Question about the moon landing, explain something to me please

The lunar module's engine has a high expansion ratio of 43:1, so the exhaust gas at the nozzle exit is already low density. Since the Moon has no atmosphere, it rapidly expands a lot more once outside the engine, creating a very low-density plume. This low density means it can't push rocks and dust very hard.

The landing module touches down on solid rock, covered in a layer of fine lunar dust, so there is no reason why it would create a blast crater. Even if the ground were less solid, the amount of thrust being produced by the engines at the point of landing and take off is very low in comparison to a landing on Earth because of the relative lack of gravitational pull.

Dust was blasted out when they landed leaving bare rock,,the leg is in a small crater,dust settled immediately when the engine turned off and produced the foot print when the guy stepped off the lander.

WHAT "lunar dust"? All I see in that picture is a small hill of lunar regolith IN FRONT OF of ONE lunar landing pad. That picture is taken from a distance from the lunart lander. The Moon is a FOUR dimensional place (3 spatail dimensions and one relative temporal dimension). The Moon is NOT covered in feets to meters of of dust. The surface is composed of everything from bare solid rock to boulders to pebbles to clay sized particles and micro meteorite dust unevenly distgributed over the surface of the Moon. The landers LANDED ON PURPOSE where there was a solid foundation to support the landers not areas where there would be meters of dudt for the landers to sink into.

"...Bad: In the pictures taken of the lunar lander by the astronauts, the TV show continues, there is no blast crater. A rocket capable of landing on the Moon should have burned out a huge crater on the surface, yet there is nothing there.

Good: When someone driving a car pulls into a parking spot, do they do it at 100 kilometers per hour? Of course not. They slow down first, easing off the accelerator. The astronauts did the same thing. Sure, the rocket on the lander was capable of 10,000 pounds of thrust, but they had a throttle. They fired the rocket hard to deorbit and slow enough to land on the Moon, but they didn't need to thrust that hard as they approached the lunar surface; they throttled down to about 3000 pounds of thrust.
