Humans should not be going to the moon at this point in time for exploration. We should focus on robots going to the moon - spending that money on developing robots will have a much larger benefit than spending the money trying to keep a human safe. We'll develop advanced controlling and communication systems for this.<p>You can send a robot to the moon and leave him there - a human has to come back. That's an uneccessary expense.<p>When we have enough robots on the moon they can build the structures neccessary to support human life there.
