Microwave thermal emission features of Mare Orientale revealed by CELMS data

摘要

As Mare Orientale is the youngest and best preserved multiring impact basin on the Moon, it is of essential importance to study its composition and structure for current Moon research. In this paper, the CELMS data from Chang'E-2 satellite are employed to reveal the microwave thermal emission features of the Mare Orientale. The results indicate that the regions with high TB and high TB difference are strongly influenced by FTA, but FTA is not the only factor. Moreover, the lunar regolith structure is not even at the mare basin. Furthermore, there exist abundant abnormal TB and high TB difference regions which could hardly be explained by the current Moon research.
