粒子加速是在许多天体物理对象中产生的基本过程，包括活动星系核、黑洞、中子星、伽马射线暴、吸积盘、太阳和恒星日冕以及行星磁层。它的无处不在意味着高能粒子渗透到宇宙中，影响着生命出现和延续的条件。在我们的太阳系中，太阳是能量最大的粒子加速器，它的邻近使它成为探索天体物理粒子加速的独特实验室。然而，尽管它很重要，但人们对太阳粒子加速背后的物理原理仍然知之甚少。SPARK任务将通过独特强大的γ射线、x射线和EUV成像以及高光谱、空间和时间分辨率的光谱学的完整组合，揭示关于粒子加速的新发现。SPARK的仪器将为观测能力提供一个台阶，使我们对太阳粒子加速及其相关现象的理解取得根本性突破，例如太阳爆发事件的演变。通过提供驱动太阳耀斑和日冕物质抛射的发生和演化过程的基本诊断，SPARK将阐明空间天气事件的潜在物理学，这些事件可能会损坏卫星和电网，扰乱电信和GPS导航，并危及太空中的宇航员。预测这类事件并减轻其潜在影响对于保护我们的地面和天基基础设施至关重要。
Particle acceleration is a fundamental process arising in many astrophysical objects, including active galactic nuclei, black holes, neutron stars, gamma-ray bursts, accretion disks, solar and stellar coronae, and planetary magnetospheres. Its ubiquity means energetic particles permeate the Universe and influence the conditions for the emergence and continuation of life. In our solar system, the Sun is the most energetic particle accelerator, and its proximity makes it a unique laboratory in which to explore astrophysical particle acceleration. However, despite its importance, the physics underlying solar particle acceleration remain poorly understood. The SPARK mission will reveal new discoveries about particle acceleration through a uniquely powerful and complete combination of γ-ray, X-ray, and EUV imaging and spectroscopy at high spectral, spatial, and temporal resolutions. SPARK’s instruments will provide a step change in observational capability, enabling fundamental breakthroughs in our understanding of solar particle acceleration and the phenomena associated with it, such as the evolution of solar eruptive events. By providing essential diagnostics of the processes that drive the onset and evolution of solar flares and coronal mass ejections, SPARK will elucidate the underlying physics of space weather events that can damage satellites and power grids, disrupt telecommunications and GPS navigation, and endanger astronauts in space. The prediction of such events and the mitigation of their potential impacts are crucial in protecting our terrestrial and space-based infrastructure.
