On July 20, 1969, Neil Armstrong stepped onto the lunar soil, saying, "That's one small step for a man, one giant leap for mankind." Since the Moon doesn't have any wind or rain, the footprints should still be relatively untouched. NASA put in a lot of effort to make sure these footprints stay protected, as well as the location of the initial Moon landing. There are many flags on the surface of the Moon, too. But the flags left there are most likely discolored now because of the exposure to strong solar radiation.
