corner of China, a space environment ground simulation device called the "Ground Space Station" was officially completed recently and has entered the trial operation stage, with many indicators reaching world leading levels. As the first large scientific device in China's space field, the "Ground Space Station" is the first comprehensive research device with the most comprehensive environmental factors in the world, which can achieve multi-scale and cross scale environmental effects research. It will contribute wisdom and strength to the development of China's space industry and human Space exploration. According to the design plan, the "ground space station" can simulate nine categories of space environmental factors, such as vacuum, high and low temperature, charged particles, electromagnetic radiation, space dust, plasma, weak magnetic field, neutral gas, Micro-g environment, and can explain the impact of space environment on materials, devices, systems, and life forms. Compared to moving experimental instruments and equipment into space, a "ground space station" can not only save costs and reduce safety hazards, but also set specific environmental factors based on scientific issues and engineering needs, without being limited by time and space for multiple repeated verifications, thus creating safer and more convenient experimental conditions and research methods.
