چکیده انگلیسی
The porosity of the upper centimeter or so of the lunar regolith strongly affects several properties that are commonly studied remotely. Hence, it is important to determine its value. We have reanalyzed the data of Ohtake et al. (Ohtake et al. [2010]. Space Sci. Rev., 154, 57-77), who used spacecraft and laboratory reflectance measurements of the Moon by Kaguya Multiband Imager instruments and an Apollo sample to infer a lunar regolith porosity of 74-87%. Our analysis was augmented by using Lunar Reconnaissance Orbiter Wide and Narrow Angle Camera images. We confirm the Ohtake et al. (Ohtake et al. [2010]. Space Sci. Rev., 154, 57-77) estimate and refine it to 83 ± 3%. However, depending on the validity of key assumptions, this value could be a lower limit, so that the actual porosity could be somewhat higher. Even though the magnetic resonance index of the sample indicates that it is mature, it is appears to be optically less mature than a standard photometric site near the sample collection site.
