Research Abstract |
We have investigated the resistivility of life against various kinds of the extreme environmental factor in the space. Materials used for the present study were the 'tun' of Milnesium tardigradum, spores and leaves of mosses, embryos of Artemia, and plant seeds. These materials were exposed to vacuum (1×10^<-3>Pa), nitrogen-exchanged air (1Pa), and ultrahigh pressure (7.5GPa), and resistivility was assessed. We have issued a manual for educational guidance for students.
