项目摘要

Landing a seismometer on Mars will answer one the most important unknown questions about the Martian environment, is Mars still geologically active? We can see evidence for ancient geological activity on Mars in many forms (e.g. the giant volcanoes such as Olympus Mons), but the current level of Martian geological activity is a mystery. On the Earth and Moon (and also the Sun) seismic studies have been used to probe both deep and local internal structure / our models of the Earth with a deep molten core, mantle and crust are based on modelling the propagation of seismic events (e.g. Earth quakes) through the Earth. A seismic station on Mars will give us a glimpse into the interior of another terrestrial planet for the first time ever. A seismic study of Mars has been one of the highest priorities for Martian exploration for at least the last ten years. The silicon microseismometer described in this proposal represents a unique opportunity for the UK to participate in the geophysical science of ExoMars within Aurora. The microseismometer is a critical sensor for in-situ Mars exploration and will provide data on the key questions of Martian seismicity and internal structure. If, as expected, a significant number of natural sources on Mars produce large events the instrument will be able to provide information on: 1, Source distance 2, An estimate of the source direction. 3, An approximate value for the depth of the source. These measurements will reveal the level and type of internal activity on present-day Mars. For example, are there deep events of any kind within Mars, and if so, do they tell us anything about large-scale mantle convection? Once the approximate source location has been determined, the data can then be used to study the Mars' internal structure, specifically: 1, Measure the depth to the core/mantle boundary. 2, Measure the thickness of the crust 3, Look for small and large scale sub-surface structure. As well as probing the deep structure of Mars, the microseismometer will be used to investigate local structure using small local sources such as dust-devils, dust-storms and even the motion and activity of the ExoMars rover itself and will provide a geological context for the ExoMars science results. The microseismometer will have important applications for use on other missions (e.g. future seismic stations on Mars or the Moon) as well as on the Earth. The sensor and electronics are being designed to work at extreme temperatures (150K (-123C)) and for extended periods of time (2 Martian years, approximately 4 Earth years). This results in a robust design ideal for adaptation to harsh environments on the Earth, such as ocean bottom seismic networks or volcanic monitoring.

在火星上登陆地震仪将回答一个关于火星环境的最重要的未知问题，火星仍然在地质上活跃吗？我们可以看到以多种形式对火星的古老地质活动的证据（例如，奥林巴斯·蒙斯（Olympus Mons）等巨型火山），但目前的火星地质活动水平是一个谜。在地球和月球（以及太阳）上的地震研究已被用来探测深层和局部内部结构 /我们的地球模型，具有深层熔融的核心，地幔和地壳是基于建模地震事件（例如地球地震）通过地球的传播建模。火星上的地震站将使我们首次瞥见另一个陆地星球的内部。至少在过去十年中，对火星的地震研究一直是火星勘探的最高优先事项之一。该提案中描述的硅微量震仪为英国参与Aurora内的外事物科学科学的独特机会。微量抗压仪是现场火星探索的关键传感器，将提供有关火星地震性和内部结构的关键问题的数据。如果正如预期的那样，火星上有大量的自然来源产生了大型事件，则仪器将能够提供有关：1，源距离2（源方向估计）的信息。 3，源深度的近似值。这些测量结果将揭示当今火星上内部活动的水平和类型。例如，火星中是否有任何形式的深层事件，如果是这样，他们会告诉我们有关大规模对流的任何信息吗？一旦确定了近似源位置，就可以使用数据来研究火星的内部结构，特别是：1，测量深度到核心/地幔边界。 2，测量地壳3的厚度，寻找小大小的地下结构。除了探测火星的深层结构外，微量震荡计还将用于使用小局部来源（例如尘埃鬼，尘埃形式，甚至外显子。微量抗压器计将在其他任务（例如火星或月球上的未来地震站）以及地球上使用重要的应用。传感器和电子设备的设计用于在极端温度（150K（-123C））和长时间（2火星年，大约4个地球年）中工作。这为适应地球上恶劣环境（例如海洋底部地震网络或火山监测）提供了理想的设计。
