本文提出了一个新的概念，人类使命月球L2（拉格朗日）点，这将是一个试验场未来的深空探测任务，同时也监督科学上重要的调查。在月球背面的L2光环轨道上，猎户座载人飞船上的宇航员将比阿波罗宇航员离地球远15%，在深空停留的时间几乎是阿波罗宇航员的三倍。这样的使命将作为超越低地球轨道的第一步，并在更困难的人类探索任务之前证明太空飞行的操作能力，如生命支持，通信，高速重返和辐射防护。在这项拟议的使命中，宇航员将在未经探索的月球背面遥控着陆器/漫游车，从地质上有趣的背面获取样本，并部署一个低射频望远镜。南极-艾特肯盆地是太阳系中最古老的撞击盆地之一，对该盆地进行采样是2011年行星科学十年期巡天的一个关键科学目标。2010年天文学和天体物理学十年期巡天的一个优先事项是在低无线电频率下进行观测，以跟踪宇宙中第一批恒星/星系对星系间介质的影响。这种远程机器人监督还将展示人类和机器人在未来更复杂的深空任务（如探索火星）中的合作能力。(C)2012年空间研委会。由爱思唯尔有限公司出版。保留所有权利。
A novel concept is presented in this paper for a human mission to the lunar L2 (Lagrange) point that would be a proving ground for future exploration missions to deep space while also overseeing scientifically important investigations. In an L2 halo orbit above the lunar farside, the astronauts aboard the Orion Crew Vehicle would travel 15% farther from Earth than did the Apollo astronauts and spend almost three times longer in deep space. Such a mission would serve as a first step beyond low Earth orbit and prove out operational spaceflight capabilities such as life support, communication, high speed re-entry, and radiation protection prior to more difficult human exploration missions. On this proposed mission, the crew would teleoperate landers/rovers on the unexplored lunar farside, which would obtain samples from the geologically interesting farside and deploy a low radio frequency telescope. Sampling the South Pole-Aitken basin, one of the oldest impact basins in the solar system, is a key science objective of the 2011 Planetary Science Decadal Survey. Observations at low radio frequencies to track the effects of the Universe's first stars/galaxies on the intergalactic medium are a priority of the 2010 Astronomy and Astrophysics Decadal Survey. Such telerobotic oversight would also demonstrate capability for human and robotic cooperation on future, more complex deep space missions such as exploring Mars. (C) 2012 COSPAR.
