Space Traffic Management: An Emerging Challenge

With increasing reliance on space-based technologies, active satellites in orbit have grown tremendously over the past few decades. As of early 2022, there are over 5,000 active satellites circling the Earth with thousands more anticipated to be launched in the coming years. However, this rapid growth in the number of objects in space has also increased the risk of collisions between satellites and space debris. Even a small piece of debris can damage a satellite and create more orbital clutter. Recognizing the need for enhanced monitoring and prevention of collisions, nations and commercial providers are emphasizing the importance of space traffic management through greater cooperation.

Tracking and Cataloguing Orbital Objects

A Space Situational Awareness (SSA) traffic management is comprehensive tracking and cataloguing of all orbital objects. Currently, the US Space Surveillance Network is the most advanced system, regularly monitoring over 27,000 objects 10 cm or larger in size. However, many smaller fragments less than 10 cm exist but are difficult to accurately track.

The US shares basic orbital data on these objects with other nations and agencies through the Space-Track.org website. Meanwhile, countries like Russia, China, France, Germany and Japan are also developing independent SSA capabilities. Greater data sharing and integration of these national SSA networks will help develop a more complete global catalogue.
