Mon Dec 02 05:25:45 UTC 2024: ## Space Junk Crisis: Urgent Action Needed to Prevent Low Earth Orbit Collapse

**Geneva, December 2, 2024** – The rapid proliferation of satellites and space debris in low Earth orbit (LEO) poses a critical threat to global communication, navigation, and scientific exploration, according to experts and a recent United Nations panel. Over 14,000 satellites, including thousands of defunct ones, and an estimated 120 million pieces of debris currently clog LEO. This congestion is increasing at an alarming rate, with a 17% rise in close calls between satellites in the past year alone.

The UN panel, meeting in late October, stressed the urgent need for a comprehensive, internationally shared database of orbital objects and a robust framework for their management. Co-chair Aarti Holla-Maini highlighted the necessity of information sharing between public and private space operators to prevent collisions. The risk is substantial; a modeled scenario projects potential financial losses of $556 million over five years due to collisions.

The situation is exacerbated by incidents like the August explosion of a Chinese rocket stage and the June explosion of a defunct Russian satellite, both adding thousands of new debris fragments to LEO. The concentration of satellites in specific bands, such as those used by SpaceX’s Starlink internet service (6,764 satellites as of November 27th), further intensifies the risk. SpaceX alone reported performing nearly 50,000 collision-avoidance maneuvers in the first half of 2024.

While some nations are willing to share data, others are hesitant due to security concerns, particularly regarding dual-use satellites with defense applications. Commercial secrecy also presents a significant obstacle. The lack of a centralized system, coupled with geopolitical tensions, hinders effective coordination.

Experts emphasize the need for global cooperation, drawing parallels to air traffic management by the International Civil Aviation Organization. However, challenges remain, including building consensus and establishing trust among nations with varying levels of cooperation and data-sharing willingness. The UN panel will present its findings at a committee meeting next year, aiming to facilitate the development of enforceable global rules for space traffic management. The race against time to mitigate the growing crisis in LEO is now underway.
