The latest findings in origin, biological effects and shielding of the space ionizing radiation (SIR) are reviewed. It is stressed that after the impending implementation of artificial gravity, SIR could become the most serious concern for deep space travelers. SIR is more effective in induction of the genome- and cell-associated damages, compared with the conventional radioactive sources. The shielding of SIR is augmented due to the secondary spallation S -radiation and possible cooperation with weightlessness and other negative impacts of a space flight. The panspermia concept postulating the existence of living organisms, e. g. bacterial spores, in space and their natural interplanetary transportation is discussed.
