Space Situational Awareness and Conjunction Assessment: Knowing What Shares the Orbit

Fri, 29 May 2026 00:00:00 +0000

Orbit is large, but useful orbit is not empty. Working satellites, rocket bodies, fragments, deployment hardware, defunct spacecraft, and small debris all share a moving environment where speed gives even modest objects serious consequence. Space situational awareness is the practice of observing that environment, maintaining knowledge about objects in it, and helping operators decide when proximity becomes risk.

Space Debris and Orbital Traffic explains why debris is a long-term infrastructure problem. This guide focuses on the evidence layer behind day-to-day traffic decisions. A satellite operator cannot avoid an object merely because it exists. The operator needs to know where the object is likely to be, how certain that estimate is, whether the paths are meaningfully close, what a maneuver would cost, and whether moving one spacecraft creates other problems.
