SpaceX - where did you send that red Tesla Roadster and Starman? Falcon Heavy liftout from Cape Canaveral was awesome! There is a copy of Douglas Adams' 1979 novel The Hitchhiker's Guide to the Galaxy in the glove box, along with a towel and a sign on the dashboard that reads "Don't Panic!" Following the successful launch, the payload was given the USSPACECOM Satellite Catalog Number of 43205 with a description of "Tesla Roadster/Falcon SH" along with the International Designator of 2018-017A.
