But excitement for the long-awaited Launch has gone far beyond space nerds and Musk enthusiasts: NASA has sold out $195 tickets to a viewing party featuring a champagne toast and a commemorative glass.

The spectacle has even tempted a five-year-old fanboy into begging Musk for tickets, and the Kennedy Space Center reported a website jam as would-be watchers scrambled to buy their way in.

The project took a big leap forward in December when the massive rocket went vertical at 39A, the historic launch pad at Florida’s Kennedy Space Center that sent Apollo astronaut Neil Armstrong to the moon.

The Hawthorne, California-based company already has paying customers committed to flying with the new rocket, including commercial satellite operators Arabsat, Inmarsat and Viasat, its launch manifest shows.

Because of the experimental nature of the first flight, and perhaps as a way to burnish the spectacle, Musk decided the payload will be his personal Roadster sports car made by another one of his companies, Tesla Inc., that will be set to play David Bowie’s “Space Oddity” on repeat as it’s hurled into the deep beyond.
