Over the last several years NASA has run a really fun advertising campaign to promote the space program. Using a retro travel poster theme, they have released a series of posters imagining what it would be like to travel to other planets, but doing it in a way that assumes space travel is just as common as getting on a plane and flying across the country. There have also been posters promoting the achievements of the Voyager and Cassini space probes, some of which draw inspiration from 70's and 80's era music posters. Over twenty posters have been created so far and the best part of this campaign is that NASA has offered high resolution files of all the images for anyone to download, free of charge, and have them printed poster size.

All of the images can be found at the following sites...
