The Mars 2020 Perseverance rover landing site is located within Jezero crater, a $\sim50~\mbox{km}$ diameter impact crater interpreted to be a Noachian-aged lake basin inside the western edge of the Isidis impact structure. Jezero hosts remnants of a fluvial delta, inlet and outlet valleys, and infill deposits containing diverse carbonate, mafic, and hydrated minerals. Prior to the launch of the Mars 2020 mission, members of the Science Team collaborated to produce a photogeologic map of the Perseverance landing site in Jezero crater. Mapping was performed at a 1:5000 digital map scale using a 25 cm/pixel High Resolution Imaging Science Experiment (HiRISE) orthoimage mosaic base map and a 1 m/pixel HiRISE stereo digital terrain model. Mapped bedrock and surficial units were distinguished by differences in relative brightness, tone, topography, surface texture, and apparent roughness. Mapped bedrock units are generally consistent with those identified in previously published mapping efforts, but this study’s map includes the distribution of surficial deposits and sub-units of the Jezero delta at a higher level of detail than previous studies. This study considers four possible unit correlations to explain the relative age relationships of major units within the map area. Unit correlations include previously published interpretations as well as those that consider more complex interfingering relationships and alternative relative age relationships. The photogeologic map presented here is the foundation for scientific hypothesis development and strategic planning for Perseverance’s exploration of Jezero crater.

火星 2020 科学团队绘制的杰泽罗陨石坑毅力号火星车现场摄影地质图

火星 2020 毅力号火星车着陆点位于 Jezero 陨石坑内，这是一个直径 $\sim50~\mbox{km}$ 的撞击坑，被解释为 Isidis 撞击结构西缘内的诺亚时代湖盆。杰泽罗拥有河流三角洲的遗迹、入口谷和出口谷，以及含有多种碳酸盐、镁铁质和水合矿物的填充沉积物。在 2020 年火星任务启动之前，科学团队成员合作制作了杰泽罗陨石坑毅力号着陆点的摄影地质图。使用 25 cm/像素高分辨率成像科学实验 (HiRISE) 正射影像镶嵌底图和 1 m/像素 HiRISE 立体数字地形模型以 1:5000 数字地图比例进行制图。映射的基岩和地表单元通过相对亮度、色调、地形、表面纹理和表观粗糙度的差异来区分。绘制的基岩单元总体上与之前发布的测绘工作中确定的一致，但本研究的地图包括 Jezero 三角洲地表沉积物和亚单元的分布，比之前的研究更详细。本研究考虑了四种可能的单位相关性来解释地图区域内主要单位的相对年龄关系。单位相关性包括先前发表的解释以及考虑更复杂的相互关系和替代相对年龄关系的解释。这里展示的摄影地质图是毅力号探索杰泽罗陨石坑的科学假设发展和战略规划的基础。
