Larry Kellog pointed me to an important document "NASA 1965 Summer Conference on Lunar Exploration and Science (NASA SP-88)". It is a document of 420 pages long, that talks about the Apollo Extension System (AES), the follow-up of the Apollo program with longer stay times, greater exploration capabilities for the 1970-1974 period. Unfortunately, the Apollo project stopped after Apollo 17. After a long period with no activity worth mentioning, there are again plans; plans for the moon, for Mars and, who knows, beyond. But it is interesting to read about what they were considering.

The document is a bit difficult to find, but you will at http://www.lpi.usra.edu/lunar_resources/documents.shtml it's at the bottom of the page.
