Detailed analysis of samples from planetary bodies is central to understanding the story of our Earth and the wider Solar System. A huge range of specialised instruments have been developed to this end, and many of them are now used in much more immediate ways - seeking for resources, understanding our civilization's effect on the environment, tracing the pathways chemicals move through our bodies, causing and curing diseases. In each case, the most progress is made when multiple different techniques are used to understand a single sample. In addition, it is vital to extract the maximum amount of useful information from each analysis to understand its implications properly.In Manchester we have a wide range of such specialised instrumentation, some of which is unique in the world because we have developed it ourselves. In this proposal, we seek to fund a technique that will complement our existing capabilities. This instrument uses a very short laser pulses to fragment spots in the surface of a sample that are smaller that a tenth of a millimetre. The fragments are carried by a gas flowing over the sample surface into a mass spectrometer that analyses the elements that were present. When the information from this technique is combined with the output from our other analytical techniques we will have a new and powerful way of studying the nature and sequence of processes that led from the condensation of the first dust in our solar system to the formation of planets like the Earth. We will also be able to understand how the surfaces of other planetary bodies, especially Mars and the Moon, formed and evolved through volcanic processes. Throughout Solar System history planetary bodies have been pummeled by asteroids and comets, and it is thought that these impacts brought volatile elements and precious metals to the early Earth- with this new technique we will be able to understand the nature of the material that has been added to the planets since their formation, and so better understand the events that made our planet habitable and, indeed, hospitable to complex life.

对行星体样本的详细分析是了解地球和更广泛太阳系故事的核心。为此，人们开发了大量专门的仪器，其中许多现在被用于更直接的方式——寻找资源，了解我们的文明对环境的影响，追踪化学物质在我们体内的运动途径，引起和治疗疾病。在每种情况下，当使用多种不同的技术来理解单个样本时，取得了最大的进展。此外，从每次分析中提取最大数量的有用信息以正确理解其含义是至关重要的。在曼彻斯特，我们有各种各样的专业仪器，其中一些是世界上独一无二的，因为我们自己开发了它。在这项建议中，我们寻求资助一项技术，以补充我们现有的能力。该仪器使用非常短的激光脉冲来切割样品表面上小于十分之一毫米的斑点。这些碎片被流过样品表面的气体带入质谱仪，质谱仪分析其中存在的元素。当这项技术的信息与我们其他分析技术的输出相结合时，我们将有一种新的有力的方法来研究从太阳系中第一批尘埃的凝结到像地球这样的行星形成的过程的性质和顺序。我们还将能够了解其他行星体的表面，特别是火星和月球，是如何通过火山过程形成和演化的。在整个太阳系的历史中，行星体一直受到小行星和彗星的撞击，人们认为这些撞击将挥发性元素和贵重金属带到早期的地球上——有了这项新技术，我们将能够了解自行星形成以来被添加到行星上的物质的性质，从而更好地了解使我们的星球适合居住，实际上适合复杂生命的事件。
