The search for exoplanets is an important goal for the Astronomy community in the next decade. We discuss the feasibility of finding terrestrial planets around nearby stars using direct-detection methods. The probability of finding a planet in the habitable zone around a given star depends on its brightness and distance from Earth, the fraction of stellar systems that contain terrestrial planets (ηEarth), and the characteristics of the observatory. We discuss the available target stars and the completeness of a search for terrestrial exoplanets given different mission constraints.
New Worlds Observer (NWO) is a two-spacecraft mission that consists of an external starshade and an UV-optical space telescope, flying in tandem.
In this paper, we focus on NWO's ability to complete a feasible observing schedule designed to find and characterize 30 Exo-Earths around nearby stars (if ηEarth = 1). NWO offers the ability to create flexible, adaptable observing schedules to meet a variety of observing goals.
