When was the U.S. flag first flown on the moon?

We landed on the moon and placed a flag there July 1969. By putting the flag there we were claiming that part of the moon for the United States. This tradition goes back centuries to the first explorers claiming lands for their country. Today, the flag is still on the moon and just as good as it was the day it was placed . On the moon there is no wind or rain to cause damage.
