In many human Mars exploration architectures, a Mars Ascent Vehicle (MAV) is used at the end of a surface stay to transport crew from the Martian surface to a waiting in-space transportation vehicle. It is possible for this transportation vehicle to be placed in any of several different Mars orbits, the selection of which drives the flight duration of the MAV from launch to docking and the amount of propellant required on the transportation vehicle to reach the same orbit. This paper identifies existing NASA standards and supplies habitability subject matter expert recommendations for the human habitation capabilities of the MAV as a function of flight duration. Living and working functions that may potentially be carried aboard a MAV are assessed. Flight durations considered include up to 8 hours, 8-24 hours, 1-2 days, 2-3 days, 3-4 days, and 4-7 days, which book end flight durations necessary to reach the transportation vehicle at different possible Mars orbits. This analysis will determine if there are key durations that serve as significant break points in required MAV capability.
