Fifty years ago, in 1970, a lunar crater was named in honor of Avicenna, one of the most influential physicians of the Medieval period. His encyclopedic work, The Canon of Medicine, attempted to codify all medical knowledge including dermatology. This contribution provides a brief overview of Avicenna, his contributions to medicine and dermatology, and

Proceeding of the 2011 IEEE International Conference on Space Science and Communication (IconSpace), 2011
This project focuses on identification of craters in terms of its characteristics and detection of these visual features of the moon to determine a safe landing site for a lunar Lander. Cheng et al. proposed using craters as landmarks for navigation purposes because this geometric model grants a robust detection under different lighting conditions ...

Abstract The form of the lunar impact crater size-frequency distribution is discussed. Latest results on the lunar cratering chronology in the first 1.5 Ga after its formation are reviewed. It is shown that most cratering arguments speak against an extraordinary high flux increase (‘cataclysm’) at ca. 4 Ga ago.

Recognition thresholds for lunar crater size were determined, analytically, for various look angles and magnifications, at an orbital altitude of 80 nautical miles. Elliptical image measurements for various sized craters were combined with some previous threshold recognition data for the ellipse (Casperson, 1950).

Abstract Measurement of crater circularity for 487 craters has shown that there are at least two populations of craters, the circularity of which appears to decrease with increasing age. Central peak formation is not confined to either population, but the subcircular population appears to be located preferentially around the circular maria.

Abstract This article traces the story of three amateur astronomers who created relief models to help them depict the changing illumination of certain lunar craters, examples of which can be found in UK museum collections today. English chemist Henry Blunt (1806–1853) adopted the emerging technology of electrotyping to reproduce and distribute his ...

The Moon, 1975
A review is presented of four hypotheses concerning the origin of lunar craters, taking into account the bubble hypothesis, the tide hypothesis, the volcanic hypothesis, and the impact hypothesis. A description is given of a series of experiments on impact craters and studies of a meteorite crater in Arizona are considered.

ABSTRACT An abridged reprint of a popular work by Holden which appeared in The Californian in 1892. Holden describes in a popular way the state of the art of lunar observation and science with a concentration on Copernicus and the Copernican ray system. Of substantially historical interest (Copernicus is thought to be of volcanic origin,

An analysis has been made of the tendency of large lunar craters to lie along circles. A catalog of the craters at least 50 km in diameter was prepared first, noting position, diameter, rim sharpness and completion, nature of underlying surface, and geological age.
