Masten Space Systems and University of Central Florida are studying regolith cratering effects in different plume environments to understand cratering and landing pad durability. Testing is characterizing lunar surface ejecta particles (size, velocities, trajectories, and other geotechnical characteristics) ...

Define cratering charge. cratering charge synonyms, cratering charge pronunciation, cratering charge translation, English dictionary definition of cratering charge. A charge placed at an adequate depth to produce a crater. Dictionary of Military and Asso
The effects of the hypersonic atmospheric shock acting on the Venusian surface are considered in terms of induced maximum gas pressure, density, particle velocity, and temperature, for varying angles and velocities of impact. The maximum boulder size that can be saltated by the shock wave induced...
(e.g., CO2and H2O) in the crust also decreases the amount of melt produced as compared to craters formed in crystalline rocks (Kieffer and Simonds, 1980). The discovery of extensive evaporite materials, for example, in Meridiani Planum, suggests that these effects can be locally important on...
There is evidence that during 4.3-3.9 Ga the Earth experienced a period of intense bombardment similar to that recorded on the moon. From cratering mechanics and by comparison with more recent terrestrial impact structures the effects of... RAF Grieve - 《Precambrian Research》 ...
