There are several revenue streams that are near and present that could support a private space station, including in-space manufacturing, microgravity research, and tourism - for both individuals and sovereign nation astronauts - and in-space supply logistics.

The economics of the space industry are changing. Within so called 'NewSpace,' not only are new entrants being created almost daily, the business models and capital sources have proven to be dramatically different from traditional models built upon large government contracts and defence-related spending.

The bottom line is 2018 should finally be the year where we see the early stages of broad-based commercial space tourism appear. Demand will certainly be driven by the early successes or failures of those missions, the marketing of those missions, as well as the propensity for tourists to become repeat flyers.

The case for sponsorships in commercial spaceflight is compelling and could dramatically impact the economics of space tourism. Global brands are looking for fresh, new ways to position themselves on the leading edge of their categories.
