During the final metres of the powered descent of Apollo 11, astronauts Neil Armstrong and
Buzz Aldrin lost sight of the lunar surface. As the retro-rockets fired towards the lunar dust–or …

After landing in the Utopia Planitia, Tianwen-1 formed the deepest landing crater on Mars,
approximately 40 cm deep, exposing precious information about the mechanical properties …

Understanding plume impingement by retrorockets on the surface of the Moon is paramount
for safe lunar outpost design in NASA's planned return to the Moon for the Constellation …

The soil‐blowing phenomena observed in the Apollo lunar missions have not previously
been described in the literature in sufficient detail to elucidate the physical processes and to …

A novel, two-way coupled, dusty-gas flow model has been developed in the direct simulation
Monte Carlo (DSMC) framework and employed for the dust-dispersion study on lunar …

A recently proposed hyperbolic granular model (Balakrishnan and Bellan, 2024) has been
used to investigate the problem of supersonic-jet induced cratering on a solid-particle bed …

Understanding plume-surface interactions is essential to the design of lander modules and
potential bases on bodies such as the Moon, as it is important to predict erosion patterns on …

The present investigation focused on adapting and validating stereo-photogrammetry for
obtaining three-dimensional, time-resolved, nonintrusive, full-domain measurements of …

The impact of the drag model in the simulation of turbulent granular flows is studied using
databases here created through simulations of supersonic jet-induced cratering in granular …

A method of achieving a dimensionless collapse of erosion-rate data for cohesive sediments
is proposed and shown to work well for data collected in flume-erosion tests on mixtures of …
