A plan for the development of lunar astronomy
AIP Conference Proceedings, 1990This is a report synthesizing discussions of the Astronomy/Astrophysics Definition Team at the Lunar Science Strategy Workshop for the Exploration and Development of the moon which was held at the NASA Johnson Space Center during August 15-16, 1989.

Introduction to the Techniques of Interferometry and Lunar Occultation in Radio Astronomy
Resonance, 2018Radio telescopes allow a 24 × 7 observation time window of those regions of the space which appear dark in the visible region. But, the major problem with a single radio telescope is its poor resolution. In this article, the method of interferometry in radio astronomy is discussed by citing the example of a two-element interferometer.

‘Out of a greate laborinth of errors’: Lunar astronomy in London before Kepler
Notes and Records: the Royal Society journal of the history of science, 2021Johannes Kepler is considered to be the first scholar to have offered an adequate description of heavenly phenomena observed on the Moon's sky. Kepler outlined his ideas in his Somnium (The Dream), written originally in 1609, and subsequently printed in ...

Engineering technologies for lunar-based astronomy
Advances in Space Research, 1994Abstract Planning is underway to return to the Moon and explore Mars. Scientific outposts on the Moon will conduct a variety of exploration and experimentation, including astronomical observations. For lunar-based astronomy, we propose a progression in capability over time from small automated telescopes to a 16-meter reflector.

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.

Lunar Radio Astronomy Observatory
1966Lunar Eadio Astronomy Observatory. Terrestrial, orbital and lunar environments are compared from the radio-astronomical point of view. The terrestrial environment is limited at long waves by the ionosphere, atmospheric noise and man-made interference. The centimeter and shorter waves are plagued by atmospheric absorption and radiation.
