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

Morphometric Analysis of Pluto’s Impact Craters
Remote 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 ...

Morphological Features-Based Descriptive Index System for Lunar Impact Craters
ISPRS 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 ...

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,

A BAYESIAN NETWORK FRAMEWORK FOR AUTOMATIC DETECTION OF LUNAR IMPACT CRATERS BASED ON OPTICAL IMAGES AND DEM DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Impact craters are among the most noticeable geo-morphological features on the planetary surface and yield significant information on terrain evolution and the history of the solar system.

A Machine Learning Approach to Crater Classification from Topographic Data
Remote Sensing, 2019 Craters contain important information on geological history and have been widely used for dating absolute age and reconstructing impact history. The impact process results in a lot of ejected fragments and these fragments may form secondary craters ...

Holocene impact craters on Earth
Miscellanea Geographica: Regional Studies on Development, 2023 Impact craters are formed by collisions of cosmic bodies moving with hypervelocity. The formation of these features is not restricted to the distant geological past; new structures are constantly being created and at least 13 confirmed impact craters and

Lunar Evolution Analysis Based on Numerical Simulations of Typical Lunar Impact Craters
Space: Science & Technology, 2023 Impact craters are one of the most important landforms on the lunar surface, playing a crucial role in the formation and later evolution of the Moon. For example, as a primary source of remote sensing observations and lunar samples, lunar regolith is ...

Impact cratering and the Oort Cloud [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We calculate the expected flux profile of comets into the planetary system from the Oort cloud arising from Galactic tides and encounters with molecular clouds. We find that both periodic and sporadic bombardment episodes, with amplitudes an order of magnitude above background, occur on characteristic timescales ~25-35 Myr.
