More than 120 pages of proposed rules released by the government Thursday regulate the future of space tourism. This don't-forget list touches on everything from passenger medical standards to preflight training for the crew.
Before taking a trip that literally is out of this world, companies would be required to inform the "space flight participant" — known in more earthly settings as simply a passenger — of the risks. Passengers also would be required to provide written consent before boarding a vehicle for takeoff.
Legislation signed a year ago by President Bush and designed to help the space industry flourish prohibits the Federal Aviation Administration from issuing safety regulations for passengers and crew for eight years, unless specific design features or operating practices cause a serious or fatal injury.
"This means that the FAA has to wait for harm to occur or almost occur before it can impose restrictions, even against foreseeable harm," the proposal says. "Instead, Congress requires that space flight participants be informed of the risks."
Physical exams for passengers are recommended, but will not be required, "unless a clear public safety need is identified," the FAA says in the proposed regulations.
Passengers also would have to be trained on how to respond during emergencies, including the loss of cabin pressure, fire and smoke, as well as how to get out of the vehicle safely.
Pilots, meanwhile, must have an FAA pilot certificate and be able to show that they know how to operate the vehicle. Student or sport pilot licenses would not qualify.

Each member of the crew must have a medical certificate issued within a year of the flight, and a crew member's physical and mental state must "be sufficient to perform safety-related roles," the rules say.
The FAA also would require each crew member to be trained to ensure that the vehicle will not harm the public, such as if it had to be abandoned during a flight emergency.
The legislation that Mr. Bush signed last year tasked the FAA with coming up with rules to regulate the commercial space flight industry, which has been slowly getting off the ground.
Laws governing private sector space endeavors, such as satellite launches, have existed for some time. But there previously has been no legal jurisdiction for regulating commercial human spaceflight.
In 2001, California businessman Dennis Tito became the world's first space tourist when he rode a Russian Soyuz capsule to the international space station. Mark Shuttleworth, a South African Internet magnate, followed a year later on a similar trip, also paying $20 million for the ride.
Last year, in a feat considered a breakthrough for the future of private spaceflight, Burt Rutan won the $10 million Ansari X Prize by rocketing his SpaceShipOne to the edge of space twice in five days.
Two months ago, Greg Olsen, who made millions at a Princeton, N.J., technology company,, also on a jaunt to the international space station.
The 123-page proposal was published Thursday in the Federal Register, the government's daily publication of rules and regulations, and will be subject to public comment for 60 days, through Feb. 27.
Final regulations are expected by June 23.
