Introduction
摘要
The Russian scientist Konstantin Tsiolkovsky (1857–1935) predicted that “Mankind will not always stay on the Earth; the pursuit of light and space will lead him to penetrate the bounds of the atmosphere, timidly at first, but in the end to conquer the whole of solar space”. Since the successful launch of the first satellite, Sputnik-1, in 1957, humanity has achieved remarkable milestones in artificial satellite missions and human spaceflight.
