Abstract

This paper presents the conceptual design and analysis of a rover-based mission emergency mitigation system intended to increase the range, scientific capability, and safety of manned lunar surface exploration while only requiring a modest increase in capability over the Apollo mission designs. The system is intended to enable the safe return of two astronauts back to the lunar operational base in the event of two types of failures: rover failures and medical emergencies and/or suit failures. The proposed system increases fault tolerance with the addition of an emergency inflatable structure and an environmental control and life support system on the lunar rover to mitigate a wide range of suit and rover failures. The environmental control and life support system on the rover can be connected to the emergency inflatable to provide a habitable environment in the event of suit failure or connected to the astronaut’s portable life support system to provide additional consumables in the event of rover failure. The mass and volume analyses of each subsystem are integrated to generate a total system mass of 26.91 kg and volume of 86.10 L, both of which can be accommodated on the Apollo Lunar Roving Vehicle design without requiring additional carrying capacity.
