- Abstract:
- Outer space has long been characterized as “contested, congested, and competitive.” More than four thousand eight hundred active satellites currently orbit Earth, representing over forty nations, and nearly twenty-five thousand satellites are projected to join by 2030. Moreover, spacefaring entities are testing the limits of space exploration: Visionary space companies are aiming to launch space tourism programs and send humans to space within the decade, and governments and militaries are increasing activity in cislunar space—the sphere formed by the Earth-Moon radius—to leverage advantageous orbital regions. As humanity expands its frontiers deeper into the galaxy, the threats to US and allied space capabilities will continue to increase. Yet, despite the proliferation of space activity, the ability of international and national bodies to track and regulate space objects—often referred to as space traffic management (STM)—reflects a past era wherein few actors conducted limited operations in space. The current state of STM can be more aptly described as space situational awareness (SSA), or the mere knowledge of objects in orbit. Global actors (including national governments, corporations, and international organizations) track space objects and notify satellite operators when the probability of collision is notable. While collision avoidance maneuvers are standard when there is a one in ten thousand chance of collision, it is ultimately up to the operators to determine whether and when they will move. The limits of this decentralized approach to SSA were illustrated in September 2019 when a European Space Agency satellite veered off path to avoid a Starlink satellite whose operator missed an email notification signaling a high probability of collision.
