You should ask SpaceX if you can print their retro space tourism posters from last year as well. You know... where these NASA artists probably got the idea from

  As that article mentions, JPL's exoplanet tourism posters preceded SpaceX's posters: http://planetquest.jpl.nasa.gov/exoplanet_travel_bureau http://planetquest.jpl.nasa.gov/exoplanet_travel_bureau In any case, no need to ask SpaceX, the posters were released into the public domain.
