SpaceX—Starlink satellite failure in December 2025 created debris field in low Earth orbit
In December 2025, a batch of Starlink satellites experienced anomalies shortly after deployment, resulting in uncontrolled reentry and debris creation. The incident highlighted risks associated with rapid mass satellite deployment and raised questions about quality control in SpaceX's high-volume manufacturing process. Space tracking agencies monitored the debris for potential collision risks with other spacecraft.

Starlink satellite 35956 failed on December 17, 2025 creating hundreds of tracked debris objects in orbit
On December 17, 2025, Starlink satellite 35956 (launched November 23, 2025) experienced an anomaly at 418 km altitude described as 'likely caused by an internal energetic source.' The incident resulted in propellant tank venting, release of trackable debris objects, and rapid altitude decay. Former ISS astronaut Ed Lu noted 'hundreds' of debris objects were being tracked and had spread to 6,000 km over the orbital track within days. The satellite is now tumbling and will reenter Earth's atmosphere within weeks. Starlink stated the release was of 'a small number of trackable low relative velocity objects' and teams are working to determine the cause while deploying software updates for similar event prevention.
