这份白色文件概述了通过未来欧空局使命解决基本科学主题“带电粒子如何在空间等离子体中通电”的重要性。这份白色论文提出了五个引人注目的科学问题，这些问题与激波、重连、波和湍流、喷流及其组合引起的粒子碰撞有关。解决这些问题需要解决尺度耦合，非线性和非平稳性，这是现有的多点观测无法做到的。需要从一个多点、多尺度L级等离子体观测站进行现场测量，该观测站由至少七个航天器组成，覆盖流体、离子和电子尺度。等离子体天文台将使我们对粒子物理学和空间等离子体物理学的理解发生范式转变，对太阳和天体物理等离子体产生非常重要的影响。这将是继Cluster、THEMIS和MMS之后，非常庞大和活跃的欧洲空间等离子体社区的下一个合乎逻辑的步骤。作为未来欧空局2050年航行科学方案的基石任务之一，它将进一步加强欧洲在这一重要领域的科学和技术领导地位。
This White Paper outlines the importance of addressing the fundamental science theme “How are charged particles energized in space plasmas” through a future ESA mission. The White Paper presents five compelling science questions related to particle energization by shocks, reconnection, waves and turbulence, jets and their combinations. Answering these questions requires resolving scale coupling, nonlinearity, and nonstationarity, which cannot be done with existing multi-point observations. In situ measurements from a multi-point, multi-scale L-class Plasma Observatory consisting of at least seven spacecraft covering fluid, ion, and electron scales are needed. The Plasma Observatory will enable a paradigm shift in our comprehension of particle energization and space plasma physics in general, with a very important impact on solar and astrophysical plasmas. It will be the next logical step following Cluster, THEMIS, and MMS for the very large and active European space plasmas community. Being one of the cornerstone missions of the future ESA Voyage 2050 science programme, it would further strengthen the European scientific and technical leadership in this important field.
