    Ok This is really two questions.
    Does it belong in the biology section? Probably not.

    1. Is it possible in a future scenario to send a craft into deep space that contains the crews DNA. Once they arrive at their distant planet. The ship clones them. Would this be plausible?

    2. Once the brain is fully understood is it possible that we could learn to "save" the memory/experiences in the brain and put the memory into the cloned people?

    Obviously the amount of technology and research that is needed to get to this point is probably centuries away.(if possible)


    This perhaps would bypass the daunting task of keeping a living civilization alive for that duration. Even a crew kept in a cryrogenic state would be difficult.

    Item 1 is certainly plausible and has been proposed often in the past.
    Item 2 is less certain, but I would not rule it out.

    The easier method is to freeze embryos.

    The problem is how you get from embryos to humans and not just any humans but ones capable of running a starship. If all you want is human colonists for a new world and are ok with them being kind of barbaric the process is simpler.

    Any system will require artificial wombs, and very, very sophisticated robots. So use them to thaw out and incubate embryos. Then let the robots raise those kids and teach them. All this would have to be done with David88's suggestion, anyway. So make it easier. Frozen embryos are an existing technique today. Much simpler than recombining DNA.

    The clones would have to be educated. This would not be difficult since the ship would have advanced computers etc. The problem I see is sending a fully automated ship you would still need some sort of crew to oversee the ship. It may even be possible to educate the clones in utero which would make things easier.
    Not all who wander are lost... Some of us just misplaced our destination.

    If the ship were fully automated why would you need a crew to oversee it? By definition, fully automated means that no crew would be necessary. We are presumably talking about a time when technology has advanced to the point that AIs are not only a reality, but highly sophisiticated. It is possible that when it comes time to raise children from the embryos or DNA constructs that the AIs would be embedded in humaniform robots. If this is not done the personalities raised in the absence of para-humans would be aberrant, at least by our standards.

    Thankyou for all the responses I absolutely agree with the embryo method rather than DNA (didn't think of that). This future craft could possibly do everything automated even dealing with entry into the atmosphere and landing. All the "crew" would have to do is start the new world.

    Not only could there be a human embryo bank but also animals, plants, and fungus as well.

    Is it possible that a planet that has similar factors to ours simply didn't form life?

    I wouldn't dismiss your original idea about creating the colonists from scratch. If you had technology capable of rearing humans by robot, it would be a safe bet to assume that we could also by that time take genome sequences and produce viable zygotes from them. Indeed, it's more or less (half-way, at least) been done already with bacteria.

    Using frozen embryos would seem to offer no real advantage to a civilisation technologically advanced enough to remotely colonise distant worlds. They'd be a liability, easily damaged and irreplaceable. Genomes, unlimited in number, perhaps even designed on arrival and tailored to the local environment, would be a better strategy.

    True keeping an embryo viable after all those thousands of years would be similar to the challenges of keeping a viable human being in a cryrogenic state.

    This may seem like a science fiction conversation now, but I believe it is important to start NOW. Human beings are capable of nearly anything, I firmly believe that. We need to get our act together here on Earth first before those kind of endeavors seriously.

    We(scientific minds and leaders) need to stop concentrating on this current generation so much(which is still the most important) and focus on the long term survival of our species and life itself.

    It may very well be that life is an extremely rare occurance so we need to preserve it.

    Stop fighting over superstitious beliefs and political ideologies would be a great start.

    However, the belief that we should expand beyond the Earth, take responsibility now for the species in a thousand or ten thousand years and have as an aim the spreading of life throughout the galaxy anywhere that is presently barren, is itself a political ideology. How are you going to get around that one?

    You are right it is itself a kind of ideology but it is the one that will ultimately preserve life in the future. I think that human kinds thinking has to change in order for this to ever happen. If we stoped looking at ourselves as Americans, Britsh, Russians, Iranian etc. and rather looked at ourselves as human being on this Earth who at any moment could be wiped out from a sleugh of multiple cataclysms. I'm not trying to democratize every country or suggesting we all have to have the same economic strategy. What I'm saying is that we need to at least try to expand into space, it is much more constructive than war. (This is all just my opinion for whatever its worth)
