Abstract
Work progresses on the design of a sixty by 8-meter diameter telescope. This 77+ m diameter, optically phase controlled, almost-filled aperture interferometer can see atmospheric biomarkers and even the thermal footprints from Earth-like civilizations on exoplanets. This talk describes the motivation, enabling new technologies, and status of the group now planning the Colossus telescope.
