Last week, I, along with millions of others, held my breath as we watched SpaceX’s large Starship make its second test flight. It looked to be a successful launch as Starship traveled farther than ever before, successfully reaching space only to blow up shortly after separating from its booster. Was it a success? Absolutely. But SpaceX has a ways to go before realizing Elon Musk’s dream of colonizing Mars.
SpaceX is just one of the many companies founded or led by Musk, the mercurial billionaire who has launched at least 10 companies in the past quarter century. Fortune has set out to accomplish its own herculean goal: mapping out Musk’s myriad ventures. We wanted to show you where all of Musk's companies, that we know of, are located. This task was made more complex because none of them returned our requests for information. Most of the data for our map came from the websites of various companies, SEC filings, state corporation documents, and press reports.
