we cast our eyes up to our closest celestial neighbor and the only other world man has set foot on; the moon. We meet the last man to have walked the lunar surface, Captain Gene Cernan, who reveals how his experience was almost spiritual and how space exploration can unite us in a way that nothing else can. We then travel to the European Space Agency to see how they are leading efforts to put man back on the moon once again and we get hands on with the robots, rovers and 3D printed habitat that would form a lunar colony.
