Abstract: Firstly this paper introduces the development history and current situation of foreign aerospace vehicle technology. According to the world development experiences and the aerospace vehicle’s flight features, we raise the basic science problems of aerospace vehicle technology, and propose the solutions of aerospace vehicle technology based on current technological level. In conclusion, the development direction of aerospace vehicle technology is elucidated. It is generally known that the long term future of mankind must be in outer space. Developing a new generation of space transportation system is not only the requirement of large scale exploitation and utilization of outer space, but also will open up a new era of outer space. 

Key words: Aerospace vehicle, Space transportation system, Reusable vehicle, Space launch
