The research to be carried out in our rolling grant programme focuses on the physics of the heliosphere, fundamental space physics and planetary physics. This is all underpinned by our instrument development work, enabling us to design and build space instrumentation. The measurements made by our instruments allow us to interpret and understand different space environments. Observing plasma processes out in space provides us with a way to study the fundamental processes that occur in both laboratory plasmas and astrophysical ones which are not as easy to measure. We will learn what the implications are on our climate in response to the weakest solar minimum period we have had in recent history. We will understand how Coronal Mass Ejections evolve as they travel through interplanetary space and learn to forecast better what affect they will have on us on Earth. In Fundamental Space Physics we will better understand collisionless plasmas of which interplanetary space, the region around the Earth and other planets in our solar system, are prime examples. To do this we will focus on some of the underlying key physical processes that drive the dynamics of these regions, such as turbulence and shock physics. In Planetary Physics we will focus on understanding better the different physical processes which arise in Saturn's magnetosphere: is most of the energy derived from the fast rotation of the planet; or does the solar wind have a critical role to play as well? We will resolve how Titan's atmosphere changes with time and what it is made of, which will allow us to gain a better understanding of how our own atmosphere has changed from its initial formation. By observing how some of the small icy moons of Saturn interact with the environment around them we will understand how material is outgassed from their surface and then link this to cometary outgassing and the changes that occur as the orbit of the comet changes around the Sun. The new instruments we will develop will enable us to fly low mass and low power sensors on numerous upcoming spacecraft missions. We will also develop much smaller magnetometer instruments which can be flown on balloons, landers and penetrators. These vehicles are linked to plans to study the atmospheres and surfaces of many different solar system bodies, such as our Moon, as well as moons in the outer solar system like Europa, Ganymede, Titan or Enceladus.

我们的滚动赠款方案将开展的研究侧重于日光层物理学、基础空间物理学和行星物理学。这一切都得到了我们仪器开发工作的支持，使我们能够设计和建造空间仪器。我们的仪器进行的测量使我们能够解释和了解不同的空间环境。观察太空中的等离子体过程为我们提供了一种方法来研究实验室等离子体和天体物理等离子体中发生的基本过程，这些过程不容易测量。我们将了解近代历史上最弱的太阳活动极小期对我们的气候有何影响。我们将了解日冕物质抛射在行星际空间中的演变过程，并学会更好地预测它们对地球上的我们会产生什么影响。在基础空间物理学中，我们将更好地了解行星际空间，地球周围的区域和太阳系中的其他行星的无碰撞等离子体。为了做到这一点，我们将专注于一些潜在的关键物理过程，驱动这些地区的动态，如湍流和冲击物理。在行星物理学中，我们将专注于更好地理解土星磁层中出现的不同物理过程：大部分能量来自行星的快速旋转;或者太阳风也起着关键作用？我们将解决土卫六的大气层如何随着时间的推移而变化，以及它是由什么组成的，这将使我们能够更好地了解我们自己的大气层是如何从最初的形成中变化的。通过观察土星的一些小型冰卫星如何与周围环境相互作用，我们将了解物质如何从其表面脱气，然后将其与彗星脱气以及彗星轨道变化时发生的变化联系起来。太阳。我们将开发的新仪器将使我们能够在许多即将到来的航天器任务中飞行低质量和低功率传感器。我们还将开发更小的磁力计仪器，可以在气球、着陆器和穿透器上飞行。这些飞行器与研究许多不同太阳系天体的大气和表面的计划有关，例如我们的月球，以及外太阳系的卫星，如欧罗巴，木卫三，泰坦或土卫二。
