A new campaign on ESA’s Open Space Innovation Platform – seeking out community input to accelerate ISRU – aims to identify knowledge and technical gaps in our current lunar space resources value chain. Such gaps shall in turn define future contests supported by ESA in partnership with the European Space Resources Innovation Centre, ESRIC, in Luxembourg. This Identifying Challenges along the Lunar ISRU Value Chain campaign invites people to submit one or more ideas across three areas tackling crucial steps in the extraction of lunar resources.
