To address the question whether interplanetary migration of terrestrial microbes are possible, we have proposed and prepared the space capture and space exposure experiments of terrestrial microbes as TANPOPO mission on the Exposure Faculty of Japanese Experiment Module of International Space Station. In this mission, we are going to expose microbes in space for one to three years. There are harsh environmental factors (vacuum, high UV irradiation, ionization radiation, and so on) in space. We have selected the species that show high tolerance to the space conditions. We are going to use UV- and radiation-resistant deinococcal species: four stains of ${it Deinococcus radiodurans}$ (R1, KH311, rec30, and UVS78), ${it D. aerius}$ TR0125, and ${it D. aetherius}$ ST0316. We summarize survivability of deinococcal species for UV-irradiation, heavy ion-irradiation, high vacuum, and periodical change of temperature. Then, we evaluate survivability of deinococcal species in space after one year.
