This illustration shows a semi-permanent lunar base, a six-person shelter landed by a direct flight from Earth and coupled to an expandable laboratory in the foreground. It's part of a 1969 Science Journal article about lunar colonies of the future.
The article's author, Dr. Rodney Wendell Johnson, was the Advanced Planner for NASA's Advanced Manned Mission Program Office. The illustrations by Roy G. Scarfo that accompany the article are pretty amazing.
Early lunar bases would grow from Apollo hardware. The picture [above], depicts Apollo lunar modules; that in the background carries a shelter and the other has landed a one man roving vehicle with a range of 8 km. This system would permit 14 day scientific missions in 1971-72, including geological drilling to about 35 m.
