Abstract. Despite our inability to send humans to the stars we still can send our Earth genetic material toward them, with small chance it will reach exoplanets around them. Our chance is embedding interstellar objects (ISO) which constantly trespass our Solar system with samples of organisms which can withstand long cry-preservation. New researches in biology return promising results. If the number density estimates based on the discovery of two ISOs are even approximately correct, there should be a number of ISO in the solar system at any one time. Future sky surveys should start finding a regular stream of 1I- type ISOs. 2I-type interstellar comets appear to be much rarer, and will probably be a decadal phenomena. A long term program to find and visit ISOs can start now with existing technology. Recently it is demonstrated that a mission to 1I/'Oumuamua would be feasible, even without Solar Oberth Maneuver, and could be used to explore ISOs. New technology and new instruments will be required to best find passing ISOs, and also crucial development of technology for safely embedding. We will disscuse chance of life samples to survive flight to other stellar system.
