中国首次开展的探月工程再入返回试验日前取得圆满成功,而大约在同一时间点上,美国“天鹅座”货运飞船、英国商业载人飞船“太空船”二号接连发生坠毁事故。一方面,欧美等国对太空探索的勇敢尝试昭示中国必须加快稳步前进的步伐:另一方面,航天型号的高风险、高投入的特点,决定了政府资金和政策等的有力扶持会为航天事业发展提供更为可靠的安全保障。20世纪中期以来一些国家向月球和更遥远的天体发射了大量探测器和飞船,但按设计要求返回地球的航天器为数寥寥。除了项目内容本不包括“回家”任务以外,再入返回技术复杂和风险 The first successful launch of the lunar exploration project in China was a complete success before the return test. At about the same time, the U.S. Cygnus cargo ship, the British commercial manned spacecraft, and the spacecraft II crashed one after another ACCIDENT. On the one hand, courageous attempts by European and American countries to explore space have shown that China must step up its pace of steady progress. On the other hand, the high-risk and high-input nature of the space model determines the strong support of government funds and policies that will provide spaceflight Development to provide more reliable security. Some countries have launched large numbers of spacecraft and spacecraft on the moon and beyond in the mid-20th century, but only a few spacecraft are required to return to Earth upon design. In addition to the contents of this project does not include the “home ” task, re-entry technology complex and risk
