Reentered and Bad Starlinks

Deorbited, Malfunctioning and anomalous Starlinks

[Updated Sep 6]
All altitudes in km. SpaceX have acknowledged ( Doc 1 and Doc 2 ) a number of satellites which have lost manuevering capability. However, they do not provide enough information to tell WHICH specific satellites are being referred to. Here I present my own summary of Starlink orbital behaviour that suggests certain satellites have failed. Summary table:
Launch Sats launched Deorbited Reentered after fail Still in orbit Not manueveringWorking?
Launch 0 (Tintin) 2 2 0 0 0
Launch 1 (V0.9) 60 29 0 31 8 23
Launches 2-12 (V1.0) 653 4 1 648 16 632
Total 715 35 1 679 24 655

Satellites from Launch 1 (V0.9 design)


My analysis based on TLEs and SupTLEs:

Satellites in orbit undergoing uncontrolled orbital decay

Failed satellites often are manuevered to different orbits for a while before beginning steady decay. The dates here are when steady decay began.

Satellites actively deorbited:

Two V0.9 satellites were deorbited early in 2020. They appear to have been test satellites evaluating low altitude operations, rather than failures. More V0.9 satellites were actively deorbited in summer 2020.
