摘要
This article reviews Mars sampling and return technology, by retrieving and analyzing the patents of domestic and foreign sampling equipment and mechanism technology, Mars surface removal technology and ultra-highspeed light and small sample return technology. It conducts patent analysis from the macro-technical view down to the micro-specific content view using statistical, quantitative and qualitative analysis methods. In the process of macro-analysis, it analyzes patent data from multiple perspectives such as time, region, technical composition, and applicants, and establishes the development trends for Mars sampling and return technology at home and abroad. In the process of micro-analysis, through the analysis and interpretation of key patents, we can learn the development priorities and development direction of foreign Mars sampling and return technology. This paper also proposes China’s Mars sampling and return technology development suggestions.
