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 May, 1969 issue of Science Journal features an article by Dr. Rodney Wendell Johnson about lunar colonies of the future. Dr. 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.
