载人登月工程是美国国家航空和航天局在二十世纪六七十年代组织实施的载人登月工程,或称“阿波罗 计划”。阿波罗计划采用月球轨道交会法,用强大的土星五型运载火箭把50吨重的航天器送入月球轨道。航天器入月球轨道。航天器本身装有较小的火箭发动机, 当它接近月球时,能使航天器减速进入绕月轨道。而且,航天器的一部分——装有火箭发动机的登月舱能脱离航天器,载着宇航员登上月球,并返回绕月轨道与阿波 罗航天器结合。工程开始于1961年5月,至1972年12月第6次登月成功结束,历时约11年,耗资255亿美元。在工程高峰时期,参加工程的有2万家 企业、200多所大学和80多个科研机构,总人数超过30万人。(Quelle:http://news.xinhuanet.com/)
