The gaps that this call will help identify will serve as the basis to define the themes of the next ESA and ESRIC Space Resources Challenges, following on from the initial joint challenge looking into the use of rovers to prospect resources.

The solutions identified via the various challenges that participants will help us define could, in the future, be tested on the ISRU Pilot Plant, an end-to-end terrestrial demonstrator plant intended to validate all necessary ISRU steps in practical terms, on Earth, and then, potentially one day, in space.
