Spacecraft from Chinese launch nearly slammed into Starlink satellite, SpaceX says
A Critical Moment in Space: Close Call Between Chinese Satellite and Starlink
In a stark reminder of the growing complexity of space operations, a Chinese satellite narrowly avoided a collision with a Starlink satellite on December 9, 2025. The incident highlights the pressing need for improved coordination and deconfliction between satellite operators in Earth orbit.
According to SpaceX, the Starlink satellite, identified as STARLINK-6079 (56120), was at an altitude of 560 kilometers when it came within 200 meters of the Chinese satellite. This close approach was the result of a lack of coordination and deconfliction between the two satellite operators, which is a common challenge in the increasingly crowded space environment.
The Growing Problem of Space Debris
The number of functional satellites in Earth orbit has skyrocketed from fewer than 3,400 in 2020 to approximately 13,000 today. This rapid growth has led to a significant increase in the risk of collisions and the creation of space debris. The Kessler syndrome, a catastrophic scenario in which a single collision generates a massive cloud of debris, is a pressing concern for the space community.
Starlink, operated by SpaceX, has taken steps to mitigate this risk by implementing autonomous collision avoidance maneuvers. In the first six months of 2025, Starlink spacecraft performed approximately 145,000 avoidance maneuvers, which works out to around four maneuvers per satellite per month. However, even with these measures in place, there is still a risk of collisions with satellites that do not share their trajectory data or do not have the capability for autonomous avoidance.
The Role of CAS Space and Kinetica 1
CAS Space, the launch services provider responsible for the Kinetica 1 rocket, has come under scrutiny for its handling of the incident. While CAS Space claims to have followed standard procedures for launch window selection and collision avoidance, the company is currently investigating the incident to determine the exact circumstances surrounding the close approach.
The Kinetica 1 rocket, a 100-foot-tall solid-fuel rocket, was used to launch six Chinese multifunctional satellites, an Earth-observation satellite for the UAE, a scientific satellite for Egypt, and an educational satellite for Nepal. The incident highlights the need for improved coordination and deconfliction between satellite operators, particularly in the context of international collaborations and shared launch services.
Implications and Forward-Looking Thoughts
The close call between the Chinese satellite and Starlink has significant implications for the space community. As the number of satellites in Earth orbit continues to grow, the risk of collisions and the creation of space debris will become increasingly pressing concerns. Improved coordination and deconfliction between satellite operators, as well as the development of more effective collision avoidance systems, will be critical to mitigating these risks.
In the context of international collaborations and shared launch services, the incident highlights the need for clear communication and coordination between satellite operators. The development of standardized procedures and protocols for launch window selection and collision avoidance will be essential to ensuring the safe and efficient operation of satellites in Earth orbit.
Ultimately, the close call between the Chinese satellite and Starlink serves as a stark reminder of the importance of responsible and sustainable space operations. As the space community continues to grow and evolve, it is essential that we prioritize the development of more effective collision avoidance systems, improved coordination and deconfliction between satellite operators, and a deeper understanding of the risks and challenges associated with space debris.
