Since the whole original headline is too long, I'd suggest "The tale of Europe’s Galileo satellites going dark"

Emailing [email protected] frequently produces a fairly quick remedy.

I've suggested borrowing from the lede: "Key details about the failure of Europe’s Galileo satellite system over the summer have started to emerge - and it’s not pretty."

"Key details of Galileo satellite summer failure emerge" should work, at 55 characters (limit is 80).

That's the suggestion I'd submitted.

We'll take it. Thanks!
