The New Worlds Observer is a flagship-scale terrestrial planet finding and characterizing mission using an external occulter known as a starshade. The starshade is a separate space vehicle from the observing telescope; the starshade performs all the necessary starlight suppression to enable high contrast imaging of terrestrial exo-planets. While effective as a flagship-scale mission designed to fulfill and exceed the requirements of the TPF mission, the starshade architecture is flexible and can accommodate a variety of design and cost categories. We present in this paper the selection and design process that leads to wide range of mission configurations from medium to flagship class, as well as missions that uses existing space telescopes. We discuss, in particular, starshade size, telescope-to-starshade separation, and telescope diameter. We will present the architecture for probe or medium scale missions, starshade stand-alone missions with existing telescopes, and starshades for future, large telescopes.
