It is described as largely intact, but is currently “tumbling, and will reenter the Earth’s atmosphere and fully demise within weeks,” says the official Starlink X account. Geospatial intelligence partner Vantor shared what is likely the last clear image of the ill-fated satellite after SpaceX urgently requested visual intelligence.
On December 17, Starlink experienced an anomaly on satellite 35956, resulting in loss of communications with the vehicle at 418 km. The anomaly led to venting of the propulsion tank, a rapid decay in semi-major axis by about 4 km, and the release of a small number of trackable… December 18, 2025
We don’t have a clear description of what exactly happened with satellite 35956. Starlink just describes the problem as an “anomaly” that occurred on December 17. Engineers working for Starlink are said to be “rapidly working to root cause and mitigate the source of the anomaly.” No insight into this investigation is ready yet, but apparently, some software changes are already being deployed that “increases protections against this type of event.”
It was observed that satellite 35956 lost communications at an altitude of 418km. “The anomaly led to venting of the propulsion tank, a rapid decay in semi-major axis by about 4 km, and the release of a small number of trackable low relative velocity objects,” says Starlink.
