Lunar regolith is called the material that covers the entire surface of our satellite and was formed from the impact of large and small meteorites. Because there is no wind on the Moon, the dust on its surface is not similar to sand, since it has suffered erosion and has a more rounded surface. Because there is no wind on the Moon, the dust on its surface is not similar to sand, since it has suffered erosion and has a more rounded surface. The lunar registry may come into contact with the eyes causing irritation or be inhaled causing damage to the respiratory tract and lungs; In addition to causing problems in the operation of the interior systems of the module.

In order to reduce the amount of regolith that emerges from the surface due to the movement of astronauts on it, the compaction of regolith particles is chosen.
Using a double roller steamroller
Due to the great weight that these machines have and to avoid over costs in their launch, both rollers are filled with cemented regolith.
Using a vibratory steamroller
With their low mass, they are easy to transport and several can be sent in the same launch.
The surface around the landing zone is covered with a protective tarp. It is not the best option, but it could be a quick and temporary or specific solution for certain areas.
Instead of trying to remove the regolith from the suit with brushes or vacuum cleaners, it is covered with a thin plastic cover that will be discarded when returning to the ship, which can be washed and reused.
Due to its weight, reuse and ease of transport, we think this is the best solution. Astronauts may be equipped with this protective suit / cover before doing an extravehicular activity and then take it off before re-entering the module. This can be washed or, if this is not possible, they will be discarded and another one will be used for the next EVA. It can be composed of Teflon, because it is capable of withstanding low and high temperatures.
Find a material that can withstand lunar hostility.
A Kennedy Space Center team devised a possible solution to this problem with an electrodynamic dust shield.
