(6) US space startup company Bigelow Aerospace has also seen the potential for hotels in space, but with a completely different design: expandable space station modules. An expandable module is a space structure that has a flexible outer shell. when it is in orbit, the module is inflated, creating a larger work, play and living area for astronauts. The expandable modules were designed by NASA (National Aeronautics and Space Administration) for a space programme. When this was cancelled, Bigelow Aerospace was given the right to commercialise some of the technology. A major advantage of inflatable modules is that the walls are flexible, which is better than rigid ones for protecting a module from the impact of space debris. The expandable modules could be used for space tourism and for orbital hotels. Bigelow plans to launch in the near future an orbital resort, which will probably be called CSS (Commercial Space Station) Skywalker
