“…Urania: The development of dependable deployment mechanisms have been a major focus of starshade engineering. [39][40][41][42][43] The S5 technology program presented by Willems and Lisman has a number of technology milestones 44,45 that demonstrate the deployment of full-scale subsystems with sufficient accuracy and repeatability, and Arya et al present their solution to this design problem. Figure 7 shows a sequence of such a deployment.…”

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.

“…However, they did not demonstrate petal shape recovery after stowage and deployment. In 2014, Kasdin et al 17,18 demonstrated the deployment of a 12-m-diameter inner disk with four petals. The deployment accuracy of the petals was measured to be AE250 μm in the radial direction and AE500 μm in the tangential direction.…”
