Abstract: As the sister planet of the Earth, Venus has an appreciable scientific exploration value. Due to the complexity of the environment of Venus, the feasible way to understand the interior of Venus is through the landing and close-up detection. The simulation of the atmosphere of Venus is the key to the successful development of Venus landing and floating probe in the future. This paper firstly combs out the key technologies for Venus near-space environmental simulation, including the accurate measurement and control of trace gases, the temperature and pressure control and measurement of gases under high temperature and high pressure; then reviews the domestic and foreign Venus atmospheric environmental simulation system tests. Based on the analysis of the specific requirements of the environmental simulation for Venus exploration missions, some suggestions are put forward for China to ensure the successful simulation test under the simulated Venus surface environment.
