我团队构建嫦娥六号着陆区高精度地形数据集

Group 1 - The research team led by Li Chunlai from the National Astronomical Observatories of the Chinese Academy of Sciences successfully constructed a high-precision terrain dataset of the Chang'e 6 landing area using high-resolution images captured by the spacecraft [1] - The study published in Nature Communications provides detailed geological information about the landing site, including soil roughness, crater shapes, regolith thickness, and rock abundance, which are crucial for subsequent laboratory studies of lunar samples [1][2] - The Chang'e 6 landing point is located on the southwestern edge of a crater with a diameter of approximately 51 meters, indicating that the area is part of the basalt region of the lunar mare [1] Group 2 - The landing area is characterized by numerous impact ejecta patterns, with the soil composition identified as a "mixed formula" consisting of approximately 30%-35% local basalt from the nearby C1 crater and 5-16 centimeters of foreign material possibly sourced from more distant craters [2] - This research provides critical scientific evidence regarding the material sources of the Chang'e 6 lunar samples, laying the groundwork for future laboratory research and detailed analysis of lunar samples [2]
