Zebker, HowardStanford UniversityAST 99-72886Drs. Zebker and Tyler will use radar observations to study the structure in the icy surfaces of the Galilean satellites of Jupiter. Improvements to both Arecibo and the NASA Goldstone Solar System Radar will provide higher resolution images than previously available and allow improved constraints on the subsurface structure within the crust. Modeling of coherent backscatter will permit the determination of the spatial and depth distributions of cracks, bubbles, and inclusions within the lithosphere and constrain models of the surface evolution of the moons.

Zebker，HowardStanford UniversityAST 99- 72886博士泽布克和泰勒将利用雷达观测来研究木星伽利略卫星冰表面的结构。 对阿雷西博和美国航天局戈德斯通太阳系雷达的改进将提供比以前更高分辨率的图像，并改善对地壳内地下结构的限制。 相干后向散射的建模将允许确定岩石圈内的裂缝，气泡和夹杂物的空间和深度分布，并约束月球表面演化的模型。
