In the framework of demonstrating the feasibility of small and low-cost missions by increasing operational autonomy, ESA proposed a mission called PROBA (PRoject for On-Board Autonomy). Proba intends to demonstrate the benefits of autonomy and to validate the supporting advanced technologies in orbit.

Micro-Cameras & Space Exploration is involved in delivering a micro-camera for the High Resolution Camera (HRC) for Proba Telescope. HRC performs Earth observations with a resolution of 5-10m/pixel, realising a mosaic of images of European countries.

Imaging of the Earth limb can illustrate the modest volume of the atmosphere and the importance of its equilibrium. Signatures of life and human activities on the whole Earth scale can be very educational. They illustrate environment aspects and the fragility of the biosphere. Night-side Earth observations can be obtained to outline cities, fires, light pollution.
