"NASA’s Mars Architecture Team (MAT) has recently developed a collection of concepts to assess the capabilities and constraints presented by architectures incorporating large-scale Mars In-Situ Resource Utilization (ISRU) propellant production. The focus of this manuscript is on the concept design of chemical propellant-based transportation systems including a dual role lander/ascent vehicle and an in-space transporter. Mission performance analyses performed during a recent design analysis cycle derived the 300,000 kg propellant production capacity utilized for preliminary concept designs of enabling surface ISRU systems, power systems, fluid handling systems, and their concept of operation, detailed in companion papers."
