There are widely dispersed lunar sites of interest for known and potential resources, selenology and observatories. Discriminating characteristics include certain geologic and topographic features, local mineralogy and petrology, solar illumination, view of Earth and the celestrial sphere, and soil engineering properties.
The designs and performances of lunar optical and submillimeter interferometer systems for the Space Exploration Initiative (SEI) are described. Attention is given to the conceptual design of these systems and to the concepts for the launch, transport, deployment, maintenance, and toleration of the lunar environment (both natural and induced by crew activity). Consideration is also given to the requirements for SEI resources (such as cargo space and crew time), the data return concepts, and the flight system technonogy develpment needs.

In addition, an extensive text is included which explains mission design methods, from launch window development to Saturn probe and orbiter arrival design, utilizing the graphical data in this volume as well as numerous equations elating various parameters. This is the first of a planned series of mission design documents which will apply to all planets and some other bodies in the solar system.
