Abstract

The invention relates to a spark surface gas component simulation device and method. In order to solve technical problems that an existing ground simulation scheme has large simulation errors and cannot truly and accurately simulate the pressure environment of the surface of Mars, the invention provides a device and a method for simulating gas components on the surface of Mars. The gas componentson the surface of the Mars are considered to the maximum extent, an atmospheric state of the Mars can be simulated close to the actual atmospheric state, and technical support is provided for a real and accurate environment simulation test of a Mars detector on the ground.

Description

technical field [0001] The invention belongs to the technical field of spacecraft testing, and in particular relates to a device and method for simulating gas composition on the surface of Mars. Background technique [0002] The purpose of human exploration of Mars is not only to explore the mysteries of the universe, but also because Mars is a close neighbor of our earth, and its characteristics are very similar to the earth in many aspects. Some people believe that the present of Mars is the future of Earth. Therefore, the exploration and research on Mars is very important for understanding the environment of the earth we live in, especially the long-term evolution process of the earth. [0003] my country formally proposed the Mars exploration plan in 2016 and has already begun to implement it. During the Mars exploration process, the test and experiment work that simulates the atmospheric environment on the surface of Mars is particularly important. This work largely de...
