NASA Grand Tour Retro Poster

The Grand Tour is the route the Voyager 2 spacecraft took to visit all four outer planets. We imagined this would be something people might want to repeat, since it's a flight plan that's possible every 175 years or so, when the outer planets are arranged just right. In the future, it might be considered "quaint" to experience a gravity assist. 

Style-wise, the design came from some references we looked at from transparency overlays from the 1960s. It initially had a black background, but we inverted it and the design just clicked.
