I have finally put my interactive timeline of Solar System Exploration History on GitHub as an open repository, including all data and graphics. Don't look at the code too closely though, it has grown over a very long time and that is how it looks, like a shrub. Well, making it accessible is at least one incentive to improve it.
I'll also put up some documentation in the readme and several overview graphics, such as the ground systems associated with spacecraft operations above. All of it is accessible viathe page on this blog and on my github.io site.
