摘要

An orbiting starshade working with 30-m class ground-based telescopes would enable observations of molecular oxygen and water on an exo-Earth. The starshade provides the needed contrast and the telescope with advanced adaptive optics provides angular resolution, reduction of the sky background, imaging, and spectroscopy.
