项目摘要

The magnetised plasma streaming outward from the Sun creates a cosmic plasma structure termed 'the heliosphere', extending out to 100 au. Galactic Cosmic Rays (GCRs) originating from supernovae and pulsars, and Solar Energetic Particles (SEPs) sourced from the Sun, present a major radiation risk for spacecraft and astronauts travelling out beyond the protective influence of the Earth's magnetic field. Their propagation through the heliosphere to near-Earth space is essential to characterise to enable future exploration efforts to the Moon and beyond. The project will simulate the propagation of GCRs and SEPs through the heliosphere using models of the solar wind and coronal mass ejections and compare to space-based measurements. A focus for this project will be the upcoming Lunar Gateway Space Station, due to launch in 2025, which will act as a base for future exploration of the lunar south-pole and Mars. Specific areas of focus include modelling an increasingly representative heliosphere using the latest observational constraints; examining relativistic particle access to cis-lunar space and Lunar Gateway orbits; and modelling the interactions of energetic particles with coronal mass ejections. This project benefits from involvement in the NASA/ESA/CAS/JAXA Gateway Heliophysics and Space Radiation Working Group associated with the Lunar Gateway and Artemis programme and associated travel may form a part of the project.

磁化的等离子体从太阳向外流出，形成了一种称为“ Heliosphere”的宇宙等离子体结构，延伸至100 au。源自超新星和脉冲星的银河宇宙射线（GCR），以及来自太阳的太阳能颗粒（SEP），对航天器和宇航员的主要辐射风险和宇航员具有超出地球磁场保护性影响的主要辐射风险。它们通过直射到近地球空间的传播对于使未来的探索工作对月球及以后的探索工作至关重要。该项目将使用太阳风和冠状质量弹出模型模拟GCR和SEP通过Heliosphere的传播，并将其与空间测量值进行比较。该项目的重点将是即将推出的Lunar Gateway太空站，该站将于2025年推出，该站将成为对Lunar South-Pole和Mars的未来探索的基础。重点的特定领域包括使用最新的观察性约束对日益代表性的Heliosphere进行建模；检查相对论的粒子进入顺式节空间和月球门轨道；并建模能量颗粒与冠状质量弹出的相互作用。该项目受益于参与NASA/ESA/CAS/JAXA网关Heliophysics和空间辐射工作组与Lunar Gateway和Artemis计划以及相关旅行相关的空间辐射工作组，可能会构成该项目的一部分。
