[Non RPE] Visions of the future

NASA’s Jet Propulsion Labs has published  for free usage a number of retro styled travel posters for space travel: http://www.jpl.nasa.gov/visions-of-the-future/

Not only the images are amazing but the story for each of them could easily be the seed of wonderful Sci-Fi novels  “Astonishing geology and the potential to host the conditions for simple life make Jupiter’s moon Europa a fascinating destination for future exploration”
