项目摘要

The four-year orbital mission of NASA's MESSENGER spacecraft will end in March 2015. In preparation for Europe's Mercury orbiter (BepiColombo), which will be launched in 2016, a co-ordinated effort is being mounted by the MESSENGER and BepiColombo teams to produce geological maps of the whole of Mercury using the best MESSENGER data available. The maps will provide very important contextual information for planning and interpreting BepiColombo data, and will replace the partial map coverage at 1:5M scale achieved using Mariner-10 data.Mercury is divided into 15 mapping 'quadrangles' (including one at each pole), and the student on this project will be responsible for creating a geological map of one of these under the guidance of the supervision team. The allocation of quadrangles between groups is being negotiated and should become clear by early summer. However, every quadrangle has a wide range of features and a long and complex geological history making it an exciting region to study.The student will compile a geological map in ArcGIS using MESSENGER narrow- and wide-angle-camera images supplemented by topographic, spectral and geochemical data, all of which will be available from NASA's Planetary Data System (pds.nasa.gov), and will co-ordinate with colleagues mapping adjacent quadrangles. Mapping will follow United States Geological Survey protocols and conventions agreed among the joint MESSENGER-BepiColombo geological mapping team, and the map will be published via USGS. Online digital publication facilitates the inclusion of multiple layers, so that (for example) this new generation of maps could have a chronostratigraphic version (surface units divided by age, such as smooth plains, intercrater plains, and so on) and a more innovative lithostratigraphic version (for example subdividing plains into spectral/geochemical types). Mercury is tectonically complex, and so the systems of isolated and linked faults will require careful attention.Although a thorough quadrangle map will be the main product of this study, the intimate insight gained by close examination of any part of Mercury will offer plenty of opportunities for spin-off science. These could, for example, be geochemical, geomorphological, tectonic, related to space-weathering, or related to volatile processes, according to the student's interests. We would expect the student to present findings at meetings such as the annual Lunar & Planetary Science Conference (Houston) and the European Planetary Science Conference, and also to submit papers for publication in peer-reviewed journals.The supervisors will train the student in ArcGIS and planetary geological mapping, in addition to which there will be opportunities to attend MESSENGER-BepiColombo mapping workshops in Europe and/or the USA. Experience of geological mapping in Earth would be an advantage.

美国宇航局信使号航天器为期四年的轨道任务将于2015年3月结束。为了准备将于2016年发射的欧洲水星轨道器(比皮科伦坡)，信使号和比皮科伦坡团队正在开展一项联合工作，利用现有的最佳信使数据绘制整个水星的地质图。这些地图将为规划和解释比佩科伦坡数据提供非常重要的背景信息，并将取代使用Mariner-10数据实现的1：5米的部分地图覆盖。水星被划分为15个测绘‘四边形’(包括每一极一个)，该项目的学生将在监督小组的指导下负责创建其中一个的地质图。各团体之间四合院的分配问题正在谈判中，应该会在初夏时明朗化。然而，每个四合院都有广泛的特征和漫长而复杂的地质历史，这使得它成为一个令人兴奋的研究区域。学生将使用Messenger窄角和广角相机图像，辅以地形、光谱和地球化学数据，在ArcGIS中编制地质图，所有这些数据都将从NASA的行星数据系统(pds.nasa.gov)获得，并将与同事协调绘制相邻四合院的地图。测绘将遵循信使-比佩科伦坡联合地质测绘小组商定的美国地质调查局议定书和公约，地图将通过美国地质勘探局发布。在线数字出版促进了多层的纳入，因此(例如)这一新一代地图可以具有年代地层学版本(地表单位按年龄划分，如光滑平原、火山口间平原等)和更具创新性的岩石地层学版本(例如，将平原细分为光谱/地球化学类型)。水星的构造很复杂，因此需要仔细关注孤立和相连的断层系统。尽管这项研究的主要成果将是一张全面的四边形地图，但通过仔细检查水星的任何部分获得的深入洞察将为衍生科学提供大量机会。例如，根据学生的兴趣，这些可能是地球化学、地貌、构造、与空间风化有关的或与挥发性过程有关的。我们期望学生在一年一度的月球和行星科学会议(休斯敦)和欧洲行星科学会议等会议上发表研究成果，并提交论文发表在同行评议的期刊上。导师将对学生进行ArcGIS和行星地质制图方面的培训，除此之外，还将有机会参加信使-贝普科伦坡在欧洲和/或美国的地图绘制研讨会。有地球地质测绘经验者优先。
