“…This revelation, with subsequent explanation, 2 opened the door to experiments at larger separations to test at flight-like Fresnel numbers. Starshades have been tested over kilometers of separation on dry lakebeds [34][35][36] and with a heliostat on Kitt Peak. 37,38 Similarly, the optical experiments of Harness et al were conducted in air.…”

This special section is dedicated to starshades: science, engineering, technology, and programmatics. Our reasons for organizing this special section are several fold. First as a new technology and with research accomplished in many institutions, recent results are widely scattered in the literature. As such, we see great value in colocating many of the most recent results. This guest editorial summarizes the 19 contributed papers as the result of a special call for papers. Since this is a rapidly maturing technology, we wanted to colocate a primer with the most current work in the field. It is hoped that this primer will provide a tutorial to the starshade concept and pathway to the literature not in this section. In doing so, we hope to widen the starshade community in terms of engineering and scientific engagements. This tutorial takes the form of a dialogue, where frequently asked questions are answered.

“…S TARSHADES are a promising concept for achieving the necessary level of starlight suppression needed to detect habitable zone exoplanets [1][2][3]. By deploying a separate spacecraft along the line of sight (LOS) of a space telescope to a target star, a shadow is cast onto the telescope pupil, blocking on-axis starlight while passing off-axis exoplanet light.…”
