LUNAR SURFACE ENVIRONMENTAL CHARACTERISTICS
|
Abstract:
Based on the exploration data and previous studies, the authors suggest that small volume and mass of the moon, the short distance from the sun ( i e . high surface temperature) result in the very tenuous and thin lunar atmosphere, demonstrate that there exits ice water on shadow area of the lunar polar region and calculate out 6.6 Ga tons of ice. By comparing the composition of rare gas elements in the lunar regolith and in the solar wind, the authors analyze the physical, chemical and isotopic effects of the solar radiation on the lunar surface materials, the distributions and contents of the 3He in the lunar regolith, point out that the content of 3He relates with grain size, the mineral components, structures and elemental compositions of the lunar soil, and evaluate the exploration values of 3He. The lunar surface materials govern the lunar reflectance. Based on the spectrum characteristics of the mare basalts, highland plagioclases and their mineral components which both of them are the main rocks of the lunar surface materials, the authors analyze the different reflectance of the lunar near side and far side. Not only is the lunar magnetic field the important part of the lunar environment but also great significance for studying on the lunar interior structures. The moon has regional scale distribution magnetic field which may result from great impact processes.$$$$
