Projectile Velocity and Crater Formation in Water

International Scholastic Journal of Science, 2010
The relationship between the velocity of impact and maximum crater diameter was found for two steel balls dropped into water using 300 fps video. The maximum diameter of the crater was found to be proportional to the impact velocity and independent of ...

Impact cratering experiments into highly porous bodies [PDF]

, 2011
Asteroids represent both an opportunity and a risk. Their pristine environment captures the early collision evolution of the solar system; while their inherent ground impact potential could result in the mass extinction of life.

Chicxulub central crater structure: Initial results from physical property measurements and combined velocity and gravity modeling

, 2004
The Chicxulub crater in Mexico is a nearly pristine example of a large impact crater. Its slow burial has left the central impact basin intact, within which there is an apparently uneroded topographic peak ring.

Microbial Life in Impact Craters [PDF]

Current Issues in Molecular Biology, 2020
Asteroid and comet impacts are known to have caused profound disruption to multicellular life, yet their influence on habitats for microorganisms, which comprise the majority of Earth's biomass, is less well understood. Of particular interest are geological changes in the target lithology at and near the point of impact that can persist for billions of

Full waveform tomographic images of the peak ring at the Chicxulub impact crater [PDF]

, 2011
17/06/013 PDF version attached, OK to pub.Peak rings are a feature of large impact craters on the terrestrial planets and are generally believed to be formed from deeply buried rocks that are uplifted during crater formation.

Particle size distributions inside and around the artificial crater produced by the Hayabusa2 impact experiment on Ryugu

Earth, Planets and Space, 2022
Japanese Hayabusa2 spacecraft has successfully carried out an impact experiment using a small carry-on impactor (SCI) on an asteroid (162173) Ryugu. We examine the size distribution of particles inside and outside an artificial impact crater (the SCI ...

Polygonal impact craters on Ganymede

Meteoritics & Planetary Science, 2023
AbstractPolygonal impact craters (PICs) are unique geological features observed on various planetary bodies and constitute a small percentage of the impact crater population. This study focuses on PICs on Ganymede, where no such craters have been investigated so far. Here we present the distribution of PICs, examine their morphological characteristics,

Geology of the Selk crater region on Titan from Cassini VIMS observations [PDF]

, 2010
International audienceObservations of Titan obtained by the Cassini Visual and Infrared Mapping Spectrometer (VIMS) have revealed Selk crater, a geologically young, bright-rimmed, impact crater located similar to 800 km north-northwest of the Huygens ...

Sequence of infilling events in Gale crater, Mars: Results from morphology, stratigraphy, and mineralogy [PDF]

, 2013
Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine their origin.

The self‐secondary crater population of the Hokusai crater on Mercury

Geophysical Research Letters, 2016
Whether or not self‐secondaries dominate small crater populations on continuous ejecta deposits and floors of fresh impact craters has long been a controversy. This issue potentially affects the age determination technique using crater statistics.
