Significant progress has been made to NASA’s Moon to Mars campaign over the last several years, which drives changes to the agency’s current human exploration strategy. With Strategic Analysis Cycle 2021 (SAC21) the team was asked to consider new areas of the trades space not fully understood in the past. Specific to the Mars Ascent Vehicle (MAV), the team was asked to consider a concept based on a nitrogen tetroxide (NTO) and mono-methyl hydrazine (MMH) two stage propulsion system which would utilize surface propellant transfer, as opposed to In Situ Resource Utilization (ISRU). The vehicle supports two crew members from the surface up to 84 hours nominally. This paper presents further details of the current MAV reference design used in NASA’s SAC21, including descriptions of the operations, configuration, subsystem design, and vehicle mass summary. Additional detail is also provided on rational that drove specific design changes since the last MAV concept, published in 2019.
