LIFE is a project initiated in 2017 and officially kicked-off in 2018 to
develop the science, technology and a roadmap for an ambitious space
mission that will allow humankind for the first time to detect and
characterize the atmospheres of dozens of warm, terrestrial extrasolar
planets. We show how LIFE can be used for bio- and technosignature
detection in statistically significant numbers that can be used to
constrain the factors of the Drake equation such as the fraction of
habitable planets on which life actually appears.
