The methods of deriving FeO and TiO2 contents from the Clementine spacecraft data were discussed, and an approach was developed to derive the content from the measurements using the Moon Mineralogy Mapper (M3) instrument on Chandrayaan-1. The density of lunar bedrock was then modeled on the basis of the derived FeO and TiO2 abundances. The FeO and TiO2 abundances derived from the M3 data were compared with the previous results of the Clementine data and were in good agreement. The FeO abundance data also agreed well with the Lunar Prospector data, which were used as an independent source. The previous Clementine and newly M3 derived abundances were compared with the laboratory measured FeO and TiO2 contents in the Apollo and Luna returned samples. The Clementine derived FeO content was systematically 1%–2% lower than the laboratory measurements in all the returned samples. The M3 derived content agreed well with the returned Apollo samples and was within ±2.8% of the laboratory measurements. The Clementine derived TiO2 abundance was systematically 0.1%–4% higher than the laboratory measurements of the returned samples. The M3 derived TiO2 agreed well (±0.6%) with the laboratory measurements of the returned samples, except for samples with high TiO2 content. However, these results should be carefully interpreted because the error range requires verification. No error analysis was provided with the previous Clementine derived contents.

基于月球矿物学制图仪观测的月球地下矿物学与密度剖面建模

讨论了从 Clementine 航天器数据中推导出 FeO 和 TiO 2含量的方法,并开发了一种方法来从使用Chandrayaan-1 上的 Moon Mineralogy Mapper (M 3 ) 仪器的测量中推导出含量。然后根据推导出的 FeO 和 TiO 2丰度对月球基岩的密度进行建模。来自 M 3数据的 FeO 和 TiO 2丰度与之前的 Clementine 数据结果进行了比较,并且非常一致。FeO 丰度数据也与 Lunar Prospector 数据非常吻合,后者被用作独立来源。以前的 Clementine 和新的 M 3派生的丰度与实验室测量的阿波罗和月球返回样品中的FeO 和 TiO 2含量进行了比较。在所有返回的样品中,克莱门汀衍生的 FeO 含量系统地比实验室测量值低 1%–2%。M 3衍生含量与返回的阿波罗样品一致,在实验室测量值的 ±2.8% 内。Clementine 衍生的 TiO 2丰度系统地比返回样品的实验室测量值高 0.1%–4%。M 3衍生的 TiO 2与返回样品的实验室测量结果吻合良好 (±0.6%),除了具有高 TiO 2 的样品内容。但是,应仔细解释这些结果,因为误差范围需要验证。之前的 Clementine 派生内容没有提供错误分析。
