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.

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
