In total 63 different sites are known to exist. Of these, Tranquility Base, the site where the first human stepped onto another celestial body outside Earth, is of global and universal value to the history of humanity. Preservation conditions on the Lunar surface are so unique that in the absence of an atmosphere of note, even the boot prints of the astronauts and the tracks left by the rovers are preserved. Unless they are struck by micro- meteorites, or obliterated by subsequent visitation, they will remain visible in perpetuity. This paper discusses the extent, nature, significance and ownership of the space heritage sites on the Lunar surface. The sites are finite and unrenewable, and any modification of the sites, incl. visitation by humans or robotic rovers will impair a site’s integrity. Even unintentional spacecraft crash sites (due to orbital decay for example) retain significance to the scientific community and access to the sites needs to be managed wisely. In the absence of territorial, jurisdictional control over the Lunar surface, multi-lateral mechanisms need to be developed to ensure that humanity’s unique heritage on the Moon is not diminished or destroyed for short term gain. The key recommendations are: 1. The provisions of the Google Lunar X Prize be modified to exclude visitation of Lunar sites of cultural heritage, voiding any entry that does so. 2. A Register of Lunar Heritage Sites should be established. 3. The condition of Lunar heritage sites should be regularly monitored using orbital photography. 4. A global heritage convention governing the protection of space heritage should be put in place. 5. A multi-national technical advisory committee, ideally under the auspices of UNESCO, should evaluate pro- posals affecting space heritage sites on the Moon and other planetary bodies. 1.
