Reentered and Bad Starlinks

Deorbited, Malfunctioning and anomalous Starlinks

[Updated 2021 Apr 7 (at least, and possibly more recently)]
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:

2021 Mar 31 SpaceX table

At the end of Mar 2021 SpaceX provided a table of failed Starlinks per launch to the FCC, giving the number `non-manueverable above injection altitude' (Non-Mvble), `screened at low altitude' (Screened), and `deorbited early' (DO Early). The launch number ids in the document (DocLNo) are not quite the same as those in other SpaceX info (SpX LNo) and appear not to be in chronological order. Columns headed 'SpX' are data according to SpaceX, 'JCM' indicates my own estimates for comparison. "Not launched" means not launched at the date of the SpaceX table.

This table is preliminary - there's a mismatch because the rideshares with 58 and 57 sats should be V1.0-L8/9/10 not V1.0-L9/10/11. I hope to update it over the coming week.

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.

The "SPX Fail" column indicates whether SpaceX acknowledge the satellite as inactive as reflected on the SpaceTrack.org `satellite' query class. (Yes = SpaceX say it is dead; Yes (NM) = SpaceX say it is not manuevering, but still alive in other ways; No = SpaceX say it is still active despite my data).

Starlink 48 resumed orbit changes in Nov 2020.

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.
