Study on Impacts
Something for my research -
They found that with lower air pressures, there was a smaller plume of sand, and with higher pressures, the plumes were much larger. This happens because with higher pressures, the air and sand pressures 'mix' in a sort of way, leading to a more fluid like behavior which lessens the friction and causes a higher plume.
On planets with dust such as Mars, this kind of research is the difference between a successful probe landing, and a hundred-million dollar chunk of buried metal.
