Abstract:
Selected vegetables for life support are continuously produced in the lunar farming module. Inedible parts of the vegetables are decomposed and provided as the fertilizer elements for the next vegetables.In this report, contained elements in their inedible mass for recyclingare discussed for each of the four vegetables. Elements and concentration of cultural liquid which are required by each vegetable are surveyed as well.Adjustment of decomposition liquid is discussed in view of transforming inedible vegetable to cultural liquid. Authors are proposing wet oxidization as one of the decomposition methods for these inedible parts. Some adjusting sub-system is necessary here, since elements and their concentration in decomposition liquid is not enough to reproduce vegetables.This report aims to clarify the composition of a vegetable production system for an eight-member
