美国宇航局马歇尔太空飞行中心（MSFC）与美国地质调查局（USGS）合作，正在实施一项新的数据采集战略，以支持月球风化模拟物的开发和评估。目的是表征月球风化层的颗粒组成、大小、形状和体积密度的变化。阿波罗号的驱动岩芯和钻取岩芯是首选的样本，因为它们可以研究月球深度的变化，而且许多拟议的月球行动将涉及挖掘至少数十厘米深的月球风化层。多个阿波罗核心将沿着其垂直轴进行多次采样并进行分析。这将允许对核心内部、紧密间隔的核心之间以及遥远区域之间的变化进行统计陈述。
NASA's Marshall Space Flight Center (MSFC), in conjunction with the United States Geological Survey (USGS), is implementing a new data acquisition strategy to support the development and evaluation of lunar regolith simulants. The objective is to characterize the variance in particle composition, size, shape, and bulk density of the lunar regolith. Apollo drive and drill cores are the preferred samples as they allow for investigation of variation with depth, and many proposed operations on the moon will involve excavation of lunar regolith to depths of at least tens of centimeters. Multiple Apollo cores will be sampled multiple times along their vertical axes and analyzed. This will permit statistical statements about variation both within a core, between closely spaced cores, and between distant areas.
