“…Lunar crater size-frequency distributions have been used widely to determine the geologic ages of lunar surface [15,16]. The thicknesses of lunar regolith or strata have been measured by the radar or microwave radiometer data [17][18][19][20][21]. Since the Apollo missions, some gravity anomalies, such as Mascon, were detected by the measurement of lunar gravity and magnetic field for studying its inner structure [22,23].…”

The objectives of lunar satellite remote sensing are to study lunar surface characteristics, inner structure, and its evolution history. The contents of TiO 2 and FeO are assessed from Clementine UV/VIS data for Sinus Iridum. The geologic stratigraphic units and crates are interpreted visually based on SELENE Terrain Camera (TC) images and the spatial resolution of which is up to 10 m. And the geologic ages of different stratigraphic units are calculated by the crater size-frequency distributions measurements. The gravity anomaly is generated from SELENE gravity model (SGM90d) to show its difference from Mare Imbrium. Furthermore, the thickness of lunar regolith is also derived from microwave radiometer data of Chang'e-1 satellite.Integrating these results, it shows that the Sinus Iridum is different from the Mare Imbrium in inner structure and surface sedimentation. And its history of subsidence, deposition, volcanism, and impact is described. It makes sense to the future soft-landing and sampling at potential Sinus Iridum by remote sensing geologic analysis.Sinus Iridum, geologic remtoe sensing, investigation and mapping, Clementine, SELENE, Chang'e-1 PACS: 95.55.Pe, 96.20.Dt, 96.20.Br

“…However, with inadequate experience of thermal control and monitoring the MRM subsystem, validation and calibration of the MRM parameters were performed with CE-1's orbiting data by comparing the data with the Apollo landing site data. In a special issue of Chinese Sciences-D with a title of "Microwave Moon", six papers discussed the calibration and analysis of the MRM data [11,34,35].…”

The first Chinese lunar orbiter Chang'E-1 is a successful mission with many fruitful results obtained in various disciplines. The scientific data acquired by the Chang'E-1 payloads can benefit studies of the lunar origin and evolution, as well as other relevant research areas, after careful validation of the data. Among the new results, the Chang'E-1 selenodetic products are continually uncovering characteristics of the lunar surface, undersurface and inner structure. Successful lunar orbiters such as the Clementine, Lunar Prospector, KAGUYA/SELENE, Chang'E-1, Lunar Reconnaissance Orbiter and GRAIL have been revealing, with increasing clarity, global selenodetic characteristics with state-of-the-art fine resolution and high precision. In particular, the Chang'E-1 plays an important distinctive role in selenodetic exploration through enhancing lunar topography and gravity models. The gravity model has been successfully improved with a factor of two after applying the Chang'E-1 long-wavelength tracking data. Using the new models, some medium-scale lunar surface characteristics such as basins and volcanoes have been identified. Furthermore, the old mascon basins of Bouguer, gravity anomaly and craters have been discovered with the Chang'E-1 selenodetic data.Chang'E-1, lunar orbiter, lunar science, selenodesy, topography, gravity PACS: 91.10.Fc, 95.40.+s, 96.12.Bc, 96.12.Qr, 95.10.Eg, 95.75.De

“…The brightness temperature of the lunar regolith layer in the passive microwave remote sensing is numerically simulated by a three-layer model (the layering dust, regolith, and underlying rock media) using fluctuation dissipation theorem [9]. Based on the study by Shkuratov [10], Jin [11], Meng [12] and Wang [13], the complete lunar regolith model should consider the temperature profile, dielectric constant distribution, effective surface reflectivity.…”

During a few recent lunar missions, a possibility of water ice existing in the permanently shadowed regions on the moon has come forward. The content of water ice on the moon is an open question in the current I. MotivationMoon is the only natural satellite of the earth. Interest in moon increased as a result of various successful missions to the Moon like Selene (Japan), Chang'e-1 and Chang'e-2 (China), LRO (USA), Chandrayaan-1(India). Detection of presence of water ice within the planetary regolith is crucial for future manned explorations as well as for understanding geological history of the surface. Moon is known for having either no atmosphere or very light atmosphere, where no water can survive in its free form. The possibility of water/ice on the Moon could be due to bombardment of comets on lunar surface. The water molecules could be trapped inside the permanently dark regions near the pole. Thus, water can be present in the form of ice or mixed with lunar soil (regolith). Water ice content may be determined on the basis of theoretical modeling or using various detections methods sensitive to the water ice. This is the motivating factor for us to revisit the retrieval of water ice content on the moon using theoretical modeling. II. IntroductionThere has been a controversy on the presence of water ice on the Moon. Arnold was the first to suggest possible sources of the water ice near the lunar poles [1]. Watson and Arnold found that the most of the lunar polar regions are in the permanent shadow and the temperature at those locations is sufficiently low for the water to be preserved in the form of ice [2]. Clementine orbiter showed that the water might be present from the radar based experiment [3], but a later on Spudis [4] showed on the basis of earth based Arecibo observatory that water might not be present. Lunar Prospector (LP) neutron data, γ spectrometer data and radar data [5] found that water is present in the form of ice at lunar poles but a reanalysis by Nozettel and Hodges found that it was not but they found that Hydrogen is present based on theoretical modeling [3], [6]. The LRO mission then verified the existence of water ice on the moon [5], [6]. Using Clementine UVVIS data and improved Dobson model, Meng [7] evaluated water ice content near the poles and found water ice content to be 1.73 %. Meng, Chen and his colleagues [8] used Odelevsky dielectric mixing model and Chang'e-1 data to obtain water ice content in the Cabeus crater near the south pole and they found it to be 2.83 %.To obtain water ice content, microwave radiometer data are feasible as the previous researches [8] indicate. Therefore, in this paper, the passive microwave data from microwave radiometer onboard Chang'e-1 satellite are used and microwave radiative transfer equation is used based on the regolith model. The regolith in Cabeus crater could be the mixture of regolith and the water ice. The dielectric mixing models are compared to establish the relationship between the volume water ice content and the eff...
