Embryo space colonization
Embryo space colonization is a theoretical interstellar space colonization concept that involves sending a robotic mission to a habitable terrestrial planet, dwarf planet, minor planet or natural satellite transporting frozen early-stage human embryos or the technological or biological means to create human embryos. The proposal circumvents the most severe technological problems of other mainstream interstellar colonization concepts. In contrast to the sleeper ship proposal, it does not require the more technically challenging 'freezing' of fully developed humans (see cryonics). Various concepts Embryo space colonization concepts involve various concepts of delivering the embryos from Earth to an extrasolar planet around another star system. The most straightforward concept is to make use of embryo cryopreservation. Modern medicine has made it possible to store frozen embryos in various low-development stages (up to several weeks into the development of the embryo). The technologically more challenging but more flexible scenario calls for just carrying the biological means to create embryos, that is various samples of donated sperm and egg cells. Self replicating machines could spread out to interstellar space, bring uploaded human minds with them and/or receive them via radio or laser transmission and build artificial electronic brains/bodies as needed. The uploaded humans can raise
