"Keeping people healthy in space has been a major challenge since the first days of spaceflight ... Now, however, the burgeoning business of commercial spaceflight is poised to [transport] .... unhealthier pool of passengers." - Katherine-Harmon Courage, "Space: The Final Medical Frontier," Scientific American, March 2014 (sub. req.)
The commercial and public excitement over space tourism masks the severe health threats. They become all the more likely because the middle aged are most vulnerable. And they constitute the prime target market for this pricey adventure. As Courage points out in the Scientific American article, the body compression during takeoff and landing puts strain on all bodily systems. Of course, there could be heart attacks, including fatal ones. Post-flight there could be enduring medical problems with bones, muscles, vision and the ability to fall asleep and stay asleep.
Of course, both the providers of space travel and the consumers will be turning to lawyers. Companies will have to insulate themselves from all sorts of liability. They may borrow from the approach of the occult industry which positions its consumer readings as for "entertainment only." In addition, they have to anticipate criminal charges for alleged negligence and even fraud (misrepresenting a nausea-filled ordeal as a fun time.)
On the other hand, consumers who wind up with alleged compromised health systems after the junket could high-tail it to a personal injury lawyer. In the worst-case scenario, if consumers die on the tour, their families are bound to sue.
Meanwhile, as industry prepares for the first commercial flight, lawyers could be publishing articles and lecturing on the legal threats and possible solutions. Their stance should be that they want to enable this niche industry, not impede it. Through this outreach they could be attracting new business for their firms' current practices. Opportunity often comes sideways.
