What does the flag on the moon look like now?

Answer 1

The flags were nothing special, they were purchased from a local department store shortly before launch. While we have no way, right now, to see the flags directly, we can make assumptions on their appearance by what we know of how things work on Earth.

On Earth, items left in the sun for long periods of time tend to bleach. This happens even though sunlight is filtered through the atmosphere here on Earth's surface. On the moon, no such filtering exists and the sunlight is much harsher. Since the flags have been up for nearly 5 decades, much of that time spent in unfiltered, direct sunlight, it's safe to assume the flags are very brittle and faded almost to the point of being unrecognizable. They likely appear to be white sheets of frayed cloth on a pole.
