Estimation of Life-support Systems Required by Different Material Circulation Systems at Manned Lunar Base Camp

Key Points

The aim is to estimate the life support systems needed for a manned lunar base camp. The report compares different material circulation techniques to identify the best options.
Calculated weight and volume of essential life support equipment
Compared three scenarios: fully expendable, physicochemical circulatory, and vegetative circulatory
Analyzed previous findings by Sato et al. regarding lunar habitation
Identified material circulation systems required for sustained human presence on the Moon
Compared volume and weight metrics across the three life support system scenarios
Outlined potential implications for transportation costs and lunar mission feasibility

Abstract

Plans are underway, such as the U.S.-led Artemis mission, for humankind to once again aim for the Moon. Unlike the International Space Station (ISS), currently serving as humanity's orbital outpost, the Moon stands over 1,000 times farther from Earth, making transportation costs a pivotal consideration for lunar missions. This report follows Sato et al.'s previous study on establishing a manned lunar base camp. This time, the focus is on the crucial life support systems for sustained human presence. We calculated and compared the weight and volume of essential life support equipment across three scenarios: fully expendable, physicochemical circulatory (akin to the ISS), and vegetative circulatory types.
