Paper Abstract

Starshades have been shown to hold the potential to reveal Earth-like planets around nearby stars and to allow detailed follow-up study including spectroscopy. Ideally this would be performed with a starshade in excess of 50m diameter and a telescope over 4m in diameter. However, such a flagship-class mission is unlikely to be realized in under fifteen years. But much can be accomplished in substantially less expensive missions. I will review the alternatives and provide an assessment of various architectures and what they can accomplish. These alternatives will include using JWST as the telescope, using small dedicated telescopes, and using smaller starshades.
