Though humans haven’t been much further than the Moon, our unmanned spacecraft certainly have. This visualization displays the paths most of our spacecraft have taken in amongst and outside of the planets and moons of the Solar System.
The spacecraft data and planet orbital data is derived from NASA/JPL Horizons ephemeris. The image was rendered using a modified version of my Orbit Viewer WebGL application and put into infographic form using Photoshop. Body and spacecraft positions are as of December 15, 2013.
Originally intended as an animation, my browser was not too amused with the quantity of data being thrown at it. In the new year, given sufficient demand, I may optimize the modeling and animation algorithms and either produce the animation or release it as a distinct WebGL visualization.
