We discussed possible subjects of astrobiological experiments in Earth orbit, including (1) formation and alteration of organic compounds in space environments, (2) survivability of terrestrial microorganisms in space environments, (3) Search of microorganisms in Earth orbit near ISS (International Space Station), (4) observation of autonomous biological system (microcosms) in space environments, and (5) space quarantine by using ISS. We performed some preliminary experiments on ground. Organic compounds and microorganisms were irradiated with high energy particles, UV light or X rays from accelerators. They were also subjected to high-velocity impacts by using a two stage light gas gun to verify possible capture of organic compounds and/or microorganisms in Earth orbit., 資料番号: AA0063349117}, pages = {410--413}, 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 = {地球周回軌道におけるアストロバイオロジー実験:宇宙環境下での有機物・微生物・生態系を探る}, year = {2007} }
