Secondary craters on Europa and implications for cratered surfaces

Nature, 2005
For 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.

On Crater Verification Using Mislocalized Crater Regions

2017 IEEE Winter Conference on Applications of Computer Vision (WACV), 2017
Automatic 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.

Craters and Crater Springs of the Rio Salado

The Journal of Geology, 1948
The craters and the crater springs are located approximately 8 miles, air line, northwest of the Jemez Indian Pueblo, which is some 45 miles northwest of Albuquerque, New Mexico. They lie on the eastern slope of the valley of the Rio Salado, a tributary of the Rio Jemez, which, in turn, flows into the Rio Grande.

Crater Studies: Crater Measurements

1967
Abstract : 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.

The Crater

2019
To break the stalemate at Petersburg, a coal-mining engineer in a Pennsylvania regiment conceives a plan to tunnel under the Confederate works and plant a powerful mine that can blow a hole in the line for U.S. troops to exploit. The chosen assault troops are the Fourth Division of U.S. Colored Troops-trained to attack around the resulting bomb crater.

Lonar Crater, India, a Meteorite Crater?

Meteoritics, 1964
AbstractA 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 ...

Palaeomagnetism of the Vredefort meteorite crater and implications for craters on Mars

Nature, 2005
Magnetic surveys of the martian surface have revealed significantly lower magnetic field intensities over the gigantic impact craters Hellas and Argyre than over surrounding regions. The reduced fields are commonly attributed to pressure demagnetization caused by shock waves generated during meteorite impact, in the absence of a significant ambient ...
