Estimate of Lunar TiO2 and FeO with M3 Data
Lunar Fe (iron) and Ti (titanium) are two important elements distributed on the Moon. In the current study, visible to near-infrared reflectance data acquired by the Moon Mineralogy Mapper (M3) on Chandrayaan-1 (Clark et al. 2010; Pieters et al. 2009; Dhingra et al. 2010) are used to investigate the FeO and TiO2 abundance of lunar surface at global scales.
The motivation for this study is to apply previous methods derived from the Clementine mission to a new dataset. The M3, a high-resolution, high-precision imaging spectrometer, flew on board India’s Chandrayaan-1 Mission from October 2008 through August 2009.
The M3 dataset is very large (3.63 terabytes), and the reduction of data from the PDS archive was complex. However, M3data’s high spatial resolution (70 m/pixel target mode, 140 m/pixel global mode) and spectral resolution (256 channels target mode, 85 channels global mode) indicate its huge potential advantage when compared with previous products derived from the...
