Paper Abstract

Detecting life-bearing Earth-like planets (ELPs) is one of NASA's highest priority goals. In this paper we derive the wave-front requirements for optical detection of ELPs with an 8-m space telescope and coronagraph. We will present detailed simulations that show that an 8-m coronagraphic space telescope can detect Earth-sized planets around nearby stars, provided that the wavefront at the detector is corrected to an RMS error of ~λ/3000. We use the derived wavefront error to set requirements for a deformable mirror based on micro-electro-mechanical systems technology.
