In space, no one can hear you scream...(except for fellow astronauts)

An interesting article in New Scientist about "etiquette" recommendations to future space tourists. Much of it is obvious (be tidy to help prevent tensions with the other astronauts), but this risk of motion sickness drugs I had not heard before:

Space sickness will likely be a big issue for novice space flyers – even highly trained test pilots still get queasy in the new environment of microgravity. Buckey says medication will probably be part of the solution.

When NASA scientists started giving anti-motion sickness drugs to students who flew experiments on the C-9 aircraft that simulates weightlessness, they noticed a much lower rate of motion sickness than in students who had not taken the drug.

But the drug they inject to quell space sickness, promethazine – sold under the brand name Phenergan, has its own set of problems. In space, Phenergan has been linked to urinary retention. Four crew members have had to have catheters inserted into their bladders during spaceflights.
