Stratospheric Satellite
The purpose of our research was to study regeneration of brown planaria (<i>Dugesia tigrina</i>) and development of <i>Danio rerio</i> lavrae under the various stratospheric factors and after the exposure. Also, the purpose was to study creation of a stratospheric satellite as a platform for experiments. The relevance of this study is due to the increasing importance of the transporting mission of living objects from Earth to space stations or other planets, namely, the search for optimal conditions to ensure the survival of various species of living organisms in space.
