This is pretty wild. The Rocket Racing League seeks to combine the excitement of NASCAR and rocketry. The hope is that just as auto racing helps advance the automotive industry, Rocket Racing will "serve as a technology accelerator in the areas of airframe, propulsion and spacecraft design..."
They'll generate revenues through sponsorships, broadcast rights, ticket sales, tours and merchandising. They've seem to have a decent business plan. Let's hope it becomes the Next Big Thing and not the next XFL.
