Crater Studies: Crater Measurements
1967Abstract : Project Pre-Gondola I, a series of four 20-ton high explosive cratering detonations, was conducted by the U. S. Army Engineer Nuclear Cratering Group during October and November 1966 in order to determine the cratering characteristics of the Pre-Gondola project site located about 18 miles south of the town of Glasgow, Valley County, Montana.

Lonar Crater, India, a Meteorite Crater?
Meteoritics, 1964AbstractA recent field reconnaissance by one of us (ECL) has tended to support the view that the Lonar Crater, India, is probably a Quaternary meteorite crater. This origin is suggested by the high degree of circularity, the depth to diameter ratio, the breccia of crushed rock revealed by drilling, the quaquaversal dip of the surrounding country rock ...

Impacts of small celestial bodies, in terms of energy density, occupy the range between ordinary chemical high explosives and nuclear explosions. The high initial energy density of impact gives them some features of an explosion (shock waves, melting and vaporization, mechanical disruption of target rocks).

On Crater Verification Using Mislocalized Crater Regions
2017 IEEE Winter Conference on Applications of Computer Vision (WACV), 2017Automatic crater detection in planetary images is an important task with many applications in planetary science, spacecraft navigation, landing, and control. Typically, crater detection algorithms consist of two main steps: candidate crater region extraction and crater verification.

Secondary craters on Europa and implications for cratered surfaces
Nature, 2005For several decades, most planetary researchers have regarded the impact crater populations on solid-surfaced planets and smaller bodies as predominantly reflecting the direct ('primary') impacts of asteroids and comets. Estimates of the relative and absolute ages of geological units on these objects have been based on this assumption.

Meteoritics, 1966
Abstract Recent observational evidence emphasizes the importance of craters as a prominent surface characteristic of the smaller planetary bodies in the solar system. Craters of similar appearance may have very diverse origins. An initial assumption as to the type of origin should not influence an impartial and detailed physical study of any given ...

Martian cratering III: Theory of crater obliteration
Icarus, 1971Discussion of a theoretical basis for interpretation of Martian crater obliteration. Strong evidence is found that Martian craters are being degraded and obliterated at a rate much faster than on the moon, but much slower than on earth. The theory obviates the need to interpret the diameter distribution in terms of two classes of impacting bodies, as ...
