Around the time NASA was studying the likes of space colonies and solar power satellites in the 1970’s, it was also commissioning studies of advanced launch vehicles which would be cheaper than the Shuttle (which as yet had not launched nor proven to be as massively expensive as it would turn out to be). One such design was a single stage to orbit vehicle designed by Martin Marietta. Similar to the Shuttle Orbiter in configuration, it was comparatively very fat due to being stuffed full of liquid hydrogen fuel and liquid oxygen. Diagrams have been floating around of this thing and are readily accessed; less rarely seen is color artwork of it.
