该项目建立全球合作，测试接收模拟地外信号的技术管道与协议，将深空技术整合到SETI搜索中，旨在实施IAA SETI委员会的探测后流程协议。
AI 中文摘要
地外智能搜寻（Search for Extraterrestrial Intelligence，SETI）计划旨在寻找地外智能存在的证据，SETI科学家主要通过在无线电或光学波段搜寻技术信号来实现这一目标。国际宇航科学院（IAA）SETI委员会一直在制定相关协议，为实际接收到地外信号的情况提供指导，这些协议明确了确认信号真实性及其地外属性的流程，以及委员会在科学界和公众中管理该发现的角色，针对当前SETI搜索中与设备管理、所用方法相关的科学问题。《太空符号》第二部分项目旨在积极吸引全球SETI社区和全球望远镜网络参与，让科学设施做出响应并协调以确认所接收信号的地外属性，该项目发展了跨学科工作《太空符号》中已采用的部分社会、科学和技术方法。在此，我们建立了SETI科学家、射电天文台与欧洲空间局（ESA）之间的全球合作，以测试通信和技术管道及协议，这些管道和协议用于全球射电望远镜网络接收模拟地外信号，我们还利用了ESA的航天器进行系统验证。《太空符号》第二部分旨在通过与ESA、SETI研究所及意大利天体物理研究所合作的结构化持续计划，进一步将深空技术应用于SETI搜索，该项目将旨在上演并测试整个探测后流程，实施IAA SETI委员会所设想的协议。
英文摘要
The Search for Extraterrestrial Intelligence programme aims to find evidence of extraterrestrial intelligence. SETI scientists pursue this objective by searching for technosignatures primarily in the radio or optical spectrum. The IAA SETI Committee has been developing protocols to offer guidelines in case of an actual extraterrestrial signal reception. These protocols establish procedures to confirm the authenticity of the signal and its actual extraterrestrial nature, as well as the committee's role in managing the discovery in relation to the scientific community and the general public, targeting scientific queries in relation to the management and development of equipment and methodologies employed in current SETI search. The project A Sign in Space part 2 aims to actively engage the global SETI community and the global telescope network, with scientific facilities responding and coordinating themselves to confirm the extraterrestrial nature of the received signal. The project develops some of the societal, scientific and technological methodologies already employed in the interdisciplinary work A Sign in Space. Here, we established a global collaboration between SETI scientists, radio observatories and the European Space Agency to test the communication and technological pipeline and protocols leading to the reception of a simulated extraterrestrial signal by a network of radio telescopes across the globe. We also employed an ESA spacecraft for system validation. A Sign in Space part 2 aims to further implement deep space technologies in SETI search through a structured and sustained programme, in collaboration with ESA, the SETI Institute and the Italian Institute for Astrophysics. The project will aim to stage and test the entire Post Detection procedure, implementing the protocol as envisioned by the IAA SETI committee.
