SpaceX to reposition 4,400 Starlink satellites following safety concerns raised by China

SpaceX has announced plans to lower the orbits of over 4,400 Starlink satellites in response to safety concerns raised by China. The reconfiguration, set to take place throughout 2026, is aimed at reducing the risk of collisions in space and addressing warnings about the potential hazards posed by the satellite network.

Addressing Safety Risks in Crowded Orbits

The decision comes after a representative from Beijing criticized the Starlink constellation during an informal meeting of the United Nations Security Council. The representative warned that the project crowded shared orbital resources and increased the likelihood of crashes in space. Following this, SpaceX unveiled its plan to relocate satellites to a lower orbital altitude to address these concerns.

Michael Nicolls, vice president of engineering at Starlink, confirmed the company’s course of action in a social media statement issued Friday, January 2, 2026, China time. "Starlink is beginning a significant reconfiguration of its satellite constellation focused on increasing space safety", Nicolls stated.

Lower Orbit for Enhanced Safety

The reconfiguration will involve moving satellites currently orbiting at approximately 550 kilometers (342 miles) to a lower altitude around 480 kilometers. According to Nicolls, this adjustment is intended to enhance space safety by condensing the satellite orbits and avoiding the more crowded regions of low Earth orbit.

"Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways", Nicolls explained. He further noted that the orbital region below 500 kilometers is less congested with debris and other satellite constellations, leading to a "significantly lower aggregate likelihood of collision."

Benefits of the Reconfiguration

SpaceX has also emphasized the benefits of this orbital adjustment. Nicolls stated that the new altitude would result in an "80 percent reduction in ballistic decay time" during the anticipated solar minimum, which is expected to occur around 2030. Ballistic decay time refers to the time it takes for an object in orbit to fall back to Earth. The shorter decay period would allow defunct satellites to deorbit more quickly, decreasing the amount of debris in space.

The move places Starlink satellites closer to altitudes occupied by other key space infrastructure, such as the International Space Station, which orbits at approximately 400 kilometers, and China’s Tiangong space station, which orbits between 340 and 450 kilometers. However, SpaceX asserts that the new configuration will improve the overall safety of its network.

Coordinated Efforts with Stakeholders

SpaceX stated that the significant reconfiguration will be closely coordinated with regulators, other satellite operators, and the United States Space Command to ensure a smooth transition. The company’s objective is to support international efforts to maintain the safety and sustainability of operations in increasingly crowded orbital regions.

As the year progresses, the repositioning of Starlink satellites will remain a key development in the conversation surrounding space safety and the responsible management of orbital resources. For now, SpaceX’s efforts signal a commitment to addressing the concerns raised by China and other stakeholders in the global space community.
