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.

从太阳向外流动的磁化等离子体形成了一个称为“日光层”的宇宙等离子体结构，其范围延伸至 100 个天文单位。源自超新星和脉冲星的银河宇宙射线（GCR）以及源自太阳的太阳高能粒子（SEP）对在地球磁场保护范围之外旅行的航天器和宇航员构成了重大辐射风险。它们通过日光层传播到近地空间对于表征至关重要，以实现未来对月球及更远地区的探索。该项目将使用太阳风和日冕物质抛射模型来模拟 GCR 和 SEP 在日光层中的传播，并与太空测量进行比较。该项目的重点将是即将于 2025 年发射的月球门户空间站，该空间站将作为未来探索月球南极和火星的基地。具体重点领域包括使用最新的观测约束对日益具有代表性的日光层进行建模；检查相对论粒子进入顺月空间和月球门户轨道的能力；并模拟高能粒子与日冕物质抛射的相互作用。该项目受益于参与与月球门户和阿耳忒弥斯计划相关的 NASA/ESA/CAS/JAXA 门户太阳物理学和空间辐射工作组，相关旅行可能构成该项目的一部分。
