This paper briefly describes the process of international Mars exploration and analyzes the development of Chinese Mars exploration. It focuses on introducing the scientific significance and engineering difficulties of Mars exploration, and provides an overview of the system design of the probe, including the flight profile, the preliminary selection of the landing site, the entry, descent and landing （also known as EDL） process. Four types of key technologies, including telecommunications, autonomous control, the EDL process, and its structure and mechanism, are detailed in this paper. Finally, the paper highlights the expected scientific and engineering results of the mission.展开更多

The development of GLP in China started in the late 1990 s. Following 20 years of developments, GLP system has already been established in this country. This review firstly evaluated all the institutions in this field, and described the annual number and total number of institutions, the distribution of GLP institutions, the types of GLP institutions, and the service provided by these GLP institutions. Since the initiation of the National Key Technology R＆D Program during the 11 th Five-Year Plan, it had a significant effect on the development of GLP. Therefore, the institutions which have undertaken projects from this program will be introduced later. We also described the infrastructure of hardware and software in GLP institutions along with their faults, such as variation in development and the lack of innovation.展开更多
