An overview of the conceptual study of spacecraft used for validating technologies which will be necessary for manned space development conducted by Japan in the future is presented. An Environmental Control and Life Support System (ECLSS) and two-phase liquid loop radiator experiment equipment were selected as the major and optional equipment to be installed onboard the manned engineering test satellites, respectively. Mission items for ECLSS experiment equipment were extracted and traded off from the following on-ground technologies: (1) technology for removing toxic substances, offensive substances, and fine particles from the atmosphere; (2) N2 and O2 partial pressure control and CO2 removal technologies; (3) gas sensing technology; and (4) temperature and humidity control technology. Comparison was conducted on three base-line configurations such as follows: (1) pressurized module (expendable) plus bus section (expendable); (2) pressurized module (retrievable) plus bus section (expendable); and (3) pressurized module (expendable) plus bus section (expendable) plus recovery section. The results of the review on the satellite system base on configuration of the above case (1) are outlined.
