Excellent microgravity and less constraint on mission duration are the two major advantages of small satellite compared to manned spacecraft, such as the International Space Station. Target space experiment could be certain crystallization that require a long duration to process, or critical phenomena realized under good microgravity. For space life science, response of whole body and ecological system, which are exposed to space environment for a period of multiple generation. Generic requirements of biological payloads are itemized, and issues associated with conceptual design of the satellite system and operation are discussed., 資料番号: AA0046917047}, pages = {152--154}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {小型回収衛星と宇宙環境利用}, year = {2004} }
