Preliminary Findings from the NASA Exoplanet Exploration Program's Technosignature Survey

Building on lessons learned from the 2018 NASA Technosignatures Workshop, the NASA Exoplanet Exploration Program launched a Technosignatures Survey in 2021 as a community-informed effort to identify how NASA and private partners can most effectively support technosignature research. Now nearing completion, the study has cataloged over three dozen distinct detection strategies, ranging from established SETI methods to novel concepts still lacking formal search strategies, and evaluated them across a standardized set of criteria, including technological needs, observing strategies, facility requirements, and hypothesized extraterrestrial motivations. In this talk, we will present key outcomes from the survey, with a focus on findings relevant to future NASA missions and activities. We will discuss which approaches have already been implemented, which are achievable with modest additional resources, and which would benefit most from targeted technological and programmatic development. We will also highlight the top technology and non-technology needs identified across the surveyed approaches, gaps in the existing literature, and connections to current and future observatories such as JWST, Roman, Rubin, and the Habitable Worlds Observatory. Ultimately, this work is intended to serve as both a strategic planning tool and a public-facing resource for NASA, private funders, and new investigators entering the field.
