Abstract

Abstract Surface-bounded exospheres result from complex interactions between the planetary environment and the rocky body’s surface. Different drivers including photons, ion, electrons, and the meteoroid populations impacting the surfaces of different bodies must be considered when investigating the generation of such an exosphere. Exospheric observations of different kinds of species, i.e., volatiles or refractories, alkali metals, or water group species, provide clues to the processes at work, to the drivers, to the surface properties, and to the release efficiencies. This information allows the investigation on how the bodies evolved and will evolve; moreover, it allows us to infer which processes are dominating in different environments. In this review we focus on unanswered questions and measurements needed to gain insights into surface release processes, drivers, and exosphere characterizations. Future opportunities offered by upcoming space missions, ground-based observations, and new directions for modelling are also discussed.

内太阳系表面外逸层研究的未来方向

表面有界的外逸层是行星环境和岩石体表面复杂相互作用的结果。在研究这样一个外逸层的产生时，必须考虑不同的驱动因素，包括光子、离子、电子和影响不同物体表面的流星体群。对不同种类物质的外逸层观测，即挥发物或耐火材料、碱金属或水族物质，为工作过程、驱动因素、表面性质和释放效率提供了线索。这些信息使我们能够调查这些尸体是如何进化的，以及将如何进化;此外，它允许我们推断哪些过程在不同的环境中占主导地位。在这篇综述中，我们关注未解决的问题和需要深入了解表面释放过程、驱动因素和外逸层特征的测量。还讨论了即将到来的空间任务、地面观测和建模的新方向所提供的未来机会。
