Model Age Derivation of Large Martian Impact Craters, Using Automatic Crater Counting Methods

open access: yesEarth and Space Science, 2021
Determining when an impact crater formed is a complex and tedious task. However, this knowledge is crucial to understanding the geological history of planetary bodies and, more specifically, gives information on erosion rate measurements, meteorite ...

Morphological Features-Based Descriptive Index System for Lunar Impact Craters

open access: yesISPRS International Journal of Geo-Information, 2017
Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence ...

Magnetic Field Signatures of Intermediate-sized Impact Craters on Mars

open access: yesThe Astrophysical Journal, 2023
Magnetic field signatures over impact craters provide constraints for the history of the Martian dynamo. Due to limitations of the spatial resolution of magnetic field models, previous studies primarily focused on large impact craters (mostly ≥ 500 km in

Morphometric Analysis of Pluto’s Impact Craters

open access: yesRemote Sensing, 2021
The scope of this work is to carry out a morphometric analysis of Pluto’s impact craters. A global Pluto digital elevation model (DEM) with a resolution of 300 m/px, created from stereoscopic pairs obtained by the New Horizons Mission, was used to ...

Accurate Mapping and Evaluation of Small Impact Craters within the Lunar Landing Area

open access: yesRemote Sensing
Impact craters, as the most distinct lunar structural unit and geological structure, are marked on the Moon’s surface. For over a decade, researchers have focused on identifying and exploring large- to medium-sized impact craters on the surface of the ...

The missing large impact craters on Ceres. [PDF]

open access: yesNat Commun, 2016
Asteroids provide fundamental clues to the formation and evolution of planetesimals. Collisional models based on the depletion of the primordial main belt of asteroids predict 10–15 craters >400 km should have formed on Ceres, the largest object between ...

What Is a Polygonal Impact Crater? A Proposed Framework Toward Quantifying Crater Shapes

open access: yesEarth and Space Science, 2023
Impact craters are used for a wide array of investigations of planetary surfaces. A crater form that is somewhat rare, forming only ∼10% of impact craters, is the polygonal impact crater (or PIC).

Object-Oriented Remote Sensing Approaches for the Detection of Terrestrial Impact Craters as a Reconnaissance Survey

open access: yesRemote Sensing, 2023
The purpose of this study is to employ a remote sensing reconnaissance survey based on optimal segmentation parameters and an object-oriented random forest approach to the identification of possible terrestrial impact craters from the global 30-m ...

Impact crater degradation, Oxia Planum, Mars

open access: yesJournal of Maps, 2021
The main goal of the European Space Agency (ESA) and Roscosmos ExoMars rover mission is to collect samples from the near-subsurface of Mars. The rover will look for any physical or chemical evidence of ancient life in the near subsurface.
