The PRO-ACT project studies, designs and develops the establishment of a lunar base with the support of a multi-robotic platform, entailing different features, tasks and capabilities. The activities are inline with the preparation of the commercial exploitation of in-situ resources and planetary exploration research by assembling an ISRU (In-Situ Resource Utilisation) system tested in a lunar analogue setting. The vision of PRO-ACT is based on the extraction of oxygen from lunar regolith which serves as oxidizer for fuel and artificial atmosphere generation for habitats and 3D printing of relevant structures using regolith for construction purposes.
