Cohesive properties of ice powders analogous to fresh plume deposits on Enceladus and Europa
Résumé
Ice powders are characterised by a custom rotating drum at very low temperatures. • Ice powder cohesion increases with the temperature over the range of 90 to 150 K. • A mechanical model allows to estimate the grains surface energy from flow behaviour. • Icy moons' regolith could see drastic cohesion change with diurnal cycles/location.
