中文百科

月球轨道交会

月球轨道交会Lunar Orbit Rendezvous)是阿波罗计划中使用的登月飞行方法,具体是一个主航天器携带一艘小型的航天器,并由子航天器登月。这是最初提出的3种登月办法中的一种。

第1种是直接起飞。顾名思义,一个巨大的火箭(起名为“新星”)直接起飞,独自携带所有登月所需航天器,前往月球。

第2种是地球轨道交会,两个小一些的火箭携带航天器以及燃料在地球轨道对接,然后前往月球。

第3种则是月球轨道交会,一个由约翰·C·霍博尔特的团队提出的方案。这种方案是一艘较大的航天器携带一艘装载宇航员的登月航天器,进入月球轨道之后,登月航天器与主航天器分离,并降落在月球表面;主航天器留在月球轨道。3名宇航员中的1名留在主航天器中。登月完成之后,登月航天器重新起飞,与主航天器在月球轨道集合,并返回地球。

Lunar orbit rendezvous (LOR) is a key concept for landing humans on the Moon and returning them to Earth and was first utilized for the Project Apollo missions in the 1960s and 1970s. In a LOR mission, a main spacecraft (such as the Apollo CSM) and a smaller lunar lander (such as the Apollo LM) travel together into lunar orbit. The lunar lander then independently descends to the surface of the Moon, while the main spacecraft remains in lunar orbit. After completion of the mission there, the lander returns to lunar orbit to rendezvous and re-dock with the main spacecraft, then is discarded after transfer of crew and payload. Only the main spacecraft returns to Earth.
