A question I have not seen touched on, how many people do you send? You need to be genetically diverse and have a sustainable population for a colony, but you have limited space on the ship. Also, what about pets and livestock? Do you take Fido? Do you bring a herd of sheep for milk and wool? Even if you find a habitable planet, the chemistry of any plants or animals you find there may not be compatible with human needs.
