The essential systems required to send and establish life-support for Earth originating biological life is tediously laborious, and very expensive. It would make greater sense to perfect Android Robotic systems eliminating need for life support systems for the journey, and on Planet. These Pioneers would then perfect the essential systems and living environment to then cultivate from Human genetic material, a new colony of Humanity. The advantage to the Human born on the Planet negates the obvious affects of a changed environment on those originating from Earth. Too, the strong potential loss of human life on first, experimental landings is eliminated. <br><br>However, the one danger of adopting this approach: the Androids realizing they don't need a biological life form to corrupt its `Space'.
