The term "affordable" used here is relative. A 12-day stay at this space extravaganza will cost around $9.5 million or £6.7 million. Now why Frank says "affordable" is because from 2001 to 2009, seven private citizens have taken trips to the International Space Station (ISS), paying an estimated amount of $20 million to $40 million each! Relative to that amount, it does sound affordable!
Frank added up saying that Orion Space is building the Aurora Station itself and some of its engineers, who apparently helped design and operate the ISS, are making the hotel in Houston. They are developing software which is required to operate it in the Bay area.
The size of the Aurora Station can be compared to that of a large private Jet's cabin. It'll be 14.1 feet wide by 43.5 feet long (4.3 meters by 13.3). It would also feature a pressurized volume of 5,650 cubic feet (160 cubic m), Orion Span representatives said.
To put it into perspective, the International Space Station is 357 feet (109 m) long and has an internal pressurized volume of 32,333 cubic feet (916 cubic m).
