Will The Footprints On The Moon Disappear? (No)
Footprints on the moon will not disappear. There is no atmosphere on the moon, and the heat capacity and thermal conductivity of the surface material are very low, which makes the temperature difference between day and night on the moon large. During the day, the temperature of the moon's surface can reach 127°C when the sun shines directly on it, and it drops to -183°C at night. Since the rocks on the moon are decomposed by the high temperature, but it has no effect on the dust, the footprints on the moon will not disappear like the footprints on the earth, but will be preserved for a long time.
Driving on the Moon
China's Yutu-2 lunar rover left obvious traces of ruts on the moon, which were clearly recorded by the Chang'e-4 lander. Apollo 11 astronaut Armstrong also left the first human footprint on the moon, which has been preserved on the moon. There is no water or air on the moon. Even if there is water, it may be frozen in the dark area, and the surface will not be disturbed by wind and water. There are no signs of volcanic activity on the moon, nor have there been major earthquakes. Therefore, the geological structure of the moon generally does not change.
Long time
Scientists estimate that the traces left by humans on the moon will remain for a long time, possibly 1 to 2 million years, which is a very long time. But some events may change, such as the solar wind, a stream of high-energy particles ejected from the sun into space. Since the moon's magnetic field is only 1% of the earth's, the solar wind is likely to directly reach the moon's surface, thus changing the moon's appearance.
Meteorites
Another thing that has a great impact on the moon is meteorites. There are many craters on the moon's surface, all of which were formed by the impact of small celestial bodies in the solar system, which significantly changed the moon's appearance. Until now, there are still meteorites hitting the moon. If a meteorite happens to hit a human footprint, the human footprint will naturally disappear.
