“the event was likely caused by a piece of debris in the 1-10 centimeter size range.”
The breakup of Yunhai-1 (02) is the fifth confirmed accidental collision between two cataloged objects, according to the report. A total of 37 fragments from the collision have been cataloged by the 18 SPCS and as of 1 October 2021, with four of these having reentered the atmosphere.

Open Access Hubhttps://scihub.copernicus.eu/news/News00980Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, the resuming of the operations was carefully prepared including the on-board configuration changes preventing the anomaly to occur again.
However, during the preparation of the recovery operations, it became clear that the initial anomaly was a consequence of a potential serious problem related to a unit of the power system of the Sentinel-1B satellite. The operations performed over the last days did not allow to reactivate so far a power supply function required for the radar operations.
Further investigations to identify and remedy the root cause will be performed over the next days.
