「地球周回軌道におけるアストロバイオロジー実験研究チーム」活動報告

第26回宇宙利用シンポジウム(2010年1月25日-26日, 宇宙航空研究開発機構宇宙科学研究本部相模原キャンパス)

The Twenty-sixth Space Utilization Symposium (January 25-26, 2010: ISAS/JAXA Sagamihara, Japan)

Activities of the JAXA Research Team "Astrobiology Experiments in Earth Orbit" were reported. This research team was originally organized as a working group in 2004, and has been discussed possible experiments on astrobiology by utilizing the ISS and other facilities since then. In 2006, we picked up one of the subjects, and it was proposed to JAXA as the "Tanpopo mission". In 2009, we discussed future missions to study the distribution of microorganisms in space: They include Earth orbits of lower and higher altitude, the Moon, Mars, Europa and Titan. It is important to develop new sensitive techniques to detect and characterize organic compounds and microorganisms. STXM-XANES technique is one of the promising one for ultra micro samples returned from space. Detection of D-/ L-amino acids is important to discuss possible presence of life. New possible separation and pretreatment techniques were discussed. We also discussed domestic and international astrobiology networks.
