备注:
The WOPA committee members are alphabetically listed as authors above. Each chapter was authored by a working group with their full membership listed in Appendix D. Conference participants are listed in Appendix B. Editor is Patti Wieser. 130 pages, 10 chapters, 4 appendices, 26 figures
Major scientific questions and research opportunities are described on 10 unprioritized plasma astrophysics topics: (1) magnetic reconnection, (2) collisionless shocks and particle acceleration, (3) waves and turbulence, (4) magnetic dynamos, (5) interface and shear instabilities, (6) angular momentum transport, (7) dusty plasmas, (8) radiative hydrodynamics, (9) relativistic, pair-dominated and strongly magnetized plasmas, (10) jets and outflows. Note that this is a conference report from a Workshop on Opportunities in Plasma Astrophysics (WOPA, https://w3.pppl.gov/conferences/2010/WOPA/) in January 2010, that attracted broad representation from the community and was supported by the U.S. Department of Energy, National Aeronautics and Space Administration, National Science Foundation, American Physical Society's Topical Group for Plasma Astrophysics and Division of Plasma Physics, and Center for Magnetic Self-Organization in Laboratory and Astrophysical Plasmas. Although there has been much planning and many developments in both science and infrastructure since the report was written, most of the motivation, priorities, problems and technical challenges discussed therein remain unaddressed and are relevant at the time of posting.

Space Plasma Physics Science Opportunities for the Lunar Orbital Platform -Gateway
月球轨道平台网关(Lunar Orbital Platform-Gateway,LOP-Gateway或简称Gateway)是一个载人平台,将由美国宇航局和包括欧空局在内的国际合作伙伴组织从2020年代中期开始在月球附近组装和运营。它将为基础和应用科学研究提供新的机会。月球是研究深空空间等离子体环境的独特场所。此外,月球表面和表面边界外逸层与该环境相互作用,构成了一个复杂的多尺度相互作用系统。本文审查了网关上外部安装的有效载荷在空间等离子体物理学、太阳物理学和空间天气领域提供的机会,还审查了空间环境对月球附近有人居住平台的影响。然后介绍进行这些空间等离子体测量和观测所需的模型有效载荷的概念设计。结果表明,Gateway非常适合于空间等离子体物理研究。它允许处理一系列具有多学科层面的科学目标。
威斯康星等离子体天体物理实验室(WiPAL)是一个灵活的用户设施,旨在研究一系列与天体物理学相关的等离子体过程以及模拟天体物理系统的新几何形状。由强钐钴永磁体构造的多尖磁桶现在限制10 m $^3$,完全电离,磁场自由等离子体在球形几何形状。等离子体参数$ T_{e}\approx5$到$20$ eV和$n_{e}\approx10^{11}$到$5\times10^{12}$ cm $^{-3}$为一系列天体物理实验提供了理想的测试平台,这些实验包括自激发电机、无碰撞磁重联、喷流稳定性、恒星风等。本文描述了WiPAL的功能以及在操作和规划阶段的几个实验,为未来用户展示了各种可能性。
