Ancient bombardment of the inner solar system - Reinvestigation of the "fingerprints" of different impactor populations (A03+)

检查月球陨石坑大小和频率分布的形状将有助于确定太阳系内射弹的来源区域，并提高我们对潜在的时变陨石坑生产函数的理解。为实现这些目标，该分项目包括详细的地质测绘、高分辨率火山口大小和频率测量以及地理信息系统空间分析新方法的应用。这些工具用于研究随后修改原始陨石坑分布的过程，并验证先前用于分析陨石坑大小和频率分布的区域的适用性。

Examining the shapes of lunar crater size¿frequency distributions will help identify the source regions of the projectiles within the solar system and improve our understanding of a potential time-variable crater production function. To achieve these objectives, this subproject includes detailed geologic mapping, high-resolution crater size¿frequency measurements, and the application of new approaches of GIS spatial analyses. These tools are used to investigate the processes subsequently modifying the original crater distributions and to validate the suitability of the regions previously used to analyze crater size¿frequency distributions.
