In this paper we present a novel design for a very large space-based optical interferometer that can be manufactured and launched within the next five years. The Planet Seeker Interferometer builds on previous work on laser-linked and multipart telescopes, such as the Hypertelescope and Fresnel Imager, as well as recent work on laser etching of thin-film Fresnel zone plates, to enable a very robust, simple and inexpensive design. The purpose of our work here is to lay a foundation, which serves as a call to action, in order to build enthusiasm and encourage further discourse, research, and development, towards the aim of building a telescope similar to the one outlined herein within the next five years.
