In order to achieve a sustainable human presence on the Moon, Mars, and beyond, humanity must develop the capability to provide as close to 100% supply of resources in-situ as possible. Achieving this goal will require development of technologies to locate, extract, process, generate, and utilize said resources. To date, contemporary in-situ resource utilization-based space exploration architectures typically focus on the production of resources that have the most value for initial use in space such as O2, H2, and H2O for the production of propellant and life support consumables [1]. However, critical metals indispensable to the terrestrial global economy such as Ni, Cu, Co, and the platinum-group elements will also likely be required to support the endeavor of becoming a multi-planetary species [2,3], and on this topic Mars becomes the focus. Based off compositional and petrographic similarities between terrestrial mantle-derived mafic/ultramafic magmas, meteorites known to come from Mars, and the physicochemical characteristics of the Martian surface, it is likely that massive and disseminated sulfide ores, which host these precious resources, were deposited at or near the surface [4,5]. In order to validate this belief, a more thorough exploration campaign is required to properly assess whether Mars is an ore-rich planet. Thus, this paper will provide an overview on the current state of knowledge and technologies available for prospecting for magmatic sulfide ores on Mars, with a particular focus on the capacity and necessity of integrating sustainable practices in upcoming space missions focused on in-situ resource utilization. Additionally, potential use cases of metals derived from magmatic sulfide ores in the space industry are considered.
