Understanding Space Frontier Areas

Distant reaches of space loom as a strategic horizon. The vast majority of space operations have, so far, been limited to a few families of near-Earth orbits. However, space beyond geostationary Earth orbit, or xGEO, is likely to become important for strategic purposes in the near future. This is especially true of cislunar space, that region of space in which the gravity of Earth’s moon is significant. This paper refers to xGEO and cislunar space as Space Frontier Areas, since missions there have not yet reached sufficient scale to cluster into patterns of use.
