Enceladus, a satellite of Saturn, with its radius of 250 km, is the small est geologically active celestial body in the Solar System. My model of core origin and evolution in dicates that for hundreds of My after accretion Enceladus was an appropriate body for an origin of life. I continue consideration of the hypothesis that Enceladus was a cradle of life in the Solar System. I found that simple organisms could be ejected in icy grains into the space by volcanic jets or by meteoroid im pacts. Several mechanisms could be responsible for later transport of the grains to the early Earth and other ter res trial plan ets. Eventually I suggest that Enceladus is the most appropriate body for a cradle of life in the Solar System.
