These are mockups of what four years from now (if all goes well) will be the first privately owned space station in orbit. According to The New York Times:
"Four years from now, the company plans for real modules to be launched and assembled into the solar system's first private space station. Paying customers -- primarily nations that do not have the money or expertise to build a space program from scratch -- would arrive a year later.
In 2016, a second, larger station would follow. The two Bigelow stations would then be home to 36 people at a time -- six times as many as currently live on the International Space Station."
If you'd like to stay on the station for 30 days, it will cost you just $25 million. Bargain!
