Request for Q4 update for planetary fx

When we land on planets we see that when the ship is few meters above the ground, before touching down, a lot of dust rises from the ground because of the engine thrust.

On low gravity planets I suggest that this dust remains suspended for few time (2-3 minutes) around the ship creating a layer of haze/fog.

Same for SRV, we already see the wheels lift up dust leaving a small dust cloud behind. This cloud should last longer on low gravity planets.

Without atmosphere, the dust would quickly fall back to the ground (just as quickly as rocks).

Yes, in fact rocks fall much slower on low-G planets. Dust is much lighter so the jet blast should send it much higher thank rocks with consequent longer time to fall back to the ground.

No, the dust will fall at exactly the same speed as the rocks, the higher it's blown off the ground the faster it will fall. The moment thrust is shut down the immediate area of the ship will be clear of dust, basic physics. A piece of dust a nanometre across will fall at the same speed as a rock weighing 1 ton. Surface dust blown away at an angle from the ships thrusters will follow a parabolic path away from the ship until it hits the ground. Sorry there will be no dust clouds hanging around the ship in an airless environment, this makes no sense in physics.
