Anyway, this is their blurb for the posters:
Imagination is our window into the future. At NASA/JPL we strive to be bold in advancing the edge of possibility so that someday, with the help of new generations of innovators and explorers, these visions of the future can become a reality. As you look through these images of imaginative travel destinations, remember that you can be an architect of the future.There are more posters after the jump, and a few more. as well as more information and larger size downloads, at the JPL link.
