“…The survival of spores exposed only to vacuum and freezing was about 90%. According to the target theory [20], the plot can be generally interpreted as a survival curve indicating a cumulative action of radiation analogously as in the case of slow electrons for which similar survival curves were obtained [21,22]. This means that particular spores are inactivated by various numbers of impinging ions.…”

The panspermia hypothesis is concerned with the dissemination of life in space in the form of simple micro-organisms. During an interplanetary journey the micro-organisms are subjected to the action of, among others, the solar wind. We have simulated experimentally such conditions bombarding frozen bacterial spores with low-energy hydrogen ions. On the basis of the results obtained and our earlier research, a new look at the panspermia hypothesis is discussed.
