| Abstract: |
| Reusable spacecraft is characterized as a fast and cost efficient method for space access and return. Since the concept of reusable spacecraft was proposed in the 1950s, over 70 years have passed and significant progress has been made in the development of reusable spacecraft, accumulating rich experience and lessons. Based on the development worldwide, technical routes of reusable spacecraft are illustrated, and the developing trends are gained. Features and difficulties related to reusable spacecraft are discussed from four aspects including design, manufacture, test, operation and maintenance. Furthermore, several thoughts and suggestions on the future development of reusable spacecraft are provided. |
