American flags placed on the moon are now white
Lacarruba’s New Jersey company, Annin, made the nylon flags for $5.50 ($33 in 2012 dollars) a piece in 1969.
While the $5.50 nylon flags are still waving on the windless orb, they are not flags of the United States of America anymore. All Moon are now completely white.
For forty-odd years, the flags have been exposed to the full fury of the Moon’s environment – alternating 14 days of searing sunlight and 100° C heat with 14 days of numbing-cold -150° C darkness. But even more damaging is the intense ultraviolet (UV) radiation from the pure unfiltered sunlight on the cloth (modal) from which the Apollo flags were made. Even on Earth, the colors of a cloth flag flown in bright sunlight for many years will eventually fade and need to be replaced. So it is likely that these symbols of American achievement have been rendered blank, bleached white by the UV radiation of unfiltered sunlight on the lunar surface. Some of them may even have begun to physically disintegrate under the intense flux.
Also, according to the reports, all of flags are still standing up except the one left by Armstrong and Aldrin, the first two men on the Moon. The Apollo 11 lunar module crew placed the flag too close to their spacecraft and, according to Buzz Aldrin himself, it was blown away as they blasted off.
