The Schrdinger basin on the south polar lunar far side has been highlighted as a promising target for future exploration. This report provides a high-resolution geologic map in the southwest peak-ring (SWPR) area of the Schrdinger basin, emphasizing structural features and detailed mapping of exposed outcrops within the peak ring. Outcrops are correlated with mineralogical data from the Moon Mineralogical Mapper instrument. Geologic mapping reveals a complex structural history within the basin through a system of radially oriented faults. Further, the geologic map shows both faulted and magmatic contacts between peak-ring mineralogies, providing both structural and magmatic context for understanding lunar crustal evolution and polar region processes. To investigate these relationships and address key scientific concepts and goals from the National Research Council (NRC) report, we propose three traverse paths for a robotic sample return mission in the SWPR area. These traverses focus on addressing the highest priority science concepts and goals by investigating known outcrops with diverse mineralogical associations and visible contacts among them. Coinciding with the preparation for the 2024 Artemis III mission, NASA is increasing the priority of robotic exploration at the lunar south pole before the next crewed mission to the Moon. Through mapping the Schrdinger SWPR, we identified the extent of different lunar crustal mineralogies, inferred their geologic relationships and distribution, and pinpointed traversable routes to sample spectrally diverse outcrops and outcrop-derived boulders. The SWPR region is therefore a promising potential target for future exploration, capable of addressing multiple high-priority lunar science goals.

使用新的地质图和漫游者遍历在月球远端的 Schrdinger 盆地进行人工样本返回任务

月球南极背面的薛定谔盆地已被强调为未来勘探的有希望的目标。本报告提供了薛定谔盆地西南峰环 (SWPR) 地区的高分辨率地质图,强调了峰环内裸露露头的构造特征和详细绘图。露头与来自月球矿物学测绘仪的矿物学数据相关联。地质填图通过径向断层系统揭示了盆地内复杂的构造历史。此外,地质图显示了峰环矿物学之间的断层和岩浆接触,为了解月球地壳演化和极地过程提供了结构和岩浆背景。为了调查这些关系并解决国家研究委员会 (NRC) 报告中的关键科学概念和目标,我们为 SWPR 地区的机器人样本返回任务提出了三个遍历路径。这些遍历侧重于通过调查具有不同矿物学关联和​​可见接触的已知露头来解决最高优先级的科学概念和目标。恰逢 2024 年阿尔忒弥斯三号任务的准备工作,美国宇航局正在提高在下一次载人登月任务之前在月球南极进行机器人探索的优先级。通过绘制 Schrdinger SWPR,我们确定了不同月球地壳矿物学的范围,推断了它们的地质关系和分布,并确定了可遍历的路线,以对光谱不同的露头和露头衍生的巨石进行采样。
