Our memorabilia gallery serves multiple purposes. It provides historical context for our maps, in terms of chronology as well as precedence. It also provides a reference for people who don’t know much about space exploration, but want to get involved. The space pioneers I have highlighted are good candidates for names of additional planetary roads.

Imagine a sinuous sulcus of rover tracks on the Moon from the standpoint of Homo planetarius, an advanced human species, a million years from now. On the lunar surface, where no wind or atmosphere erases the past, they will stand as enduring relics - symbols of immortality. Much like the Mayan or Egyptian pyramids, they will whisper of the mystery and mastery of an ancient, space-faring civilization. Earth will be unrecognizable then, with most of our architectural structures demolished, but the planetary roads will remain unchanged. There will be only one system of lunar roads but many more lunar missions over the next 1000 millennia. How often do we get the opportunity to design and build something that will still be intact millennia later? These are the first roads in space.
