My first public look at the Making History Expansion for Kerbal Space Program. The main feature is the mission builder component which adds a drag and drop scripting system to let players assemble a missions and campaigns to share. There are a bunch of new parts which match up to the early US & Soviet space programs, and the final version will include a story mode with prebuilt missions which I've been specifically ordered not to spoil at this time.
Making History will be released... soon.

If you want to use my hastily assembled mission it's available for download here:
