The only possible soundtrack for a compilation of images from the New Horizons mission is obviously "Gosh" by Jamie XX. The brilliant original video for the track features a science fiction plot about terraforming Mars ( http://www.dailymotion.com/video/x2ollof_jamie-xx-gosh-official-music-video_music ). I adapted the video with public domain material from Nasa because it seemed like a natural fit. Also I had been listening a lot to the Jamie XX record around that time when the New Horizons spacecraft reached Pluto and sent all these images.
