I have to wonder if anybody else lost satellites. Starlink is at an especially low orbit, so either they were really unlucky, or they have poor radiation shielding.

[EDIT] OK I made the wrong assumption that this was due to radiation, but it was due to the atmosphere being 50% more dense than usual due to the storm, which led to failure of the satellites. This makes good sense. Next time I'll read TFA before I comment!



The Starlink satellites are launched into a very low orbit, and raise to their final orbit.

These satellites had just launched, and had not yet raised their orbit, so they were lower than the rest of the constellation.

> SpaceX deploys its satellites into these lower obits so that in the very rare case any satellite does not pass initial system checkouts it will quickly be deorbited by atmospheric drag. ...

> Unfortunately, the satellites deployed on Thursday were significantly impacted by a geomagnetic storm on Friday.

So, while Starlink's final orbit is lower than (almost?) all other satellites, these satellites were even lower than that. I would be very surprised if any other satellites were effected.


This method of parking in a lower orbit is also why the trains of satellites are highly visible for a few weeks after launch. They extend their solar panels horizontally to minimize drag, which causes them to reflect the sun just after dusk and just before dawn. Once they reach their higher orbit they reorient their panels perpendicular to the earth, greatly lowering their apparent brightness.


The page says that they are deployed out of the ship at very low altitudes before they climb to their final orbit. So I think this only applies very early on in the deployment process and wouldn’t impact anyone else, or even existing deployed starlink satellites. They even describe why they start lower than normal in the article ;)


Out of curiosity, I found this article:

https://en.wikipedia.org/wiki/List_of_USA_satellites

Quite a number of satellites listed as "failed."


It was due to increased atmospheric drag, not a direction result of radiation.
