Abstract

The search for Exo-Earth biosignatures is the ultimate, and most challenging, scientific objective of the Habitable Worlds Observatory. The Exoplanet Spectroscopy Technologies Project (abbreviated ExoSpec) is dedicated to maturing three subsystem technologies that can enable the characterization of directly imaged exoplanets: integral field spectrographs (IFS), radiation-tolerant photon counting CCD detectors, and parabolic deformable mirrors (PDMs). While we advance these subsystem technologies through separate laboratory prototype demonstrations, we are also assessing their impact in terms of scientific yield at the system level through science-based end-to-end modeling and spectral retrieval simulations. This modeling pipeline provides a framework to guide engineering trades. This proceeding reports on the status of the ExoSpec effort, key technology demonstrations planned, the current testbed configuration, and technological progress to date.
