选择中国载人航天发展目标的讨论

回顾人类载人航天40余年的历程，出现过一些弯路，究其原因是多方面的，但主要的是如何合理选择各自的发展目标，发展载人航天的目标大致可有6项，开发利用空间微重力环境物质资源，开发利用空间轨道能源资源，开发利用月球能源资源，发展天基航天利用空间位置资源，在月球上扩大人类生存空间，在火星上扩大人类生存空间，文章系统分析了国际上现有载人航天工程的经验和教训，认为结合中国的具体实际，中国载人航天发展的目标应重点考虑开发利用空间微策略环境物质资源和发展天基航天。

A Discussion on the Development Goal of Manned Space Flight in China

Reviewing the forty years history of manned space flight, people may find some round about courses for many reasons, among which the main one is how to choose the development goal reasonably.To develop manned space flight has six goals: development of resources of microgravity environment in space, development of resources of space orbit energy, development of resources of lunar energy, development of space based space flight and usage of resources of space positions, expanding living space of human beings on moon, expanding living space of human beings on Mars. This paper analyzes the experience and lessons of current international manned space flight. In view of China's situation, this paper believes that the goal of China's manned space flight should be the development and usage of resources of microgravity environment or space based space flight.
