项目摘要

We propose a world-class programme of research that focuses on two main areas of study concerned with our solar system. The first involves study of the outer environments of the planets where the gas is in the plasma (ionized) state, such that it not only feels the gravitational pull of the planet, but also interacts strongly with its magnetic field. In the second area we seek to study the origin and development of solar system bodies, and the impact on the evolution of life, through detailed examination of the composition of samples from comets, asteroids, and Mars, that are returned by spacecraft for study at Earth, or examined in situ during planetary exploration missions.Previous work in the first area shows that the outer environments of the planets vary widely, determined by the interaction with the plasma wind that blows continuously from the Sun on the outside, and the interaction with the planet and its moons on the inside. The solar wind is prone to outbursts that can lead to magnetic storms and bright auroras at Earth, as well as varying strongly over the 11-year solar cycle, and with distance from the Sun. Its interaction with the planets then depends on whether the planet is magnetised, has an atmosphere, and has active moons orbiting close in. We will use spacecraft data to study Mercury close to the Sun that has a magnetic field but almost no atmosphere (MESSENGER mission), Mars further away that has an atmosphere but no strong magnetic field to prevent its erosion by the solar wind (Mars Express and MAVEN), and Earth at intermediate distances having both an atmosphere and a magnetic field (using data from a number of missions including the auroral-imaging IMAGE and Polar satellites, and the Iridium satellite constellation). We will also study the strongly magnetized giant planets Jupiter, Saturn, and Uranus, using data from the new Juno mission at Jupiter and Cassini at Saturn, combined with observations of the auroras at ultraviolet wavelengths using the Hubble Space Telescope and at infrared wavelengths using large ground-based telescopes. Auroras are caused by large-scale electric currents flowing between the outer environments and the upper ionized atmospheres, which communicate force between these regions. Overall emphasis will be on the complex physical processes that couple the solar wind on the outside, the magnetic field surrounding the planet (if any), and the planetary atmosphere or surface on the inside. In a related project we also propose to develop a flight-ready compact low mass ultraviolet imager that can be used to study the auroras at Earth and elsewhere, as well as for wider applications.Research on the origins and evolution of solar system bodies builds on the expertise we have developed in the microanalysis of micron-sized samples of planetary materials, through a unique combination of electron microscopy and synchrotron-based X-ray spectroscopy. Such techniques are essential due to the small amounts of material returned from solar system bodies such as S-class asteroid Itokawa (Hayabusa mission) and Comet 81P/Wild2 (Stardust mission), studies of both forming part of our programme. Analysis of such grains offers the chance to provide a direct comparison to known primitive meteorite types and to reveal the processes that shaped the earliest stages of the solar system. We will also use these techniques to study a recently discovered Martian meteorite which will allow us to constrain the thermal and water-rock interaction history in a sample of Martian impact regolith for the first time. In a related area we also propose to develop an astrobiology instrument that will be able to detect organic compounds and minerals. The primary aim will be to build a miniaturized analytical instrument that can be configured for both in-situ and remote analysis and will be suitable for inclusion in future planetary exploration missions such as those planned by NASA and ESA.
我们提出了一个世界级的研究方案,重点是与我们的太阳系有关的两个主要研究领域。第一个涉及研究行星的外部环境,其中气体处于等离子体(电离)状态,这样它不仅感受到行星的引力,而且还与其磁场强烈相互作用。在第二个领域,我们试图研究太阳系天体的起源和发展,以及对生命进化的影响,通过详细检查彗星、小行星和火星样品的组成,这些样品是由航天器返回地球进行研究的,或者在行星探测任务中进行原位检查。在第一个领域,以前的工作表明,行星的外部环境变化很大,这取决于与外部不断从太阳吹来的等离子风的相互作用,以及与内部行星及其卫星的相互作用。太阳风很容易爆发,可能导致地球上的磁暴和明亮的极光,并且在11年的太阳周期中变化很大,并且与太阳的距离有关。它与行星的相互作用则取决于行星是否被磁化,是否有大气层,是否有活跃的卫星围绕其运行。我们将利用航天器数据研究靠近太阳的水星,它有磁场,但几乎没有大气层(信使使命),火星更远,有大气层,但没有强大的磁场,以防止其侵蚀的太阳风(Mars Express和MAVEN),而地球在中间距离上既有大气层又有磁场(利用包括极光成像IMAGE和Polar卫星以及Iridium卫星星座在内的一些飞行任务的数据)。我们还将利用新的朱诺号木星使命和卡西尼号土星探测器的数据,结合哈勃太空望远镜在紫外波长和大型地面望远镜在红外波长的极光观测,研究强磁化的巨行星木星、土星和天王星。极光是由外部环境和上层电离大气之间流动的大规模电流引起的,这些电流在这些区域之间传递力量。总体重点将放在耦合外部太阳风,行星周围磁场(如果有的话)和内部行星大气或表面的复杂物理过程上。在一个相关的项目中,我们还提议开发一种可用于飞行的小型低质量紫外线成像仪,可用于研究地球和其他地方的极光,并用于更广泛的应用。通过电子显微镜和基于同步加速器的X射线光谱学的独特组合。由于从S级小行星丝川号(隼鸟使命)和彗星81 P/Wild 2号(星尘使命)等太阳系天体返回的材料数量很少,因此这种技术是必不可少的,对这两种天体的研究构成了我们方案的一部分。对这些颗粒的分析提供了与已知原始陨石类型进行直接比较的机会,并揭示了塑造太阳系最早阶段的过程。我们还将使用这些技术来研究最近发现的火星陨石,这将使我们能够首次限制火星撞击风化层样本中的热和水-岩石相互作用历史。在一个相关领域,我们还提议开发一种能够探测有机化合物和矿物的天体生物学仪器。其主要目的是建造一种小型化分析仪器,该仪器的配置既可用于现场分析,也可用于远程分析,并将适合于纳入未来的行星探索飞行任务,如美国航天局和欧空局计划的飞行任务。
