Since the Moon's spin axis is tilted less than 2 degrees relative to its orbital plane, the interiors of many topographic lows (mostly impact craters) never receive any direct sunlight consequence is the presence of water ice on lunar poles. Lunar Reconnaissance Orbiter (LRO) mission revealed many facts about lunar surface in every manner. The Mini-RF experiment mapped the poles with radar. Results show that some craters near the pole contain material with high RF backscatter, known as high ratios of circular polarization (CPR). These anomalous craters with permanently dark floors show high CPR in their interiors but low CPR outside the crater rim. Additionally, the LOLA mapped the lunar surface with shadowed and non shadowed region.
Hermite (86N, 89.9E) is a worn, eroded crater with a rugged outer rim that is serrated and incised from past impacts. Its wide interior floor has been resurfaced and spotted with numerous tiny craterlets and low hills. Some of the portions are permanently shadowed regions including the coldest place in the solar system with a temperature of -249 degrees Celsius. This cold temperature is due to the fact that regions within this crater, which is located near the Moon's North Pole, never see sunlight.
High CPR within the range 1-2.5 has been observed over the crater. These results are consistent with the presence of relatively pure water ice or presence of the rock deposits (roughness). The Scattering decomposition shows that floor of crater having the secondary and chain of the crater but still some portion of this floor is smooth such portion is showing the surface scattering. Hermite crater is having a demolished rim outline with several superimposed post-impact secondary craters which modified and distorted its original shape and the rim. Due to impacting factors this crater has maximum portion covered by the volume scattering that includes distorted rim of crater and its secondary craters. Double bounce phenomena occur between two surfaces at an angle to one another due to presence of bedrocks beneath the surface. The three profiles of the crater have been established using LOLA which includes slope, roughness and height. For the presence of the water ice the physical parameters like slope, roughness, height and CPR should be taken care because these parameters affect the most. In this paper the amalgamation of microwave and optical data is done to detect the presence of the water ice on the shadowed region of hermite crater and also to identify its topography. The future work will corresponds to the confirmation of water ice over the detected area (results of this paper) using different techniques.
