Louis Friedman, author of Human Spaceflight From Mars to the Stars, has said, "Human space exploration will continue well into the future. It will be exciting, focused on the exploration and settlement of Mars." The scientists at NASA's Jet Propulsion Laboratory have spent many decades investigating our planets and the universe beyond and as a result have created some fantastic, imaginative travel destination posters bringing the idea of interplanetary travel to reality. Each page of Travel Posters of the Future 2018 Wall Calendar features a poster with a vision of the future that one day might just be a part of our brave new world.
