NASA Ponders Transporting Tourists to International Space Station, WS Journal (link probably won't work)
"But for the first time, a senior National Aeronautics and Space Administration official on Thursday publicly talked about ways the U.S. eventually could offer the same service and reap similar benefits. The trips could begin later this decade, when a new generation of private, U.S.-built space taxis is expected to begin transporting American crews into orbit. "We are very, very open" to the possibility and intend to "work on details with the company or companies" that end up winning contracts to take American astronauts back and forth from the station, NASA Deputy Administrator Lori Garver told reporters during a teleconference."
Keith's note: To expand further on my question (described above), I noted that people have been able to fly to the ISS via commerial means for over a decade but their trips are explicitly considered as being via Russia's participation. Use of any U.S. facilities is usually at extra expense to the customer. I asked if NASA was considering A. Allowing individuals to buy seats to visit the U.S. segment B. allowing commercial concerns to be able to send up their own astronauts for periods longer than just a brief visit and C. how would NASA seek to determine the charge(s) for these visits. Lori Garver answered as noted above. I then asked how such trips might be arranged - i.e. if they'd be done via CASIS (which is supposed to me managing commerical research in the ISS National Lab) or some new TBD arrangement. Garver replied "No - I haven't heard any discussion about this and CASIS." She also noted that NASA has "come a long way since Dennis Tito when NASA wasn't even certain if they'd open the hatch."
