这是迄今为止最全面的月球地质图

  Cartographers merged Apollo-era maps and modern lunar observations to make the new graphic

  制图者将阿波罗时代的地图和现代的月球观测结果融合在一起,形成了这幅新的地图

  A new map of the moon is the most comprehensive geologic map of the lunar surface(nearside shown left,farside shown right).Different colors designate different surface features,such as lunar highlands(dark earth tones)and ancient lava flows(reds and purples).

  新的月球地图是最全面的月球表面地质图(左图近侧,右图远侧)。不同的颜色表示不同的表面特征,如月球高地(暗土色调)和古老的熔岩流(红色和紫色)。

  In the most comprehensive lunar map yet,the moon looks like it’s been playing paintball.

  在迄今为止最全面的月球地图上,月球看起来就像在玩彩弹游戏。

  每一种飞溅的颜色都代表一个独立的岩石或沉积物的形成

  Each splash of color identifies a discrete rock or sediment formation,including craters,basins and ancient lava fields.For instance,“the darker,more earth tones are these highland-type terrains,and the reds and the purples tend to be more of these volcanic and lava flow materials,”says geologist James Skinner,who oversees the production of standardized maps for solar system bodies at the U.S.Geological Survey in Flagstaff,Ariz.(For more details on exactly what those colors mean,check out the map in all its glory here.)

  每一种飞溅的颜色都代表一个独立的岩石或沉积物的形成,包括陨石坑、盆地和古代熔岩场。例如,“这些高地类型的地形是深色和更多的土黄色,而火山岩和熔岩流中的物质更多是红色和紫色”。地质学家James Skinner负责为亚利桑那州弗拉格斯塔夫的美国地质调查局监督太阳系天体的标准地图制作。

  The Unified Geologic Map of the Moon,released April 20 by the USGS,as it’s called,combines information from six regional lunar maps created during the Apollo era,as well as recent spacecraft observations.The modern data include views of the north and south lunar poles made by NASA’s Lunar Reconnaissance Orbiter,and observations around the equator from the Japanese Aerospace Exploration Agency’s SELENE lunar orbiter(SN:7/10/19).

  美国地质调查局(USGS)于4月20日公布了这张月球地质图,它综合了阿波罗(Apollo)时代绘制的六幅月球的区域地图信息,以及最近的宇宙飞船观测数据。现代数据包括美国国家航空航天局(NASA)的月球勘测轨道飞行器拍摄的月球南北两极的照片,以及日本航空航天局的塞莱纳(SELENE)月球轨道飞行器(SN7/10/19).

  This lunar cartography project was trickier than just fitting Apollo-era maps together like puzzle pieces and using new data to tweak the details—in part,because the edges of the regional maps didn’t line up.Many surface features at the boundaries between neighboring maps were labeled with inconsistent names,descriptions and ages.

  这个月球制图项目比仅仅把阿波罗时代的地图像拼图一样拼在一起并使用新的数据来调整细节要复杂得多,部分原因是区域地图的边缘没有对齐。许多相邻地图边界处的地物被标记上不一致的名称、描述和年代。

  阿波罗时代的地图是由不同的研究小组绘制的

  Those discrepancies arose because the Apollo-era maps were created by separate research groups,and two different teams looking at the same parts of the moon could interpret what they saw differently.For instance,one group might have seen something jagged on the surface and called it a fault,whereas another team could have read it as a fragment ejected during the formation of a crater.

  这些差异产生的原因是,阿波罗时代的地图是由不同的研究小组绘制的,而两个研究月球相同区域的不同团队可以对他们看到的情况做出不同的解释。例如,一个小组可能看到表面有锯齿状的东西,并称之为断层,而另一个小组可能会将其解读为陨石坑形成过程中喷出的碎片。

  Skinner and colleagues reconciled those discrepancies by analyzing information from all six regional maps,along with the new lunar orbiter observations,to figure out the proper identifications for different surface features.That allowed the team to draw up a comprehensive geologic map of the whole moon.

  斯金纳和他的同事们通过分析所有六幅区域地图的信息,以及最新的月球轨道飞行器观测数据,调和了这些差异,以找出不同表面特征的正确识别方法。这使得研究小组能够绘制出一幅完整的月球地质图。

  Detailed observations from the lunar orbiters were especially helpful for clearing up uncertainties in how different craters overlapped with each other,which revealed the craters’relative ages.Hammering out crater formation timelines gives insight into the moon’s history(SN:3/26/18).

  来自月球轨道器的详细观测尤其有助于消除关于不同陨石坑如何相互重叠的不确定性,从而揭示出陨石坑的相对年龄。计算出陨石坑形成的时间线使人们得以更加深入的了解月球的历史(SN:3/26/18).

  The new map could also inform future human missions to the moon by revealing regions that may be rich in useful resources or areas that need more detailed mapping to land a spacecraft there safely(SN:12/16/19).

  新的地图还可以显示可能富含有用资源的地区,或者还需要更详细描绘的地区(以使航天器安全着陆),并为未来的人类登月提供任务(SN:12/16/19).
