A Lunar-Base Lab for Geology or Astronomy Courses
Journal of Geoscience Education, 1997 Based on long-term economic and technological trends, it is likely that lunar bases and related space activities will be a prominent feature of the early 21st century. The lunar-base lab featured here uniquely introduces students to the key elements of lunar geology by immersing them in the excitement of planning humanity's future on the Moon. Five (or

Structural Concepts for Lunar-Based Astronomy
Applied Mechanics Reviews, 1993Lunar-based astronomy requires structures that provide the required stiffness, strength, and dimensional stability in the challenging lunar vacuum, thermal, radiation, micrometeorite, secondary ejecta, and dust environments. Materials used in the structures must be durable to provide extended service life.

Space exploration and science go hand in hand. This is true for both robotic and manned missions. The advantage of missions that include astronauts is that they may be able to figure out how to repair something that stopped working, and they can modify the research itinerary if something unexpected of greater scientific interest is found.

The development and transmission of 248-day schemes for lunar motion in ancient astronomy
Archive for History of Exact Sciences, 1983Babylonian, Greek and Indian texts concerning the mathematical approximation of the periodically varying speed of the lunar motion are systematized and interpreted. Predicting lunar motion was essentially a problem of approximating a periodic zigzag deviation table at a quadratic level. The Babylonians applied arithmetical reasoning.

A synthesis arrary for lunar submillimeter astronomy
AIP Conference Proceedings, 1990This paper describes a system concept for a Synthsis Array for Lunar Submillimeter Astronomy (SALSA). It includes a brief discussion of the science objectives and the advantages of placing such an array on the moon, the system concept, and a top‐level discussion of the various subsystems, including the technology drivers associated with each.

ESA lunar study: Precursor astronomy missions to the Moon
Advances in Space Research, 1996Abstract We give a summary of the areas identified by the ESA Lunar Study Steering Group for Scientific Exploration of the Moon in the ESA report “Mission to the Moon”. We discuss the possible phased approach for different scientific areas and some potential Precursor Astronomy Missions. We give a short status of current related ESA studies.
