A new map of the Moon has revealed an abundance of titanium ore that is up to 10 times richer than on Earth, a finding that could one day lead to a lunar mining colony, astronomers said on Friday. 天文学家在周五称，一张新的月球地图展示出了在月球上发现了高于地球10倍储备量的钛矿，这个发现有可能会引发一场未来月球采矿业的殖民行为。 The discovery was made thanks to a camera aboard the US Lunar Reconnaissance Orbiter, which swept the surface of the Moon, scrutinising it in seven different light wavelengths. 这个发现要归功于美国月球轨道勘测器上的一个摄像头。 该探测器利用七种不同光的波长对月球表面进行勘察。 Mark Robinson of Arizona State University, sifted through the data for telltale jumps in the ratio of ultra-violet to visible light. 亚利桑那州立大学的马克-罗宾逊，筛选了由紫外线和可见光的比率所得到的数据而得出这一结论（月球上存有钛矿）。 They established this signature thanks to rock samples brought back to Earth by Apollo 17 astronauts in 1972 and images of the area around the mission's landing site by the Hubble space telescope. 而他们能确定钛矿的位置标记却要归功于在1972年阿波罗17号宇航员带回地球的岩石样本和通过哈伯望远镜观测到的围绕任务着陆点的地区图像。 |
