The Exoplanet Exploration Progam at NASA/JPL has commissioned a set of absolutely gorgeous posters for significant planets, moons, exoplanets, and nearby stars, each accompanied by text explaining their significance and what humans might do if we reach them.
The posters are available as hi-rez downloads, and since they're US government productions, they're copyright free and can be shared, printed, remixed, etc.
NASA's Voyager mission took advantage of a once-every-175-year alignment of the outer planets for a grand tour of the solar system. The twin spacecraft revealed details about Jupiter, Saturn, Uranus and Neptune – using each planet's gravity to send them on to the next destination. Voyager set the stage for such ambitious orbiter missions as Galileo to Jupiter and Cassini to Saturn. Today both Voyager spacecraft continue to return valuable science from the far reaches of our solar system.
