In a Solar System full of interplanetary cruisers, ultra-powerful lasers, and dozens of independent colonies, it was recognized early on after the Great War that some sort of regulatory body would be needed to keep the peace, provide for safe passage, and most importantly, keep the Terra-watt level Navigation Lasers from being used as weapons. What emerged from these necessities was the Aerospace Transport Authority.
AsTrA is still in its infancy; chronically underfunded, the multi-national organization much more impressive in theory than in reality. Tasked with regulating interplanetary transit, AsTrA ostensibly has direct control of all Navigation Lasers in Terran and Martian orbit. In practice, however, AsTrA must rely on assistance from the polities that use the Lasers for transport. In order to prevent political or economic factors from overly influencing freedom of travel, delegations from all polities and organizations are assigned to each transport node so that they can police one another. Tensions run high in the outposts that house the Nav-Lasers, and many feel that unless AsTrA is given more funds, it is only a matter of time before personal conflicts in space spill over into conflicts among nations.
