After the New Horizons flyby of Pluto it is time for an Solar System Exploration History update to version 1.3.12. I remodeled the info box for the Pluto system. (Scroll down to the Kuiper Belt. It's pretty far down.) Hovering over the images will enlarge it and highlight the respective object in the list and show additional details. Hovering over the list item also enlarges the object-image.
The images will be updated when the New Horizons mission will publish new or better pics. Kerberos and Styx will also get images eventually, I think.
