The footsteps last permanently on the surface of the moon until an object comes in contact with them.
In case you were curious, the reason why the footsteps will last so long is because the moon does not have an atmosphere interacting with the surface.
Yes, the footsteps are likely still there. There is no rain, wind nor any weather on the moon to disturb the footprints of Armstrong and the eleven other men who have walked on the moon. The only thing which would disturb the footsteps is objects (spacecraft, meteoroids, etc.) which impact the lunar surface. Given the area of the lunar surface and the fact that the footsteps are on the side of the moon facing the Earth, this is unlikely.
Footsteps on the moon will stay visible for a very long time, possibly for millions of years. This is because there is no wind or water on the moon to disturb the surface and erase the footprints. The lack of atmosphere means that there is no erosion process like on Earth.
no winds
it has no atmosphere to smooth out temperatures, and each day and night lasts a fortnight

No, the moon is very real. The footsteps of Neil Armstrong, the first man to step foot on the moon, are on the moon.
Yes
The first footsteps on the Moon remain because the lunar environment lacks significant weathering processes. There is no atmosphere, wind, or water to erode the surface, and the Moon's low gravity means that footprints, created in the fine lunar regolith, are not disturbed easily. Additionally, the lack of biological activity means that the marks made by astronauts in 1969 have been preserved for decades.
If I'm interpreting your question correctly, there are three phases like that. First is the waning gibbous, which comes after the full moon and lasts until the last quarter, also known as the half moon. That's the second one, the last quarter, and the third is the waning crescent, which lasts from the half moon to the new moon.
On July 20, 1969, Apollo 11 astronauts Neil Armstrong and Edwin E. "Buzz" Aldrin, the first men to land on the moon, plant the U.S. flag on the lunar surface.
Yes, because the moon doesn't have a strong enough atmosphere to support weather.
Due to the Moon's low gravity, it cannot hold in an atmosphere, meaning it cannot have weather. This means erosion cannot occur, making craters, footsteps, etc. never disappear. It also means it cannot rain at all on the Moon.
