How Do You Preserve History On The Moon? : NPR

Historic preservationists are hoping that the upcoming 50th anniversary of the Apollo 11 moon landing this summer will persuade the United Nations to do something to protect Neil Armstrong’s footprints in the lunar dust.

Some of his boot marks are still up there, after all, along with other precious artifacts from humanity’s first steps on another world. Armstrong and Buzz Aldrin left behind tools and science equipment, a plaque that read, “We came in peace for all mankind,” and the U.S. flag, which has likely been bleached white by five decades of harsh ultraviolet light.
