21世纪是空间探索和开发应用的世纪,以进入空间、利用空间、控制空间为特征的制天权的争夺成为未来战争的焦点,军事航天系统成为现代化战争制胜的关键。作为航天技术的基础,航天运输系统技术代表着一个国家自主进入空间的能力,可重复使用天地往返运输系统是未来航天运输系统的主要发展方向。确保快速、机动、廉价、可靠地进入空间,不仅是实现迅速部署、重构、扩充和维护航天体系的基础,而且也是降低空间进入门槛、大规模开发利用空间资源的基础和前景。
The 21st century is the century for space exploration and development and application. The battle for the celestial right featuring space and space and space control becomes the focus of future wars. The military space system has become the key to victory in modernized wars. As the basis of aerospace technology, the technology of space transportation system represents the ability of a country to enter the space autonomously. The reusable transportation system of the Earth and the Earth is the main development direction of the future space transportation system. Ensuring that rapid, mobile, affordable and reliable access to space is not only the basis for rapid deployment, reconstruction, expansion and maintenance of the space system, but also the basis and prospects for reducing the space entry threshold and for the large-scale development and utilization of space resources.
