  This report is the product of the NASA Technosignatures Workshop held at the
Lunar and Planetary Institute in Houston, Texas, in September 2018. This
workshop was convened by NASA for the organization to learn more about the
current field and state of the art of searches for technosignatures, and what
role NASA might play in these searches in the future. The report, written by
the workshop participants, summarizes the material presented at the workshop
and incorporates additional inputs from the participants. Section 1 explains
the scope and purpose of the document, provides general background about the
search for technosignatures, and gives context for the rest of the report.
Section 2 discusses which experiments have occurred, along with current limits
on technosignatures. Section 3 addresses the current state of the
technosignature field as well as the state-of-the-art for technosignature
detection. Section 4 addresses near-term searches for technosignatures, and
Section 5 discusses emerging and future opportunities in technosignature
detection.
