The Astro2020 report outlines numerous recommendations that could significantly advance technosignature science. Technosignatures refer to any observable manifestations of extraterrestrial technology, and the search for technosignatures is part of the continuum of the astrobiological search for biosignatures. The search for technosignatures is directly relevant to the "World and Suns in Context" theme and "Pathways to Habitable Worlds" program in the Astro2020 report. The relevance of technosignatures was explicitly mentioned in "E1 Report of the Panel on Exoplanets, Astrobiology, and the Solar System," which stated that "life's global impacts on a planet's atmosphere, surface, and temporal behavior may therefore manifest as potentially detectable exoplanet biosignatures, or technosignatures" and that potential technosignatures, much like biosignatures, must be carefully analyzed to mitigate false positives. The connection of technosignatures to this high-level theme and program can be emphasized, as the report makes clear the purpose is to address the question "Are we alone?" This question is also presented in the Explore Science 2020-2024 plan as a driver of NASA's mission.
This white paper summarizes the potential technosignature opportunities within the recommendations of the Astro2020 report, should they be implemented by funding agencies. The objective of this paper is to demonstrate the relevance of technosignature science to a wide range of missions and urge the scientific community to include the search for technosignatures as part of the stated science justifications for the large and medium programs that include the Infrared/Optical/Ultraviolet space telescope, Extremely Large Telescopes, probe-class far-infrared and X-ray missions, and various facilities in radio astronomy.

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。
