Active optics for a Science mission

To look for Earth-sized exoplanets, we need a resolution 2–3 orders of magnitude higher than we can achieve now. This requires bigger, deployable mirrors.

Led by Thales Alenia Space, an ESA Discovery & Preparation study aimed to identify the technical challenges associated with active optics for deployable space mirrors, design an active correction loop, and define a technological roadmap towards developing such a loop.
