As you know, our Moon doesn’t really have much in the way of an atmosphere, but what you may not realize is that this has some very interesting implications. Namely, things don’t erode very easily, so the footprints left by US astronauts in the ’60s and ’70s are still preserved, and should be for a long time. This unique situation has given a brand new thing for people to worry about, and US lawmakers spent time that they were getting paid for in an attempt to legislate the issue. You see, some people are worried that, with commercial organizations getting into space flight and other countries working towards landing on the Moon, that we needed to make sure no one messes with our historical imprint. For this reason, lawmakers tried to pass a bill making the Moon landing site a national park. This failed, though NASA has asked people to at least attempt to respect the original lunar landing site, should they somehow end up there.
