I wrote a while back that the Zuma satellite mission might not have been real. Well, SpaceX launched it yesterday, Sunday January 8, and there is still no indication that a real satellite was launched. While the Zuma mission is secret, rumors today are that the mission failed. See 1 2 3 4 and the best article so far. SpaceX claims that nothing went wrong on their side. My surmise is that this mission was for the purpose of evaluating SpaceX readiness to perform launches for government intelligence, and like the Falcon Heavy demo (which is carrying Elon’s Tesla Roadster) might not have been carrying a functional payload.
