Man has and always will have an intrinsic desire to explore. The seas and wilderness were once vast and infinate until they were conqured. It just took the proper ships, navigation equipment, desire etc. to make this possible. I realize that the earth is much smaller that outer space, but I believe we already posses the desire and the rest will follow with time. A proper understanding of the enigma of physics and protection/propultion in conjunction with it is all that is left unfound. Taking pictures is a great start. Maps are meant to be interpreted and expanded upon.
