Evaluation of Geomorphological Evidences for Possible Impact Crater of Zirouki in Sistan and Baluchestan, SE Iran [PDF]
مخاطرات محیط طبیعی, 2014 Despite the extensive studies on geomorphological phenomena in Iran, since investigation of meteorite impact craters h not been considered. Based on both remote sensing technique and field work we have recognized the circular structure of Zirouki crater ...

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.

The Morphometry of Impact Craters on Bennu [PDF]
Geophysical Research Letters, 2020 AbstractBennu is an ~500‐m‐diameter rubble‐pile asteroid that is the target of detailed study by the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS‐REx) mission. Here we use data from the OSIRIS‐REx Laser Altimeter to assess depth‐to‐diameter ratios (d/D) of 108 impact craters larger than 10 m in ...

The chemical composition of impact craters on Titan [PDF]
, 2020 We investigate the spectral behavior of nine Titan impact craters in order to constrain their surface composition using Visual and Infrared Mapping Spectrometer (VIMS) data and a radiative transfer code (RT) [e.g. 1] in addition to emissivity data.

Experimental Investigation of the Crater Caused by Hypervelocity Rod Projectile Impacting on Rocks
Shock and Vibration, 2020 To investigate the cratering effects of hypervelocity rod projectile impacting on rocks, a two-stage light gas gun was used to carry out 10 groups of small-scale experiments, whose velocity ranges from 1.5 km/s to 4.1 km/s.

An artificial impact on the asteroid (162173) Ryugu formed a crater in the gravity-dominated regime
Science, 2020 Blowing a crater in asteroid Ryugu The Hayabusa2 spacecraft was designed to collect samples from the nearby asteroid (162173) Ryugu and return them to Earth for laboratory analysis. Arakawa et al. describe how the spacecraft's Small Carry-on Impactor was

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 ...
