Space Safety at Risk: Satellite Operators Urge International Cooperation

Sydney,Australia – Concerns are growing among satellite operators worldwide regarding the increasing risk of collisions and interference in orbit,prompting calls for greater international cooperation and data sharing. At the International Astronautical Congress, representatives from leading space companies highlighted the urgent need for improved coordination to ensure the long-term sustainability of space activities.

A key issue identified was the lack of interaction between satellite operators, particularly those launching new constellations. David Goldman, Vice President of Satellite Policy at SpaceX, emphasized the critical importance of sharing orbital data, known as ephemerides, stating that it is “the single most important thing you can do to help decrease risk in space.” While SpaceX and Amazon maintain close communication and coordination, especially during launches of Amazon’s project Kuiper satellites through Starlink’s orbital areas, this level of collaboration isn’t global.

Amazon officials echoed this sentiment, noting that a significant portion of operational satellites – estimated at 1,500 – pass through Kuiper orbits, yet contact data is only available for roughly half. “That’s really not a very safe surroundings,” asserted Josef Koller, Amazon’s Head of Space Safety and Sustainability. “It seems like such a simple thing to do to share your contact information…but that is the most critical item today.”

The challenge isn’t limited to Western companies. Peng Zhang, General Manager of GalaxySpace, a Chinese satellite operator, explained that while frequency coordination is readily available, communication regarding satellite operational details is often lacking.

To address this,industry leaders are looking to the International Telecommunication Union (ITU) as a potential facilitator. The ITU is slated to host it’s second Space Sustainability Forum next week in Geneva, with improved communication protocols as a primary topic. Jorge Ciccorossi,Head of the Space Strategy and Sustainability Division of the ITU Radiocommunication Bureau,outlined plans to coordinate the exchange of direct points of contact among key Low Earth Orbit (LEO) operators. The ITU also aims to establish a publicly accessible database of operator contact information to streamline communication and address issues like radio-frequency interference.

While consensus exists regarding the urgent need for improved communication, opinions diverged on further regulatory steps. Some advocated for a “code of conduct” for satellite operators, while others, like SpaceX’s Goldman, cautioned against hastily implemented regulations. He argued that the regulatory cycle is too slow to keep pace with the rapid evolution of the space environment and emphasized the ITU’s potential to act as a nimble facilitator of communication. “Having the ITU serve as a facilitator… is the single best thing that we can do to lower the risk,” he stated.

The call for increased transparency and coordination underscores a growing realization that proactive measures are essential to maintaining a safe and sustainable space environment for all.

How can the ITU leverage its existing frequency coordination expertise to enhance broader space traffic management?

The Growing Congestion in Orbit & Increased Collision Risk

The Earth’s orbital space is becoming increasingly crowded. The proliferation of satellite constellations – driven by demand for broadband internet, Earth observation, and other space-based services – is leading to a significant rise in the risk of space debris collisions. This isn’t a hypothetical problem; the potential for cascading collisions (the Kessler Syndrome) threatens the long-term sustainability of space activities. Space situational awareness (SSA) is paramount, but increasingly complex.

Operators are proactively seeking solutions, and a central theme emerging is the need for stronger international coordination, specifically through the International Telecommunication Union (ITU).

Why the ITU is Central to space Safety Coordination

the ITU, a specialized agency of the United Nations, already plays a crucial role in allocating satellite frequencies and registering satellite orbital slots. However, operators argue that its role needs to expand to encompass broader space traffic management (STM). Here’s why:

* Global Framework: The ITU provides a neutral, international platform for all spacefaring nations and commercial operators.

* Frequency Coordination: Preventing interference between satellites is vital, and the ITU’s existing expertise in frequency allocation is a strong foundation for broader coordination.

* Orbital Slot Registration: While currently focused on preventing interference, this registration process could be enhanced to include more detailed information about satellite maneuvers and end-of-life plans.

* Standardization: The ITU can facilitate the development of common standards for data sharing, collision avoidance, and responsible space operations.

Specific requests from Satellite Operators

Satellite operators aren’t simply asking for more regulation; they’re proposing a collaborative approach.Key requests include:

1. Enhanced Data Sharing: A centralized platform, facilitated by the ITU, for sharing orbital data, maneuver plans, and conjunction assessments. This would improve the accuracy and timeliness of collision warnings.
2. Best Practices for Deorbiting: Establishing standardized guidelines for safely deorbiting satellites at the end of their operational life. This includes defining acceptable deorbit altitudes and timelines. The current 25-year rule is seen by many as insufficient.
3. Improved Conjunction Assessment: Refining the process of predicting close approaches between satellites and debris. This requires better tracking data and more sophisticated modeling. Space debris tracking is a critical component.
4. Automated Collision Avoidance Systems: Encouraging the development and adoption of automated systems that can autonomously maneuver satellites to avoid collisions.
5. Spectrum Management for SSA: Allocating sufficient radio frequency spectrum for space surveillance and tracking activities.

The Role of Space Situational Awareness (SSA) Providers

While the ITU can provide a coordinating framework, the actual work of tracking and assessing risks relies heavily on SSA providers. These include:

* Government Agencies: The U.S. Space Force (through Space Delta 2), the European Space Agency (ESA), and other national space agencies.

* Commercial Companies: LeoLabs, slingshot Aerospace, and others are providing increasingly sophisticated SSA services.

* Data Fusion: The challenge lies in fusing data from multiple sources to create a comprehensive and accurate picture of the space habitat. The ITU could play a role in facilitating this data fusion.

Case Study: The 2009 Iridium-Cosmos Collision

The 2009 collision between an active Iridium satellite and a defunct Russian Cosmos satellite dramatically illustrated the dangers of space debris. This event created thousands of new debris fragments,significantly increasing the risk to other satellites. This incident underscored the urgent need for improved space debris mitigation and collision avoidance strategies. It also highlighted the limitations of existing tracking capabilities at the time.

Benefits of Enhanced ITU Coordination

A more proactive and coordinated approach to space safety, spearheaded by the ITU, offers several benefits:

* Reduced Collision Risk: The most obvious benefit is a decrease in the probability of collisions, protecting valuable space assets.

* Sustainable Space Access: Ensuring the long-term sustainability of space activities for future generations.

* Lower Insurance Costs: Reduced risk translates to lower insurance premiums for satellite operators.

* Increased Investment: A more stable and predictable space environment encourages further investment in space technologies.

* Preservation of Critical Infrastructure: Protecting essential services that rely on satellites, such as dialog, navigation, and weather forecasting.

Practical Tips for Satellite Operators

Even before the ITU implements new coordination mechanisms, satellite operators can take steps to enhance their own space safety practices:

* Invest in SSA Services: Subscribe to reliable SSA services to receive timely and accurate collision warnings.

* develop Robust Maneuver Plans: Have pre-planned maneuver strategies in place to respond to conjunction alerts.

* Implement Automated Systems: Explore the use of automated collision avoidance systems.

* Share Data: Actively participate in data sharing initiatives wiht other operators and SSA providers.

* Adhere to Best Practices: Follow established guidelines for responsible space operations, including debris mitigation and end-of-life disposal.
