SpaceX's Starlink division confirmed an anomaly with satellite 34343 at around 560 km altitude, resulting in loss of contact and the satellite breaking into tens of pieces. LeoLabs detected the fragment creation event using its radar network in the Azores, Portugal, and described it as likely caused by an internal energetic source. The company stated there is no new risk to other space operations.
SpaceX announced on March 30 that Starlink satellite 34343 experienced an on-orbit anomaly, leading to a loss of communications. The incident occurred at approximately 560 km above Earth. Starlink emphasized that the event poses no new risk to the International Space Station, its crew, NASA's Artemis II mission, or the recent Transporter-16 launch. The teams are monitoring trackable debris and coordinating with NASA and the US Space Force while investigating the root cause to implement corrective actions if needed. LeoLabs, which tracks objects in low Earth orbit, reported detecting tens of objects near the satellite shortly after the event during a radar pass over its site in the Azores. The firm noted that additional fragments may emerge as analysis continues and assessed the breakup as stemming from an internal energetic source rather than a collision. Due to the low altitude, fragments are expected to de-orbit within weeks. This marks the second such incident for Starlink, following a similar fragment creation event on December 17, 2025, also producing tens of objects from an apparent internal source. In response to that earlier anomaly, Starlink described venting from the propulsion tank, tumbling, and eventual atmospheric reentry. The company then committed to software updates for mitigation. Starlink satellites are designed for demisability, ensuring they fully burn up on reentry with negligible ground risk. Normal end-of-life procedures target reentries over open ocean areas.
