Abstract
Chang'e21 Microwave Sounder (CELMS) is a main payload of Chang'e21 Moon Orbit Satellite in the first stage of China Lunar Probe. CELMS is a four frequency microwave radiometer wit h f requencies 3GHz ,7.8 GHz ,19.35 GHz and 37 GHz. During the one year and four months'working in lunar orbit,it got huge scientific data covering full moon surface was got and moon globe microwave emission feat ure world was obtained fir stly ,besides ,for the fir st time in the world ,the microwave bright ness temperature map in globe scale was achieved and the Microwave Moon (MicM) was established. MicM consist s of a moon globe microwave bright ness temperat ure map ,lunar pole microwave anomalies feature map and some featured area microwave emission feature maps.In this paper ,some new results from MicM analyzing was given ,especially t he new features of lunar far-side world first ,such as the microwave bright ness temperat ure of far2side is much lower t han t hat of near-side ,which may be concerned with geological feature of far-side and the evolution history of t he moon.The regolith layer thickness of far-side is much thinner than near side while the dielect ric constant of area 40°S-70°S and 150°W-150°E is fairly low ,which shows that the dielect ric constant of t his area is veryhigh.The CELMS result shows that the moon globe regolith depth is 5-6 meter s in average and 3He is closer to 1 million tone.
