Space traffic surge as Earth's orbit faces satellite congestion crisis | – Times of India
Advertising
The increasing congestion in low Earth orbit (LEO) has become a growing concern for the future of space activities. With thousands of satellites already in orbit and millions of pieces of debris from past missions, the risk of collisions and the potential for creating hazardous conditions in space is escalating rapidly. As space exploration and commercial ventures continue to expand, the need for coordinated efforts and effective management of LEO has never been more critical. Experts warn that without international cooperation and robust regulatory frameworks, this vital region of space could become unusable, severely impacting global communication, navigation systems, and scientific progress.

Satellite surge and debris raise urgent space traffic coordination concerns
Currently, more than 14,000 satellites are in orbit around Earth, with roughly 3,500 of them inactive. Additionally, there are approximately 120 million pieces of debris from previous launches and collisions. This growing accumulation of objects in space has reached critical levels and is escalating at an alarming rate.
In late October, the United Nations’ panel on space traffic coordination issued an urgent call for the establishment of a shared database to track orbital objects. Aarti Holla-Maini, co-chair of the panel and director of the United Nations Office for Outer Space Affairs, emphasized that “there’s no time to lose” and that facilitating the sharing of information between satellite operators is essential to prevent collisions. LEO is vital for global communications, navigation, and scientific exploration, making its protection critical.
However, creating a centralized system for tracking and managing orbital objects presents numerous challenges. While some countries are open to sharing data, others are reluctant due to concerns over the security of dual-use satellites, which serve both military and civilian purposes. Additionally, many commercial companies are hesitant to disclose satellite data for fear of exposing proprietary information. This reluctance has resulted in informal methods being used to avoid collisions, which further complicates the situation.

Recent incidents highlight the growing risks in space
The risks associated with the growing congestion in LEO are becoming more evident. Recent incidents include a Chinese rocket stage explosion in August, which scattered debris in orbit, and a defunct Russian satellite that exploded in June, causing astronauts aboard the International Space Station (ISS) to take shelter for an hour. These events underscore the increasing hazards in space, as more and more satellites are launched, particularly with commercial ventures like SpaceX’s Starlink expanding rapidly.
Rising satellites increase collision risks and the need for space traffic regulation

Projections suggest that tens of thousands of additional satellites could enter orbit in the coming years, increasing the risk of collisions. The financial cost of such collisions could be significant, with estimates suggesting a potential $556 million risk over the next five years.
Industry leaders have stressed the need for immediate action to establish enforceable regulations similar to those used in air traffic management. The United Nations panel plans to present its findings at a committee meeting next year, underscoring the need for global cooperation to ensure the continued safety and sustainability of space activities as the human presence in LEO grows. As the situation intensifies, the urgency for a unified approach to managing space traffic and preventing further environmental degradation of LEO is more apparent than ever.
