Starlink Satellite 35956 Suffers In-Orbit Anomaly, Tumbles Toward Reentry

SpaceX says engineers are deploying software updates across the constellation to increase protections against similar events.

Overview

  • A Dec. 17 anomaly at about 418 kilometers caused loss of communications, venting of the propulsion tank, a roughly 4-kilometer orbital drop, and a small number of trackable objects.
  • SpaceX reports the satellite remains largely intact and tumbling and is expected to fully burn up in Earth’s atmosphere within weeks.
  • LeoLabs says its radars detected tens of objects and assesses an internal energetic source as the likely cause rather than a collision.
  • SpaceX is coordinating with the U.S. Space Force and NASA to monitor the fragments, and the satellite’s path is below the International Space Station with no risk to the crew.
  • The incident follows a reported close approach involving a Chinese-launched payload and a Starlink satellite, which CAS Space has disputed, underscoring calls for better operator coordination.
