History of the US Moon Base

As you know, we are approaching the twentieth anniversary of man's permanent habitation of the moon. Yes, ever since President Reagan insisted America implement a moon colony by 1990, astronauts have lived at Moon Base. This Nasa site chronicals the designs for a permanent moon habitat of the decades. Unfortunately, you can't zoom in on the pictures.

This is apparently part of a series designed for High School students to teach the history of space exploration. The top level page includes a history of the shuttle and discussion of a Mars mission.
