Fresh off its historic and successful mission to the International Space Station, last week SpaceX announced even grander plans.

Company founder Elon Musk, took to Twitter, if you can believe it, to announce that the company is planning to construct floating, marine-based spaceports around the world. These aqua-bases would be used to launch rockets into space, including Mars and the moon, as well as to support hypersonic passenger flights around the globe.
