Nasa's statement today added: "If supported by the market, the agency can accommodate up to two short-duration private astronaut missions per year to the International Space Station". Russia, however, has allowed several private astronauts on the station.
More than 50 companies are already conducting commercial research and development on the space station through the ISS US National Laboratory.
"The commercial entity developing the mission will determine crew composition for each mission and ensure private astronauts meet NASA's medical standards and the training and certification procedures for International Space Station crew members".
And it'll cost you: Upwards of $35,000 per night for room and board - and air - at the International Space Station.

Fielding at deep backward square, Cottrell hared around the boundary as Smith's sweetly hit shot looked headed for six runs. But that's how cricket plays and we know Australia are a quality side.
The space station does not belong to NASA.
"A robust low-Earth orbit economy will need multiple commercial destinations, and NASA is partnering with industry to pursue dual paths to that objective that either go through the space station or directly to a free-flying destination". It has limited space tourism up to 2 per cent and limits the uses of the Space Station resources up to 5% to the commercial activities.
The announcement comes as the agency is trying to return humans to the moon by 2024, a mission that officials said would require significant additional funding.
Traveling to space is very close to being a reality.
