Maybe Zuma is gone, maybe it isn't:

"Rumors are swirling about the fate of a top-secret spacecraft, known as Zuma,
which Northrop Grumman supposedly built for an unknown U.S. government agency and
launched aboard a SpaceX Falcon-9 rocket on Jan. 7, 2018. There are a number of
theories about what might have happened already circulating, but a fairly obvious
one seems glaringly absent: that the satellite didn't crash at all and that it’s
working as planned."
