This consolidated grant supports a programme of STFC-funded research into the physics of various plasma environments within our solar system. The programme is thus divided into four distinct projects, the aims of which are as follows:- Project 1 aims to determine the extent to which internal magnetospheric processes disrupt the solar wind control of large-scale magnetospheric dynamics and ensuing space weather, by considering phenomena that decouple the solar wind-magnetosphere-ionosphere system.- Project 2 will investigate lunar dust charging and dynamics as well as collective behaviour of dusty plasmas applicable to other bodies in the solar system (e.g. Saturn's rings, comets). This will be done by further development of a 3D particle-in-cell simulation developed at Lancaster that will include all relevant forces, distributions and fields to fully capture the physics. - Project 3 will exploit data from Mars- and Saturn-orbiting spacecraft to study magnetic flux ropes, a phenomenon linked to the loss of planetary atmospheres from unmagnetised bodies, to understand their role in solar-planetary coupling.- Project 4 will identify how energy from the Sun affects Saturn, through the study of Saturn's auroral emissions observed by Cassini and the Hubble Space Telescope under the extremes of solar cycle activity.

这笔综合赠款支持 STFC 资助的一项研究项目，该项目涉及太阳系内各种等离子体环境的物理学。因此，该计划分为四个不同的项目，其目标如下： - 项目1旨在通过考虑解耦太阳风-磁层-电离层系统的现象，确定内部磁层过程扰乱太阳风对大规模磁层动力学和随之而来的空间天气的控制的程度。- 项目2将研究月球尘埃充电和动力学以及适用于尘埃等离子体的集体行为。 太阳系中的其他天体（例如土星环、彗星）。这将通过进一步开发兰卡斯特开发的 3D 细胞内粒子模拟来实现，该模拟将包括所有相关的力、分布和场，以充分捕捉物理现象。 - 项目 3 将利用来自火星和土星轨道航天器的数据来研究磁通绳，这是一种与未磁化天体失去行星大气层有关的现象，以了解它们在太阳-行星耦合中的作用。- 项目 4 将通过研究卡西尼号和哈勃空间观测到的土星极光发射来确定来自太阳的能量如何影响土星。 太阳周期活动极端情况下的望远镜。
