摘要:

除了传统的SETI无线电搜索之外,现在还有新的和独特的机会来寻找技术特征(TS),这是近年来系外行星科学和观测能力的巨大进步所推动的。公共和私营空间机构可能特别有兴趣了解社区对利用当前或即将出现的技术进行未来TS搜索的最佳方法的看法。本报告就是朝着这一方向作出的努力。我们提出了一套可能的任务概念,旨在寻找TS,虽然这些任务提供的数据也将有利于天体物理学的其他领域。我们引入了一个新颖的框架来以定量的方式分析TS的广泛多样性。这个框架是基于遗迹尺度的概念,这是一个新的参数相关的TS宇宙足迹的规模,连同潜在的目标,这样的TS可以搜索的数量,以及它是否是连续的时间。

英文摘要:

New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet science and observing capabilities in recent years. Space agencies, both public and private, may be particularly interested in learning about the community's views as to the optimal methods for future TS searches with current or forthcoming technology. This report is an effort in that direction. We put forward a set of possible mission concepts designed to search for TS, although the data supplied by such missions would also benefit other areas of astrophysics. We introduce a novel framework to analyze a broad diversity of TS in a quantitative manner. This framework is based on the concept of ichnoscale, which is a new parameter related to the scale of a TS cosmic footprint, together with the number of potential targets where such TS can be searched for, and whether or not it is continuous in time.
